Visualizing the Life Cycle of a Mineral Discovery

Mining legend Pierre Lassonde knows a little bit about mineral exploration, discovery, and development. Drawing from decades of his experience, he created the chart above that has become a staple in the mining industry—the Lassonde Curve.

Today’s chart of the Lassonde Curve outlines the life of mining companies from exploration to production, and highlights the work and market value associated with each stage. This helps speculative investors understand the mining process, and time their investments properly.

Making Cents of Miners: The Stages of a Mineral Discovery

In the life cycle of a mineral deposit, there are seven stages that each offer specific risks and rewards. As a company proves there is a mineable deposit in the ground, more value is created for shareholders along the way.

  1. Concept

    This stage carries the most risk which accounts for its low value. In the beginning, there is little knowledge of what actually lies beneath the Earth’s surface.

    At this stage, geologists are putting to the test a theory about where metal deposits are. They will survey the land using geochemical and sampling techniques to improve the confidence of this theory. Once this is complete, they can move onto more extensive exploration.

  2. Pre-Discovery

    There is still plenty of risk, but this is where speculation hype begins. As the drill bit meets the ground, mineral exploration geologists develop their knowledge of what lies beneath the Earth’s crust to assess mineral potential.

    Mineral exploration involves retrieving a cross-section (drill core) of the crust, and then analyzing it for mineral content. A drill core containing sufficient amounts of metals can encourage further exploration, which may lead to the discovery of a mineable deposit.

  3. Discovery

    Discovery is the reward stage for early speculators. Exploration has revealed that there is a significant amount of material to be mined, and it warrants further study to prove that mining would be feasible. Most speculators exit here, as the next stage creates a new set of risks, such as profitability, construction, and financing.

  4. Feasibility

    This is an important milestone for a mineral discovery. Studies conducted during this stage may demonstrate the deposit’s potential to become a profitable mine.

    Institutional and strategic investors can then use these studies to evaluate whether they want to advance this project. Speculators often invest during this time, known as the “Orphan Period”, while uncertainty about the project lingers.

  5. Development

    Development is a rare moment, and most mineral deposits never make it to this stage. At this point, the company puts together a production plan for the mine.

    First, they must secure funding and build an operational team. If a company can secure funding for development, investors can see the potential of revenue from mining. However, risks still persist in the form of construction, budget, and timelines.

  6. Startup/Production

    Investors who have held their investment until this point can pat themselves on the back—this is a rare moment for a mineral discovery. The company is now processing ore and generating revenue.

    Investment analysts will re-rate this deposit, to help it attract more attention from institutional investors and the general public. Meanwhile, existing investors can choose to exit here or wait for potential increases in revenues and dividends.

  7. Depletion

    Nothing lasts forever, especially scarce mineral resources. Unless, there are more deposits nearby, most mines are eventually depleted. With it, so does the value of the company. Investors should be looking for an exit as operations wind down.

Case Study: The Oyu Tolgoi Copper-Gold Discovery, Mongolia

So now that you know the theoretical value cycle of a mineral discovery, how does it pan out in reality? The Oyu Tolgoi copper deposit is one recent discovery that has gone through this value cycle. It exemplifies some of these events and their effects on the share price of a company.

    1. Concept: 15+ Years

      Prospectors conducted early exploration work in the 1980s near where Oyu Tolgoi would be discovered. It was not until 1996 that Australian miner BHP conducted further exploration.

      But after 21 drill holes, the company lost interest and optioned the property to mining entrepreneur Robert Friedland and his company Ivanhoe Mines. At this point in 1999, shares in Ivanhoe were a gamble.

    2. Pre-Discovery/Discovery: ~3 years

      Ivanhoe Mines and BHP entered into an earn-in agreement, in which Ivanhoe gained ownership by completing work to explore Oyu Tolgoi. A year later, the first drill results came out of drill hole 150 with a headline result of 508 meters of 1.1 g/t Au and 0.8%. To get a sense of how large this is, imagine the height a 45-story building, of which a third of story is copper. This was just one intersection of an area that could stretch for miles.

      Wild speculation began at this stage, as steadily improving drill results proved a massive copper-gold deposit in Mongolia and drove up the share price of Ivanhoe.

    3. Feasibility/Orphan Period: ~2 years

      In 2004, the drilling results contributed to the development of the first scoping study. This study offered a preliminary understanding of the project’s economics.

      Using this study, the company needed to secure enough money to build a mine to extract the valuable ore. It was not until two years later, when Ivanhoe Mines entered into an agreement with major mining company Rio Tinto, that a production decision was finalized.

    4. Development: 7 years

      By 2006, the Oyu Tolgoi mineral deposit was in the development phase with the first shaft headframe, hoisting frame, and associated infrastructure completed. It took another two years for the shaft to reach a depth of 1,385 feet.

      Further development work delineated a resource of 1.2 billion pounds of copper, 650,000 ounces of gold, and 3 million ounces of silver. This first stage of development for Oyu Tolgoi made Mongolia the world’s fastest growing economy from 2009 to 2011.

    5. Startup/Production: Ongoing

      On January 31, 2013, the company announced it had produced the first copper-gold concentrate from Oyu Tolgoi. Six months later, the company stated that it was processing up to 70,000 tonnes of ore daily.

    6. Depletion: Into the Future

      The Oyu Tolgoi deposit will last generations, so we have yet to see how this will affect the value of the mine from an investment perspective.

      It’s also worth noting there are still other risks ahead. These risks can include labor disruptions, mining method problems, or commodity price movement. Investors will have to consider these additional conditions as they pan out.

The More You Know

Mining is one of the riskiest investments with many risks to consider at every stage.

While most mineral discoveries do not match it perfectly, the Lassonde Curve guides an investor through what to expect at each stage, and empowers them to time their investments right.

Visualizing Mining’s Footprint in British Columbia

Mining represents 7% of British Columbia’s GDP despite only accounting for 0.04% of the land use.

Mining Footprint in British Columbia

Visualizing Mining’s Footprint in British Columbia

British Columbia is considered a global leader in the development of socially and environmentally responsible resources.

An estimated 54% of the province’s total land is protected, making it one of the world’s greenest mining hubs.

This graphic by the B.C. Regional Mining Alliance (BCRMA) details mining’s footprint in the province.

A Tier 1 Jurisdiction for Mining

British Columbia covers almost 95 million hectares (234 million acres), more than any European country except Russia, and more than any U.S. state except Alaska.

As the largest mining province in Canada, BC registered $18 billion in revenue from the industry in 2022.

British Columbia stands as Canada’s sole producer of molybdenum, which finds applications in metallurgy and chemistry. Additionally, B.C. is the country’s leader producer of copper and steelmaking coal, besides gold and silver.

B.C. mined material breakdown

At the heart of British Columbia’s mining industry lies the Golden Triangle, one of the hottest mineral exploration districts in the world.

More than 150 mines have operated in the area since prospectors first arrived at the end of the 19th century. The region alone is endowed with minerals worth more than $800 billion.

How Green is B.C. Mining

Mining represents 7% of the province’s Gross Domestic Product (GDP), despite only accounting for 0.04% of the land use. In comparison, farmland demands 3% of the land, bringing $2.1 billion (0.8%) per year.

Land Use in B.C.Revenue (2022, CAD $)
Mining 0.04%$18.0 billion
Oil & Gas 0.4%$9.5 billion
Infrastructure1%$25.0 billion
Farmland3%$2.1 billion
Forest62%$13.3 billion

Mining operations are also supported by a stable, transparent, and effective policy environment. The province ranked as the world’s least risky for mining in 2017 and 2018.

In addition, mineral exploration has received ample support from local Indigenous communities. Today, mining accounts for over two-thirds of all indigenous people employed in the extractives sector.

According to the International Energy Agency, up to six times more minerals and metals will be needed by 2040 to accelerate the energy transition.

In this scenario, British Columbia is well positioned to support the transition to a low-carbon future and make a significant contribution to climate action.

The BCRMA is a strategic partnership between indigenous groups, industry, and government representatives that aims to promote B.C.’s mining opportunities internationally.

Ranked: The Largest Undeveloped Silver Deposits in the World

Global silver demand is poised to soar in the next decade, driven by emerging technologies like electric vehicles and solar power.

Silver demand from solar alone has grown from less than 50 million ounces (Moz) a decade ago to an expected 160 Moz in 2023.

So, where will the necessary supply come from to meet this surge? This graphic from Discovery Silver shows the largest undeveloped silver deposits in the world.

Silver in Green Technology

Silver is a vital part of solar cells. The metal is converted into paste and coated onto silicon wafers to make solar arrays.

When sunlight hits the silicon, silver helps to transport the generated electricity for immediate use or store it in batteries. A typical solar panel can contain as much as 20 grams of silver.

Silver’s conductivity and corrosion resistance are vital in electronics, especially electric vehicles where nearly all electrical connections rely on the metal. Over 50 million ounces of silver are used every year to enhance conductivity in powered seats, windows, and other vehicle electronics.

In 2022, 27% of all silver consumption in the U.S. was attributed to electrical and electronics, while 10% was linked to solar technology.

Global Silver Demand Rising

With the increasing demand for new technologies combined with physical investment (bars) demand, the silver market saw a 237.7 Moz deficit in 2022, an all-time record.

2023 silver industrial demand is forecasted to rise by 4% to a new record high.

However, according to the Silver Institute, mined output is expected to decline over the next five years.

In this scenario, new mines are expected to play an important role in meeting the demand.

Currently, the world’s top 10 undeveloped silver deposits contain 984 Moz. Discovery Silver’s Cordero project in Mexico leads the ranking:

Cordero is located in Chihuahua State in Mexico, one of the world’s most prolific silver producing regions.

Once in production, it is expected to become one of the top three silver mines in the world.
