"The last exploration program underground at the Carolin "The last exploration program underground at the Carolin was a drill program completed between 1994 -1996 by Athabaska Minerals who planned to take the mine back in production, but falling gold prices prevented them from executing the plan. The Company commissioned a 3D geological model in late 2014 utilizing all available data from the combined $3.5M Athabaska drill program and historical drill data that led to the development of the Carolin Mine. With the collective historical drill data and critical new data from underground surveys, mapping and sampling, the Company will be able to complete the 3D geological models, which will not only assist in constraining the existing Carolin resource, but serve as an effective guide for the upcoming drill program and for future exploration programs".
