The Effect of Changing Gold Prices on Artisanal Mining

Over the past year as the price of gold has fallen, many have asked how artisanal miners will be affected. Some have speculated that the drop in the price of gold would lead to less artisanal mining activity - as it has for the industrial gold mining sector. But this is not generally the case. On the contrary, in many places it continues to grow. And this has also been true historically. Even through the 1990's when the gold price descended to levels 4 or 5 times lower than today's, artisanal mining persisted and continued without any significant contraction.
For the majority of artisanal miners there is simply no other job that pays anywhere near as much

A falling gold price may slow the growth in artisanal mining but rarely leads to the kind of reductions and contractions that are symptomatic of the formal large scale mining and gold exploration businesses. In large part this is because the wages earned by artisanal miners are much greater than their rural agricultural alternatives (farming) - often five times as high. For the majority of artisanal miners there is simply no other job that pays anywhere near as much. And because capital costs are very low and labour costs are not fixed the gold price threshold below which a mining operation is no longer economical is far lower and less rigid for artisanal miners than it is for the formal industrial sector. Overall, people enter the sector when the price increases but the population rarely decreases. Individuals may come and go but the number of miners is typically steady or increasing. One implication of this dynamic is that, as the gold price falls, the proportion of gold production from artisanal miners will actually grow, as their numbers remain steady and the formal gold sector contracts. Artisanal miners are also quicker at capturing the benefits of price increases because the time needed to increase production is very short. They can be very responsive to opportunities. These qualities - that they don't fall away with price drops but can also quickly act on price increases - mean that artisanal gold miners are likely to be a durable and increasing presence in gold mining in the coming years. Particularly if there were to be a series of gold price shocks. This would likely diminish the relatively sluggish and capital intensive industrial sector while resilient artisanal gold miners continued through both ups and downs.
As the gold price falls, the proportion of gold production from artisanal miners will actually grow
The importance of artisanal gold mining as a livelihood for millions of the world's poor as well as the likelihood that it will be a durable feature of the gold mining sector for the foreseeable future are strong reasons for governments and industry to adopt policies and innovative approaches to help the artisanal sector improve its environmental and social practices to accelerate its transition into a more responsible and beneficial industry. Under any likely foreseeable gold price scenario, artisanal gold mining is here to stay. We can continue to chase them around in circles as we have for the last few decades or we can buckle down and help them improve.

Mercury Recycling in Artisanal Gold Mining: The Good and the Bad

The promotion of simple mercury recycling technologies called retorts to reduce human exposures and environmental contamination is one of the most widely recommended interventions in artisanal and small-scale gold mining (ASGM) communities. However if they aren't introduced correctly, retorts are often abandoned or misused, which wastes resources and develops cynicism from miners, prevents reduction of environmental contamination, and in some cases actually increases mercury exposures.

Retorts are relatively simple devices that condense and collect the mercury vapour released from heating gold mercury amalgam. The collection and capture of mercury is important to reduce both the amount of mercury contamination released into the air and to reduce direct human exposure. There are many different types of retorts – from simple kitchen bowl retorts made from a series of bowls purchased from the local market, to custom welded retorts with water-cooled condensers.
Retorts are relatively inexpensive to build and operate, they are simple and intuitive in construction and use, and they can significantly reduce environmental contamination and human exposure. However, in order for them to do this successfully, proper instruction with sufficient education is crucial. To illustrate this, here are three case studies and lessons from the AGC’s field work (names are changed):

1. Financial incentives for using retorts can be misleading.

After a day's work, Babakar adds mercury to his concentrated ore. After squeezing the excess mercury through a piece of t-shirt cloth, he has a half gram of amalgam, which is about 50% gold and 50% mercury. He then uses a propane blowtorch to heat the silver ball on a pan for about 3 minutes. He and his family like to watch the silver ball turn golden as the mercury vaporizes. He then walks over to the gold buyer and sells his sponge gold for $8.20[1]. The value of the lost mercury is around 5-10 cents, or less than 1% of the value of the recovered gold. Babakar could use his neighbours retort but never does because it takes too much time and fuel – about 20 minutes to heat the retort and using his own propane canister, which costs far more than the 5-10 cents he would save from the recovered mercury. However if Babakar knew that he was harming his health and the health of his family from mercury exposure, there is a higher chance that he would decide that it is worth the time and money to use a retort – even for such a tiny bit of amalgam.

  • Retorts don’t always save money and in some cases actually incur a cost, especially for small amounts of amalgam.
  • Promoting the financial benefits of retorts with out a proper cost benefit understanding is risky and can fail; but health benefits of proper use are universal.
2. Field retorts always leak dangerous mercury vapour and need to be used outside.

When retorts are introduced into Mariam's community she is relieved to have a tool to protect herself and her family from mercury, which she had heard is dangerous and possibly illegal. Her husband now uses the new retort donated to him to burn the amalgam in their house. On a typical day, her husband burns about 3 grams of amalgam in a retort that is approximately 95% efficient at capturing mercury. This efficiency is typical of a well-designed field retort that is used correctly, but some only capture 80%. The 5% of the mercury vapour that leaks from the retort produces an indoor air concentration that is  50 times higher than the WHO occupational limit [2]. In addition to the acute exposure, burning indoors will also cause long-term chronic exposure to the family because mercury sticks to the household walls and surfaces and is re-emitted overtime into the air.

Burning amalgam indoors, even with a retort, causes acute and long term mercury exposure.
  • If mercury is illegal, burning inside of houses or cars becomes more common.
  • Retorts should never be used in areas that women and children frequent because they are much more sensitive to mercury poisoning.
3. Used retorts are highly contaminated and emit mercury vapour into any area where they are stored or transported.

Lemah is very happy when a pilot project was launched in his community and he was chosen to receive a retort.  Only 10 retorts were given out and he was eager to use it. He and some friends use the retort outside where they apply the heat but then he stores it under his bed when he isn't using it for safe keeping. While it is stored under his bed, the retort releases residual mercury vapour into his bedroom exposing himself and his family to dangerous levels over long periods of time.       
  • Retorts should always stay outside or in a dedicated contamination zone with good ventilation.
  • Retorts should not be transported inside the passenger cabin of a car.


Retorts can be an excellent tool in reducing mercury consumption, environmental contamination and human exposure if they are introduced with the proper training and education. However, without a carefully thought-out intervention, the intended benefits of retorts can fail and in some cases actually increase human exposure to mercury. This is particularly concerning when women and children are endangered through unintended secondary exposures, as they are more susceptible to mercury toxicity.  With the creation of the Minamata Convention, mercury-reduction interventions in ASGM communities will certainly increase, and so too will the importance of proper retort training. When a retort intervention is being planned, consider these three key points:
  1. Retorts don’t always save money so other incentives need to be explained and re-enforced such as the protection of health.
  2. Retorts leak mercury so they must be used outdoors and away from women and children.
  3. Used retorts are contaminated and continuously emit residual mercury, so they must be stored in a dedicated well-ventilated contamination zone (typically outside) and not be transported in a closed car.


[1] Calculation of value of 0.52 g of sponge gold:
Spot $ = $1400/toz (31.1 g/toz) = $45/g
Sponge gold is 50:50 Au:Hg, 0.26 g of gold
Miners in most regions get at least 70% of spot price in the field.
0.26 g Au = ($45/g * 0.26 g * 0.70) = $8.19
Field price of Hg = $200/kg = $0.2/g
0.26 g of Hg = 0.247 g of Hg = $0.05
$0.05/$8.19 * 100 = 0.6%
~ The relative cost of the lost Hg is < 1% of the value of the gold.  

[2] Calculation of Hg air concentrations:

1. Inside a hut without a retort
Volume of a hut = volume of a cone + cylinder
Cone : height = 2 m; radius = 2 m; volume =  1/3piR2 = 4.189 m3
Cylinder: height = 2 m; radius= 2 m; volume = piR2H = 25.13 m3
Air volume of a hut = 4.189 + 25.13 = 30 m3
Air concentration if 1.5 g of Hg is burned (50% of amalgam is Hg, 50% is gold) = 1.5 g/30m3 = 1,500,000,000 ng/30m3  = 50,000,000 ng/m3
The WHO occupational limit for Hg concentrations in air = 50,000 ng/m3
50,000,000 ng/m3 /50,000 ng/m3 = 1000
~ The mercury air concentration in the hut would be 1000 X higher than the occupational limit.

2. Inside a hut with a retort
Retorts are ~95% efficient at capturing mercury (5% in the air of the hut)
Air concentration (from calculation 1. above) = 0.05 * 50,000,000 ng/m3 = 2,500,000 ng/m3
2,500,000 ng/ m3/50,000 ng/ m3= 50
~ Even with a retort, the mercury air concentration in the hut would be 50 X higher than the occupational limit.

3. Outside in an open bowl
949,000 ng/m3 =  time-weighted average of breathing zone concentrations during two 8-hour work shifts for burners (Drake et al., 2001)
50,000,000 ng/m3/949,000 ng/m3 = 526.9
~ Burning amalgam outside rather than inside, even without a retort, reduces exposure by more than 500 times. However, this increases environmental contamination.

4. Outside in a retort
2000 ng/m3 = Air concentration during a burn with a retort at 1.5 m distance (personal communication, 2013)
949,000/2000 ng/m3 = 474.5
 ~ Using a retort reduces Hg air concentrations by 475 times when used outdoors, provided the retort is not opened until it is cool.

Historical and Modern Government Responses to Artisanal and Small Scale Gold Mining

Modified from: Telmer K. and Persaud A. (2013) Historical and Modern Government Responses to Artisanal and Small Scale Gold Mining. Rocky Mountain Mineral Law Foundation (RMMLF) and the International Bar Association, Special Institute on International Mining and Oil & Gas Law, Development, and Investment, Cartagena, Colombia, April 22-24, 2013.

Artisanal and Small Scale Gold Mining (ASGM) is an industry that has existed for millennia. But the most important periods (simply by production volume) are the two phases: (1) the 19th century gold rushes - roughly 1849 to 1929 (80 years), and (2) the modern ongoing gold rush – roughly 1970 to present with a big kick in 1980, (40 years and continuing). The earlier phase primarily took place in English or former English colonies described as “liberal democracies”[1] (US, Canada, Australia, New Zealand, and South Africa) and played a key role in the economic development and the evolution of governance systems in these countries. The modern gold rush is occurring more broadly geographically – in at least 70 countries – and in developing countries with a more diverse political history than those that were involved in the 19th century rush, but that have in common high rates of rural poverty.

A key similarity and driver behind ASGM for both the historical and modern context is the opportunity for relatively high incomes and conditions that allow laymen to directly participate in acquiring a share of the wealth – contrary to many rural agricultural opportunities. A key difference is how governments have responded. Government response to the earlier phase was characterized by support, provision of services, encouragement, and the development of laws and law enforcement mechanisms to protect and grow the sector towards “good behavior” congruent with the development of those emerging societies. Re-investment in the mining sector to support modernization and diversification was also a hallmark of the 19th century gold rushes. To a significant degree, the past behavior of those countries towards their historical informal mining sectors has led them to become the current leaders in the formal modern mining sector (referred to as the Large Scale Mining industry or LSM).

Government response towards the modern phase of ASGM has been dominantly characterized by marginalization, criminalization, and the attempted application of laws dominantly borrowed from the modern industrialized mining sector – laws that evolved out of the earlier gold rushes but that do not now easily support the development of the modern ASGM sector. The recognition that the modern ASGM sector will be a permanent feature of the modern mining industry for the foreseeable future and its important role in economic development is now firm[2]. It is recognized as a tremendous domestic development opportunity. However, today government response is still largely falling behind on actively developing the ASGM sector in a clear and robust manner. An indicator of this is the paucity of LSM-ASM collaborations. The lack of collaboration is not a technical one but often driven by complex legalities that leave the parties in a state of paralysis with respect to the rate of change possible to address key barriers. At this point in time we are 40 years into the modern gold rush. If it lasts 80 years like the 19th century rush, that leaves 40 years to have at least as good  an outcome. If that is to happen, legal reform will play a big role in providing the access to capital and technological upgrades that can create a small scale gold sector that can comply with modern mining and environmental codes and due diligence initiatives.

Gold production over the last 6000 years has been between 157,000 and 180,000 tonnes with about 80% of that remaining in existence and the balance lost in the sea[3],[4]. But 90% of all gold is estimated to have been produced since the California Gold rush in 1949 – the last 160 years. This was accomplished in 4 sub-cycles with 2001 theorized to be the year of peak gold production at 2,600 tonnes, according to a Hubert Style production cycle[5]. Analyses of the shape of the 4th and current sub-cycle predict 1,600 tonnes production in 2018 or 780 tonnes in 2026 for this 4th sub-cycle. Future smaller sub-cycles could occur but the total possible cumulative production is predicted to be between 230,000 and 280,000 tonnes, unless another supergiant goldfield like the Witwatersrand of South Africa is discovered4. However,, the role of ASGM has never been exclusively considered. They have existed before and will exist after most industrial mine sites. For example, many Latin American countries have communities that have been mining gold for 100 years, and with more modern approaches for 25 years, but a medium scale modern industrial mine may have a life expectancy of just 10 years in the same concession. So ASGM precedes and will outlast LSM in a significant number of concessions globally. This puts forth reasonable suspicion that an an unappreciated and poorly understood part of the earth’s gold endowment is the ASGM endowment. In some cases, ASGM can exploit deposits of just 100g per year – roughly $5000/y – still a fortune for many in the rural economies of the developing world.
“The numbers say that the last gold mine will be an artisanal gold mine”
Artisanal and Small-scale Gold Mining (ASGM) involves mineral extraction using manual labor and rudimentary tools. It requires low investment and little infrastructure. It may be a full time occupation, seasonal, or may provide a supplementary income. It can be a coping mechanism when other livelihoods fail or a preferential livelihood which surpasses other opportunities. Activities may fluctuate with commodity prices with high prices making mining more rewarding. Relative to developed world incomes, and incomes of the middle class in developing countries, incomes in ASGM are moderate to low for most individuals, but for those individuals, incomes are relatively high compared to alternatives. Frequently five times the value of alternatives. This is a transformative level of income growth according to Hans Rosling’s Dollar Street[6]
ASGM is a not simply a low capital method of mining but also an important gold supply chain and secondary economy. It is a gold-based socio-economic system that includes miners, security (police, military, and sometimes mafia), retail merchants, health providers, gold shops, gold refiners, financiers, claim holders, and many other service providers. Conservatively, the secondary economy around ASGM communities is five times the value of the gold produced. Globally, this amounts to about 100 billion dollars in 2012. The community that surrounds ASGM typically becomes increasingly entrenched, more sophisticated and grows in size and diversity over time, to include locals, foreigners, a multitude of institutes and businesses, national, regional, and local government officials, and others. An ASGM community can be formal, informal, legal, illegal, and extra-legal – a term used by Hernando de Soto[7] (The Mystery of Capital) in his discussion of informal economies where people cannot access capital because of missing information (he calls it dead capital) – essentially a lack of legal status or extra-legal.

While Gold mining in the developed world has shifted towards Large-Scale Mining (LSM) since the 1930s (the last 80 years), the industry and its champions was founded on the previous 80 years of Artisanal Mining from 1849 to 1929 in what Fetherling[8] calls the liberal democracies of the time (Canada, U.S., Australia, New Zealand, South Africa – with some caveats and an explanation of what happened in South Africa). In other words the modern mining industry was essentially launched by ASGM. How this “Early Modern Phase” – the 19th century gold rushes – effectively transitioned into a formalized, legal gold mining sector and how that compares to the “modern phase” of gold mining is an important question.

Modern ASGM
Modern ASGM essentially began once the gold standard was eliminated by President Nixon in 1971 and the price of gold skyrocketed from $35/oz to $800/oz in 8 years, peaking in early 1980 (see Figure 1). The initiation of the modern ASGM sector is perhaps marked by, and best exemplified by, the site of Serra Pelada (the naked Hill) in Brazil where perhaps 100,000 of the rural poor left their jobs on sugar cane plantations and worked square meter plots in a vast pit serviced by wooden ladders – it could be called a ground zero for the modern gold rush. 

Figure 1: Serra Pelada. Brazil, 1980
This cohort of miners then participated in leading the wave of artisanal gold mining in other parts of Brazil and in other countries in the Amazon basin over the next decades and until today. Serra Pelada was described as chaos but can also be viewed as a remarkable feat of rapid community self-organization in the absence of any significant government presence. Since then the modern ASGM sector has not stopped. Even through the relatively low gold prices in the 1990s, ASGM continued to flourish and is now, in part due to the elevated prices of gold that have been present since the 1970s and part due to the recent increase in gold price that occurred throughout the first decade of the 21st century. It is in an expansion phase and is providing a better opportunity for upward mobility than many alternatives in the developed world. More people are mining gold today than at any time in History. How this opportunity and its wealth are seized or squandered varies, and is another aspect that is shared with the 19th century gold rushes. How to make the best out of the artisanal gold sector’s opportunities is a priority area of focus for a growing number of intervention programs.  History provide us with some useful lessons.

Despite some of its significant negative impacts, ASGM is recognized as an extremely important rural livelihood[9],[10]. In gold alone, it is estimated that ASM employs 10 to 15 million people worldwide, and indirectly supports more than 100 million people. Conservative estimates suggest that artisanal and small-scale gold mining (ASGM) accounts for ~ 15% of the world’s gold production or about 400 tonnes per annum[11] however a recent estimate puts it as high as 25% of annual production[12]. Using 15% and 400 tonnes, the value of annual ASGM production for 2012 at the average price of $1670 USD/ozt is around US$ 21 billion. Because gold is so easy to valuate, the price obtained by miners in remote areas is rarely below 70% of the international spot price and often greater than 80%. ASGM therefore injects roughly 17 billion dollars directly into rural communities annually and this equates to about 100 billion when the secondary economy is considered. Due to demographic trends, continued growth in ASGM is likely.

ASGM injects roughly 20 billion dollars directly and 100 billion total into rural communities annually

Modern ASGM is often carried out informally or illegally and frequently occurs in association with activities such as tax evasion and smuggling, and sometimes can involve serious conflict[13]. There are a range of negative social and environmental impacts associated with ASGM including migration, family abandonment, substance abuse, sex trade, child labor, uncontrolled use of explosives, water pollution, deforestation, and uncontrolled and highly polluting mercury use. One of the key negative aspects of ASGM attracting international attention is the uncontrolled use of toxic mercury. Mercury amalgamation is currently the most commonly used method to extract gold in ASGM for a variety of reasons: it is a cheap, easy, quick, relatively effective recovery method which can be used by a single person in sites where there is little technology or infrastructure, capital investment is minimal compared to other methods and start up time can be days rather than years. Mercury is usually very easily purchased and is relatively cheap (around 0.1% of revenue from the gold produced); and miners often do not know about the health effects, alternatives, nor have the capital to invest in them.

ASGM is now recognized as the single largest source of anthropogenic mercury released to the environment in the world surpassing coal[14]. UNEP (2013 Global Mercury Assessment) estimates that ASGM released roughly 1,600 tonnes of mercury to the environment in 2012, with 45% of that going directly to the atmosphere and the remainder entering local waterways and soils where it may be later released or cause persistent contamination for centuries. The different ways in which mercury is used leads to a variety of intensities of mercury use per unit of gold produced. One mercury intensive worst practice is called whole ore amalgamation where 100% of the ore mined is brought into contact with mercury.  Another is when mercury contaminated materials are subsequently treated with cyanide – this is done to extract more gold but also re-mobilizes the mercury in more toxic forms into the environment. The text of the Minamata Convention on Mercury, which was adopted by delegates from over 140 countries on January 19, 2013, recognizes these as worst practices.

This Convention aims to have significant impacts on the availability, trade, use and discharge of mercury worldwide. The Convention calls for the preparation and implementation of National Action Plans (NAP) (Article 7) and outlines the mandatory and recommended measures that a NAP must contain (Appendix on ASGM). One recommended measure to reduce and where feasible eliminate mercury is to formalize ASGM through access to training, credit and cleaner technologies. This is included in the treaty because it is recognized that without alternative practices, the instrument could criminalize miners forcing them to buy mercury in illegal markets and leaving them even more vulnerable to criminal networks that control parts of the mercury and gold trade.

The same unintended consequences are recognized by the proponents of those parts of the Dodd Frank Act (Section 1502) that requires guarantees that minerals exported from the DRC are not funding armed conflict, and the Due Diligence Guidance developed and adopted by the OECD[15] for tin, tantalum, tungsten, and gold produced in areas of conflict or “high risk”. The definition of “high risk” used by the OECD is currently being finalized by the Geneva Academy but the working definition that has been used in 2012 places most ASGM communities in the world in a situation where adequate due diligence will be required in order for them to participate in the formal gold supply chain. Somewhat obviously, they are the least able to comply setting up either the largest formalization process in gold in centuries or a growing black market or other impacts.

Although this is by no means an exhaustive description, it is clear artisanal and small scale gold mining in the modern world, although it is practiced in the field in almost the same manner as it was historically, has become vastly more complicated beyond the field level (downstream). A comparison of the outcomes of the 19th century gold rush and the trajectory of the current one, suggest that in order to have at least as good an outcome (or an even better one), there will need to be innovation, assistance, and a continuing change of policy from governments and the private sector in order for artisanal miners to use the wealth they generate for development as it was used in the 19th century rushes.

Historical ASGM
The 19th century gold rushes began essentially with the California rush in 1849, and continued until 1929 with ups and downs in the U.S., Canada, Australia, New Zealand, and South Africa. By the late 19th century there was already a pattern in all of these countries, of Artisanal and Small-Scale miners grouping into larger companies[16]. The gradual shift into larger, organized groups of miners and eventual industrialization came both as a response to organizational and technological necessity and government policies. In Australia in the late 1800’s for example, the need to pool resources in order to purchase modern equipment led to increased levels of organization and industrialization and this was paralleled by higher licensing fees.[17]

To varying degree legal reforms surrounding the ASGM sector in the 19th century both followed and drove its development, organization, and growth. The first comprehensive mining law passed in the U.S. in 1866 favoured larger groupings of miners or corporations,[18] and by doing so implicitly nudged the sector and individual miners towards formalization and growth. However, the miners were already, to a large degree, organized, and were formalized within an informal framework that they were running. The reason that the 1866 General Mining Law in the U.S. was successful was that even though it supported industrialization and larger groupings of miners, it was also designed to support and strengthen the extra legal arrangements and contracts that were already in place and had been negotiated over the last 20 or so years by informal ASGM miners.[19]

In order to drive investment and industrialization of the mining sector, the government needed to create a uniform set of rules and clear legal assurances to capitalists, but any statute needed also to take into account the extra legal contracts already formed by miners for it to be functional and respected. In 1861, in the case of Gore V. Breyer a Justice of the California Supreme Court upheld the legitimacy of ASGM miner’s extra legal arrangements.[20]

Past V. Present
In comparing the 19th century gold rushes to those of today one obvious difference is that they occurred when there was little to no industrial gold mining in the “new world” whereas present day ASGM is occurring alongside a very well developed industrial gold sector which has mature governance systems, ones that may have grown out of the historical gold rushes but that are now distant from those roots and employed for very different circumstances and conditions. Elements like massive capital investment, lengthy negotiations, highly educated personnel and long time-scales to bring mines from discovery to production are the norm for the modern industrial gold mining sector. These modern systems are simply not feasible for ASGM which has little access to capital and a great need to generate income on a very immediate basis. But developed countries have not looked to the roots of their domestic mining acitivities as much as they have the strict governance regimes of the developing countries.  Essentially the developing countries have tried to leapfrog the development context that occurred during the 19th century and this has unintentionally caused a significant barrier for ASGM to evolve capacities and systems that would allow them to easily be a formal part of the modern mining sector.

Mining codes for countries such as Senegal, Mali, Burkina Faso, Ghana, and others, do now include adaptations to include ASGM but in most cases these did not naturally grow out of the small scale sector but rather have been inserted as remedial measures to make up for the gaps that are recognized. No attempts were made in 19th century rushes to limit the scale of the mining, rather the opposite, it was encouraged and capital brought in to upscale and industrialize it and this happened in concert with the increased regulation, formalization, and governance.

Therefore the current dilemma is to increase regulation, formalization, and governance without limiting the development opportunity but also with limitations on the scope of sector that recognizes new criteria like ecosystem integrity.

Canada, circa 1890

Brazil, circa 1990
Both then and now governments are encouraging ASGM miners to organize into larger groups and formalize, but the difference lies in the steps being taken to make this happen. Governments of the 19th century quickly recognized that hard-handed approaches and top down bureaucratic requirements were not functional for the hundreds of thousands of extra legal ASGM miners[21]. They therefore took the steps to incorporate pre-existing extra legal arrangements and contracts into formal legal code, while at the same time provided important services to support the formalization and development of the sector. Infrastructure was developed such as railways, and police were often deployed to ensure the safety and security of miners (water rationing, adequate supplies). In New Zealand the government played the role of ensuring that service providers, such as supply trains, were not extorting miners.[22] These essentially were expansionist policies to grow a more equitable and sustainable sector. 

In the 19th century ASGM, the government experimented with different ways of gaining from gold mining, as much as possible without hampering the rights and inherent individual economic liberalism that the activity represented. In order to control the sector, in places like Australia, licensing fees were put into place, which quickly became a common source of conflict between miners and governments. Duties and royalties also were a way for government to benefit from and control the mining, but it took various attempts and many miner upheavals for governments to find the right balance.[23] Taxes on gold in Canada were not introduced until 1897, starting at 20% of all gold produced. This rate was quickly reduced to 10% with a $5000 dollar exemption as a result of protest and a rapid growth in the informal supply chain.[24] At the Klondike it was believed that only 1 in every 10 ounces were being declared officially due to high royalty fees on production.[25] Today, in a country like Burkina Faso, it is estimated that 1 in every 45 ounces are declared officially, for much the same reasons. Various solutions were attempted, one approach was a tax at the point of export rather than at the point of production (Ibid.,62), a policy designed to assist miners in the field while limiting capital flight. However, this was also recognized as only partially successful at best and ultimately these policies evolved towards those in practice today in countries like Canada – a free market for gold, negotiated royalties, corporate taxes, and increased tax revenues for governments from the secondary economy that surrounds mining. In the context of ASM if this model is applied, tax revenues would predominantly come from the last category – the secondary economy.

Governments of the 19th century, aware that the only way of mitigating losses would be formalization, took the necessary steps to make that happen. In large part, this meant reducing or eliminating the bureaucratic impediments to licensing and formalization. By 1899 in the Klondike for example, steps were taken to reduce corruption and preferential treatment surrounding the filing of claims in the office of the recorder[26]. The formalization processes for ASGM miners today in many developing countries have largely failed to learn from this past experience. In Senegal for example, the fee to register an artisanal concession costs approximately $3000 USD - a price far out of the reach of most ASGM miners in Senegal. The costs to legally buy or sell gold in Burkina Faso can be more than $20, 000 USD[27].

An idea of the complexity of formalizing an informal mining operation can be at least partially understood by looking at other sectors where similar investigations of informal economies have been undertaken. In the Philippines, for example, the procedure to formalize urban property (an informal shack in an urban slum) takes 168 steps and between 16-25 years.[28] Currently, in the departmento of Arequipa, Peru, it is estimated that if half of registered ASGM miners (which are a smaller subset of the real total) were to go forward with the recommended procedures to formalize, the government would require three years to process them. Few are willing or capable of waiting that long. 

Lurking Paradox
While the 19th century governments were able to recognize the importance of the sector for economic growth and diversification and subsequently evolve and develop the ASGM sector into a thriving, formalized, industrial sector by involving the miners and their innovations in policy reform, the modern phase has been dominantly paralyzed by a top down approach that attempts to impose a foreign system of strict mining codes on the ASGM sector without recognizing the value of the functional system that already exists within the sector. This is not surprising with the ASGM superimposed on what is viewed as a more desirable highly formalized and developed LSM sector. It is difficult for governments in developing countries to recognize the value of the ASGM sector when it is mostly informal, undocumented, shrouded and poorly understood, and therefore in stark contrast to the LSM sector. Governments may look to the successful Western economies as examples, and see large scale industrialization as a key to development. It is undoubtedly a part of it. However, it is worth reflecting upon that the industrialized mining sectors of Western economies today were a gradual outgrowth of a thriving ASGM sector in the past.

When technological capacities, legal conditions including environmental rules and due diligence requirements, are considered, one possible logical pathway for the evolution of the ASGM sector will be to register and improve productivity with cheap high efficiency gravimetric systems – chemical free – combined with a tailings collection and processing system, one that is more centralized so that it can meet the very high environmental standards of cyanide use – like the LSM sector. A so called “win win” situation. The legal process however needs to work on policy that would allow this type of synergy to occur by lowering barriers for LSM-ASM cooperation to occur. Peaceful collaboration with the ASGM community should lower a company’s risk register. The IFC published a tool to evaluate the net present value of a sustainability investment and showed it to be profitable on short time scales[29].
