Playfair announces that drilling is in progress at its Mount Uniacke Project, part of Playfair’s Golden Circle Project in Nova Scotia. Playfair is fully funded for the drill program totaling 2,950 metres in 41 drillholes to test for high grade gold at modest depths below the shallow historical surface workings together with testing for bulk tonnage gold near historical large open cuts.

Three of the planned six holes on the historic West Lake Mine have been completed to date.

The targeted three-prong drill program is summarized below.

West Lake Mine Area

This initial drilling is designed to directly test the conclusion of E.R. Faribault, as reported by Malcolm (1929), that veins north of the historic Borden Vein “may prove very rich at the crumple.” The program consists of two groups of three 100-metre holes (600 metres total) drilled from the same setups. The strategic objective is to test this specific, high-grade structural target where the veins are predicted to be thickened by the “Crumple” at a relatively shallow depth, providing a rapid and cost-effective validation of a long-standing geological thesis.

Central Crossing

This phase of drilling will consist of 10 locations with 3 shallow drill holes each (30 shallow drill holes for a total of 1,550 metres). It is designed to locate and explore the “Crumple” structure where it is projected to intersect a major north-south vein zone, approximately 850 metres away from the well-mapped West Lake Mine. The objective of this work is to delineate the scale and continuity of this critical gold-bearing structure and understand its potential to host significant mineralization where it interacts with, and potentially thickens, other known gold-bearing veins.

Open Cut Area

This component of the program will test an entirely different deposit model, leveraging historical evidence of open-cut mining of low-grade material (2.8 g/t). This drilling, comprising four 100-metre holes and one 400-metre hole (800 metres total), will test the potential for a high-tonnage, disseminated gold deposit. The rationale is strongly supported by a poorly sampled 1995 drill hole (MU 95-1) which assayed 2.6 g/t Au from unremarkable core that was adjacent to unsampled sections, underscoring the potential for a much larger mineralized system than previously understood.

Playfair’s CEO Don Moore said “Playfair is excited by the opportunities available in Nova Scotia’s New Gold Era. We are looking forward to drill results from the first core drilling at Mount Uniacke in over 30 years.”
