Excelsior Mining Completes Hydrology Pump Tests

Excelsior Mining (TSXV:MIN) has completed feasibility level hydrological test work at its Gunnison project in Arizona.

As quoted in the press release:

A total of 26 hydrological test wells, totalling 25,870 feet of drilling, were used in the current hydrological test program. The holes were drilled in various locations around the North Star deposit, representing a variety of fractured zones, rock types and mineralized areas. Of the 26 holes drilled, 18 were pump test holes and 8 were observation holes. The pump test holes were pumped for approximately five days and were surrounded by the new observation wells and by numerous pre-existing observation wells. In all, approximately 65 observation wells were monitored during the pump testing, generating a comprehensive high quality data set.

The data collected from this program will be used to characterize the various groundwater properties that determine the movement of fluids through the mineralized bedrock. This information will be used to produce 3D hydro-geological models for requisite permit applications and the bankable feasibility study. The 3D hydro-geological models will simulate the planned in-situ recovery process and demonstrate hydraulic control during mining operations. Excelsior management expects the results of all testing, and 3D models will be completed by early Q3. Excelsior will issue a press release when this work is fully complete.

Excelsior president and CEO, Stephen Twyerould, said:

The successful conclusion of our hydrological test program, on time and on budget, demonstrates our ability to run complex technical work programs with optimal efficiency. We look forward to releasing the results of our test work and 3D hydrological modelling and moving the Gunnison Project a significant step closer to commercial production.
