In 2012, after reviewing digitized historic soil geochemical data for the Ming’s Bight Peninsula, Silvertip Exploration Consultants identified several areas lacking soil geochemical coverage. This included an approximately 0.8 km by 1.25 km-long zone laying immediately east of the Deer Cove Road and north of the Ming’s Bight Highway, referred to as the Ming’s West area (Figure ST1). The area is included in mineral exploration licences 12433M (Tenacity Option) and 20060M (Froude Option).
A reconnaissance soil survey was carried out in 2012 using flagged 100 m-spaced lines (Figure ST9). A total of 364 samples were collected at 25 m intervals. One hundred and twelve samples assayed 25 ppb Au or greater to a maximum of 4.88 g/t Au. Several pieces of mineralized float were collected during the soil sampling and returned assay values up to 9 g/t Au. Additional prospecting led to the discovery of mineralized and altered gabbro exposed near a small brook just east of the Deer Cove Road, called the Bruce Showing (Figure ST9). Grab samples from the altered gabbro assayed 3.4 g/t Au and 7.5 g/t Au.
In 2013, Anaconda completed an airborne magnetic survey covering the Ming’s Bight Peninsula. In the Ming’s West area many of the anomalous soils were found to be coincident with magnetic lows (Figure ST10).
In late 2014, Anaconda completed 633 m of trenching on licence 12433M and 113 m of trenching on adjacent licence 20060M (Figure ST10). The trenching exposed strongly-altered, quartz-veined and pyritized gabbro, which was subsequently called the Argyle zone. Grab samples and channels revealed the presence of high-grade gold mineralization associated with the altered gabbro. Highlights of the trenching included: 3.75 g/t Au over 16 m (including 8.27 g/t Au over 4 m) and 1.49 g/t Au over 3.5 m in trench ATR-14-08; and 1.31 g/t Au over 11 m in trench ATR-14-12 (Figure ST10). An early snowfall prevented additional work from being completed.
Additional trenching was carried out in late 2015 (Figure ST10). 66 m of channel sampling was completed in three trenches. ATR-15-18 was excavated approximately 40 m west of Trench 12. It returned assays of 1.47 g/t Au over 14 m which included 10 m that assayed 1.9 g/t Au.
