[{"type":"text","content":" TORONTO, Nov. 28, 2018 (GLOBE NEWSWIRE) -- Generation Mining Limited (CSE:GENM, the “Company”) is pleased to announce that all permits have been received for a sampling program on the Alberta Zinc property (the “Property”) near High Level, Alberta, and that work will commence next week. The program is designed to pinpoint the source of a 4,000-square-kilometre zinc in till anomaly, as manifested by the presence of sphalerite grains, discovered by the Geological Survey of Canada and the Alberta Geological Survey in 2003 (Figure 2). The discovery consisted of numerous sphalerite grains in 30 Kg till samples ranging from values of less than 30 grains in samples external to the anomalous area and grain counts of up to 1047 grains in samples within the anomalous area. Other studies have indicated the likely ice direction of the most recent glacial movement, and the program is designed to systematically sample shallow till samples moving “up ice” until the anomaly ends, thus indicating proximity to the source of sub-cropping zinc mineralization. The Property is underlain by sedimentary sequences of the Western Canada Sedimentary basin (Figure 1). Beneath relatively shallow till cover, Cretaceous aged (80 million years) shales and sandstones are underlain by Devonian aged (370 million years) limestones and dolomites. The Devonian sequence is believed to be stratigraphically equivalent to the Pine Point district (historical production from 1964 to 1987 of 64 million tonnes with an average grade of 7.0% Zn and 3.1% Pb). Of particular importance is the existence of an oil well drilled by Chevron on the Property in 1993 which intersected 10 metres grading 3.7% zinc in Devonian dolomite at a depth of 1250 metres. Mineralization in the Chevron drill hole is believed to be similar to mineralization at Pine Point some 400 km to the northeast and may be an example of Mississippi Valley Type (“MVT”) mineralization. Both Pine Point and the Chevron drill hole are proximal to the Great Slave Lake Shear Zone (“GSLSZ”). There is evidence at Pine Point for two regional periods of increased geothermal activity with one occurring in the Devonian and the other in the Cretaceous. The Zn mineralization in the Chevron drill hole suggests that the GSLSZ has been active in the past and may have provided a locus for mineralizing fluids to move to the surface ...
