Historic Borys Lake Zinc-Lead Volcanogenic Massive Sulphide (VMS) Deposit
- On October 16th – 21st, field crews investigated a number of historic trenches on both the Borys Lake trend and the parallel Cominco trend
- Assay results not only confirm mineralization, but in several instances significantly exceed known historic results.
The Borys Lake trend follows a southwest-northeast orientation and occurs along a lithological contact between a Metabasite-Amphibolite to the south and Pelitic-Psammitic gneiss to the north.
The Borys Lake trend includes five historic drill confirmed mineralized zones (Can, Will A, Will B, Main and Mac) and numerous historic outcrop trenches over ~4.5km of strike.
During October 16th – 21st, field crews investigated a number of historic trenches on both the Borys Lake trend and the parallel Cominco trend located approximately 3km to the south. A total of 7 historic trenches were located and representatively sampled.
Assay results not only confirm mineralization, but in several instances significantly exceed known historic results. Assay results from trenches along the Borys Lake zone confirm that mineralization of zinc, lead and silver is strongly anomalous and generally occurs together.
Trench 4, located at the SW end of the Borys Lake Main Zone returned the highest zinc values with up to 21.3% Zn while Trench 8, located a further 1km to the SW in the Will A Zone yielded the highest silver values with up to 184 g/t Ag.
VMS: Important Deposit Type in Canada
- In Canada, VMS mining responsible for 49% of Zn, 20% of Pb, 27% Cu and 40% of Ag
- Flin Flon district near SK-MB border has been a historically important district for VMS ore production
- Watts Lake project located ~150km to west of Flin Flon in same geologic domain
VMS: Volcanogenic Massive Sulphide Deposits
- VMS deposits form on sea-floor in submarine volcanic environments whereby hot water hydrothermal vent systems precipitate massive sulphide metal mineralization
- VMS Deposits are often found in clusters and can be major sources of zinc, copper and lead & often include silver and gold as by-products
- 350 VMS deposits in Canada and 850 worldwide
