Don't forget the marshmellows!“Unprecedented forest fire outbreak in Quebec forced shut downs at several mining operations in the province, noted Kitco correspondent Paul Harris. Several miners, developers and juniors suspended operations due to operating hazards in Quebec. Wesdome Gold Mines (TSX: WDO) announced yesterday that it temporarily suspended underground activities and surface exploration activities at the Kiena Mine in Val d’Or, Quebec. Earlier in the month Hecla Mining (NYSE: HL) suspended operations at its Casa Berardi mine.

What we know for sure:
Desiccation of the Global Arboreal Forest will become much worse.
How do we know this:
Forests now exist in biomes where higher temperatures dry out the vegetation, weakens trees and promotes bark beetle infestation. Stands of dead or dying conifers from beetle attack allow fires to reach tree crown thereby creating mega-fire storms that burn so hot as to actually change the chemical makeup of the hillside soil. These changes create a waxy material in the soil that is water repellent, so that subsequent precipitation runs off, frequently causes flash floods and mud or landslides.
Here’s the important part: The threat from hydrophobic soils can last for years, and every burn scar is a potential disaster. Mining investors must consider the many risks involved with an operation of a mine, but going forward one also needs to ask: - How far is it to the Sea?
- Does the route pass through mountainous terrain?
- What is the level of civil engineering and construction standards in the region?
- Does the country have the necessary resources to maintain and repair road/rail systems?
Why is hydrophobicity important? Fire induced water repellency can affect the soil and the watershed in the following ways:
• Hydrophobic soils repel water, reducing the amount of water infiltrating the soil.
• Decreased soil infiltration results in increased overland and stream flow.
• Erosion increases with greater amounts of runoff and fertile topsoil can be lost.
• Increased runoff carries large amounts of sediments that can clog stream channels and lower water quality.
• Depending on the intensity of the fire, hydrophobic layers can persist for years, especially if they are
thick
