The Quill zone is underlain by Upper Triassic Stuhini Group volcanic, volcaniclastic and sedimentary rocks intruded by dioritic phase of the Stikine (or McQuillan) Plutonic Suite.
The Quill zone contains abundant float with high grade gold and copper mineralization in a quartz vein system (Assessment Report 25819). Work in the late 1990s found disseminated and thin vein pyrite but results from sampling are low. The veins around the Quill showing typically range from a few millimetres to 20 centimetres wide and are largely hosted by andesitic rocks and less commonly diorite. These showings have returned significant gold and silver values with anomalous zinc and arsenic, however, the veins are narrow and discontinuous. The highest values seem to have been obtained from the abundant mineralized float in the area.
Work History
In 1995 Allan St James prospected the Quill claim and collected 4 float samples that contained up to 64.05 grams per tonne gold, 45.8 grams per tonne silver and 6.33 per cent copper (Assessment Report 24482). The area where the float as most common was renamed the “Q-zone. The zone is located about 600 metres south-southwest of the Windy Tarn (MINFILE 104B 625)showing and about 450 metres east of the Fred (MINFILE 104B 231).
In 1998, Allan St James set out a grid over an area of about 500 by 1000 metres covering part of the Quill claim, and carried out mag and VLF-EM surveys, and geological mapping and prospecting on the grid area (Assessment Report 25819).
Seven short holes totalling 394.85 metres were drilled by Petra Resources in 1999 over the Quill (Q) zone. Four were completed at their planned depths between 60.05 and 85.34 metres, and two were abandoned at 15.38 meters. These holes explored an approximately 100 metres length of the area containing the known quartz veins above the zone. The steep shears with quartz-calcite veins continue through the zone, but those encountered in drilling were low in gold, fairly thin, and individually lacking continuity.
