Life Cycle of a Mine: From Planning to Rehabilitation

View the full-size infographic by clicking here.

Mining provides the critical minerals and metals needed for modern society to function. However, if these resources are not properly managed, mining activity can impact local environments and biodiversity.

For this reason, the mines of today prepare for a rehabilitated landscape right from the beginning, in a process known as “progressive reclamation”.

Today’s infographic comes to us from Natural Resources Canada, a government entity which funded the development of the Canadian Minerals and Metals Plan that supports sustainable mining practices throughout its lifecycle.

What is Progressive Mine Reclamation?

The process of progressive reclamation, also known as rehabilitation, plans for post-closure activities during the mining process, from before the first bit of dirt is moved to when the last truck leaves the mine.

There are three stages to the mining process, each with their own associated activities to plan for mine reclamation.

  1. Before Mining: Integrated mine planning for closure and reclamation
  2. During Mining: Planning for climate change impacts and land use
  3. After Mining: Closure and reclamation

While these are distinct stages, three continuous processes occur throughout the sequence of the mining life cycle:

  • Continuous monitoring
  • Continuous engagement with Indigenous Peoples, communities, and regulators
  • Continuous updates to ensure closure and reclamation plans complement any modifications to the mine plan

  • Each process is meant to be inclusive, continuous, and responsive to the constantly changing environment to ensure there is flexibility and preparedness to adapt as necessary.

    1. Before Mining

    The rehabilitation process starts before mining begins. The permitting process for mine development requires closure and reclamation plans.

    2. During Mining

    An area of the mine can be reclaimed even as other parts of the mine are in operation. Mitigating the impacts of land disturbance during operations are critical to return the land to a viable state.

    Climate change impacts can affect operations, and mine operators should account for this in ongoing processes to ensure successful closure and reclamation.

    Water treatment facilities process surface and mine waters to ensure compliance, water recycling, and watershed management. This is all under the eye of continuous monitoring of the movement of earth and materials.

    3. After Mining

    Once the mining process is complete, mining companies can return the land to a natural state and prepare for post-closure reuse. Mine closure and rehabilitation activities need to take local environmental conditions into account. Evidence of the mining operation must be removed as much as possible.

    Part of this process means the continued relationship with the people, community, and lands affected. Mining companies can re-purpose for other uses, including:

    • Agriculture
    • Solar panel farms
    • Biofuel production
    • Recreational and tourist use

    By incorporating local and traditional knowledge into planning and working with Indigenous Peoples and communities, modern practices and local knowledge can restore the land in a way that also brings benefits to the local community.

    The Canadian Minerals and Metals Plan

    Mining operations can generate opportunities for new businesses to create local benefits. Reverting mines to a rehabilitated state will ensure that the landscape can continue to support life for centuries to come.

    The Canadian Minerals and Metals Plan supports this vision of progressive mine rehabilitation, to ensure Canada remains a responsible mining powerhouse for generations to come.

Expanding the Cannabis Consumer Base with Odourless Products

This infographic explores the stigma that surrounds cannabis consumption, and a new technology that could provide a promising solution.

Expanding the Cannabis Consumer Base

The prohibition of cannabis is lifting around the world, and millions of consumers are pushing the market to exceed $75 billion by 2025, from $13 billion in 2019.

As awareness grows, more information about the health benefits of cannabis drives consumer interest, but there’s one problem. The smell of cannabis products—particularly when smoking flower—deters both current and potential cannabis consumers.

Today’s graphic from CannabCo explores the social stigma that clouds the cannabis industry and introduces a new technology that could provide a disruptive solution.

The Pressures of Social Stigma

The lingering stigma that surrounds cannabis consumption has existed for decades, limiting the number of recreational and medical users.

Although numerous dimensions of this stigma exists, two of them are particularly prominent and damaging to consumers:

  • Cannabis is addictive: Being negatively labelled as a drug addict, stoner, or “pothead”, personas which are associated with criminal activity.
  • Cannabis is an identity: Smokers have difficulty concealing their consumption, as the smell can cling to the user and become part of their identity.

This intrusive and long-lasting odour is a distinctive and often unwanted aspect of smoking cannabis. Despite great strides being made to change perceptions about the industry, the odour continues to fuel the stigma.

Where Does the Smell Come From?

The odour comes from chemicals found in the plant, known as terpenes. They produce aromatic oils that give cannabis strains a unique scent—such as lemon, pine, or even coffee—and have been used for thousands of years in traditional herb-based medicine.

Terpenes and cannabinoids work together to multiply the plant’s medicinal properties, in a process known as the entourage effect. Of course, this is a double-edged sword, as new users are attracted to the medicinal benefits of cannabis, but are deterred by the smell, harsh burn, headaches, and coughing that comes with inhaling it.

The Path to a Cleaner Cannabis

Aside from the pain points that arise from smoking, there is also a need to combat the smell of cannabis products when they are stored. Therefore, an odourless cannabis could potentially reach an entirely new group of consumers who are deterred by the smell, and provide peace of mind for existing consumers.

CannabCo has developed a breakthrough technology, called PURECANN™, which creates a purer form of cannabis by eliminating the smell and harshness. It also creates a wealth of associated benefits:

  • Virtually undetectable odour of stored dry product.
  • Undetectable odour while smoking in public.
  • No third-party gadgets or devices required by the user.
  • Less residual “day-after effect” associated with smoking cannabis.

The unique technology removes the plant’s aroma, without compromising any of its medical properties. Moreover, it also benefits non-smokers who do not want to smell second-hand smoke.

Opening the Floodgates

While smoking cannabis is not something to be ashamed of, the PURECANN™ technology can provide users with the option of smoking more discreetly.

CannabCo dedicates itself to using new technologies to enhance the way people consume cannabis, and its most recent creation has enormous potential.

By providing a cleaner product, the cannabis experience could become more tolerable and accessible. As a result, the heavily stigmatized industry could drastically transform—and convince millions of new consumers to take notice.

Gold in the Abitibi: The Chimo Mine Project

Cartier Resources (TSX-V: ECR) is advancing the Chimo Mine Gold Project in the Abitibi region of Quebec, showing its potential with past producing mines.

Gold in the Abitibi: Cartier Resource's Chimo Mine Project

Gold in the Abitibi: Cartier Resources Chimo Mine Project

Cartier Resources (TSX-V: ECR) is deploying the right strategy in the right region, with the right backers to find gold faster at a lower cost.

Proven Endowment: The Abitibi Greenstone Belt

There are many prolific past-producing gold districts in Canada, but the Abitibi is one of the largest and best understood gold-bearing regions with readily available exploration infrastructure.

This region extends from Wawa in Northwestern Ontario to the east near Val-d’Or Quebec – a landscape that hosts some of the most productive gold mines in Canada.

The company’s Chimo gold mine project located in the historic Abitibi Greenstone belt of Quebec builds on a legacy of gold production with a project ready for investors.

Exploration Strategy

The best place to find gold is where companies discovered and mined it in the past. Between 1964 and 1997, three companies produced 379,012 ounces of gold at the Chimo Mine property.

This type of strategy is known as brownfield exploration. Brownfield exploration looks for gold in areas known to host gold mineralization. It offers investors less risk, reducing the amount of uncertainties a company faces.

Ounces in the Ground: 2019 Resource Estimate

The company delivered within three years its first-ever resource estimate and proved the value its Chimo Mine Project. In November 2019, Cartier published its first mineral resource estimate of the central gold corridor on the Chimo mine property:

Measured Resources: 481,280 ounces of gold
Inferred Resources: 417,250 ounces of gold

Cartier has proven a resource in one third of the Chimo property, and there is the north and south gold corridor which it is currently drilling.

Why Chimo?

Cartier Resources has built on the foundations of a proven past producer with a new resource estimate, to put the Chimo Mine project back on the Abitibi gold map.
