Black Pine (formerly called Mineral Gulch) is a Carlin-style, sediment-hosted gold property located in Cassia County, southern Idaho. It is host to a past-producing heap leach gold mine that operated from 1991 through 1998. During this time, it produced approximately 435,000 ounces of gold at a historical grade of 0.7 grams per tonne from seven shallow pits.
In June 2016, Liberty Gold acquired the Black Pine Property from Western Pacific Resource Corporation for US$800,000 cash, 300,000 shares of Liberty Gold and a 0.5% NSR reserved to Western Pacific. At present, the project consists of 345 federal lode claims (26.3 km2).
There are 1866 historic shallow (most averaged only 96 m in length) drill holes on the property and a larger number have unmined oxide gold intercepts including:
- 12.2m grading 1.24 g/t Au and 6.1m grading 0.48 g/t Au
- 24.4m grading 1.59 g/t Au
- 4.6m grading 2.17 g/t Au and 10.7m grading 2.60 g/t Au
Oxide gold is present in historic drill holes, pit walls and outcrop samples and extensive grid soil surveys. The large mineralized footprint covers a 12km2 area, which will be the priority exploration target for Liberty Gold.
Mineralization consists of finely disseminated gold hosted in Pennsylvanian decalcified and jasperoidized calcareous siltstone correlative with the Oquirrh Formation. These rocks are present within a system of interleaved, low-angle thrust faults that is well-exposed in many parts of the property. In other areas, the prospective host horizon is believed to be present under the shallow cover of an overlying thrust plate; these areas are significantly underexplored.
