2. As they depend on non-renewable resources and complex geopolitical factors, mining operations require a forward-looking approach to survive. Here Roman Rubin Black Tusk explaining how the industry is turning to more sustainable practices over the long term. The mining industry was radically different just a few decades ago. Of course, non-renewable resources have always been exploited here, but our technologies, our practices and our environmental knowledge have undergone profound changes in a short time.

3. Mining geology must preserve the Earth’s resources, and mining operations must be as sustainable as possible to protect our future. Industry professionals are encouraged by the remarkable advances we have made in operational practices over the past few decades. Here are six innovative ways the mining sector has adopted to foster a more environmentally and financially sustainable future. The mining sector is a relatively risky business activity where capital expenditure and approval of large new projects are limited*. However, with a strong business sense, financially and strategically, much more can be done with less. Black Tusk Maximize Value, Reduce Waste Just as important as business acumen, efficiency makes a difference in the viability and success of a mining operation. In addition to extracting non-renewable resources like minerals, mines also exploit large amounts of energy, water and soil resources. By adopting a dual approach* which consists in reducing both inputs (by diverting

4. surface water, pumping groundwater or using other sources of energy, solar or wind, for example) and outputs (by using cleaner production techniques and reusing mine wastes and by-products), the efficiency and sustainability of mining operations can be maximized. Mines Without the Carbon Footprint Mining operations, especially those that extract coal, were at the top of the list. Fortunately, the activities of mining companies are changing today. These significantly reduce their carbon footprint and make their operations more environmentally friendly. Here are some of the new trends that have become common in zero-carbon in Roman Rubin mining projects: •use of mobile electric vehicles to reduce fuel consumption and improve atmospheric quality; •remote controlled activities: mobile mining equipment is operated from the surface (which goes in the direction of a zero accident * approach in mining companies); •use of variable speed fans to limit energy consumption; •use of intelligent tracking technology to optimize ventilation and fleet management activities;

5. •optimization of extraction methods to reduce the amount of waste produced. Close and Rehabilitate Mining Sites If mine sites are not properly closed and then rehabilitated, they can pose great dangers to their immediate environment. Noxious waste can be found on the site, which would cause contamination of the land and water, in addition to harming people and animals around. The easiest way to shut down and rehabilitate a mine is to limit the disruption it can cause from the start. Site selection plays a big role in this, as does the adoption of sustainable mining practices discussed above. It is also financially more viable to plan well from the outset for the closure and rehabilitation of the mine, as this greatly reduces the costs associated with guarantees regarding its closure plan. Apply a Circular Economy Approach Roman Rubin Black Tusk Resources talks about the importance of reducing mining waste. However, despite our best efforts, mining activities will always produce

6. residues and by-products. What if we could turn these materials into reusable, financially viable assets rather than storing or throwing them away? By taking a circular economy approach, many mining companies are finding innovative ways to extend the life cycle of materials that previously would have been considered waste. Each of these six ways will enable mining companies to shape a more sustainable future, both fiscally and environmentally. And now is more than ever a good time. To conclude, the global trend towards a green economy will promote growth in the mining sector, as demand for metals and minerals will be strong. For example, Canada has rich deposits of minerals prized for renewable energy technologies, which allow profitable mining projects.
