Excelsior Mining Corp. (TSXV:MIN) has commenced its hydrological drilling program at the Gunnison Copper Project, located in Arizona.

As quoted in the press release:

The primary component of the hydrological program will comprise 26 hydrology test wells totalling approximately 28,000 feet. Extensive geophysical logging and long term pump tests will be conducted on all holes with the objective of characterizing aquifer properties and the variations that control the movement of fluids through the mineralized bedrock. Because hydraulic conductivity, effective porosity, and aquifer continuity are critical in the mining process, the investigations of potential conduits or barriers to groundwater flow will prove invaluable to the ultimate design and success of the production well field. Results will be used to construct a numerical groundwater flow and transport model to simulate the planned in-situ recovery operations, and to demonstrate hydraulic control during operations. Additional long-term aquifer testing will also be conducted on previously constructed wells.

Excelsior president and CEO, Stephen Twyerould, said:

The economic advantages of the Gunnison Project are based largely upon the hydrology elements that define the project. The results of the hydrological program will represent the largest and perhaps the most important component of our feasibility study. We look forward to reaffirming that the conditions at Gunnison are optimal for safe and effective in-situ recovery copper mining.
