Winston Gold Mining Corp. ("Winston Gold" or the "Corporation") is pleased to announce that it has commenced a Phase-1 drilling campaign on its wholly owned Winston gold project near Helena, Montana.
The Phase 1 program will consist of 15-to-20 holes (4,800 ft) using two drill rigs that will target potential high-grade mineralization in the historic past-producing Custer Vein as well as along the Edna Vein Trend.
The Winston Gold Project is central to a historic precious and base metal mining district in which most of the ore was mined from tightly structurally controlled high angle fissure veins and lode/replacement zones. Reports indicate that more than 100,000 ounces of gold was recovered from these underground mines in the late 19th to early 20th century from about 150,000 tons of ore. (Earle, 1964; Schell, 1963).
The Custer Mine was developed for 2,400 ft along the Custer vein which averages about 4 ft wide. It was mined sporadically between 1930 and 1955. The average gold price over its production life was just US$34.47 per ounce. Very little un-oxidized, sulphide rich, ore was mined beneath the water table at 4,180 ft elevation (or the 400 ft level). Dewatering was expensive and not cost effective at that time. The Winston property was historically drill tested for near surface bulk mining potential but the Custer vein was never drilled.
The first hole of the Phase 1 drill program is already turning and it is designed to test the sulphide zone of the Custer Vein below the 400 ft level. A total of 2,300 ft of core will be pulled from the drills to test the Custer Vein.
The Edna Vein Trend represents a newly discovered zone where drilling in late 2014 intersected at least two south dipping low-angle veins. Refer to NI-43-101 report authored by Dr. Richard C. Capps, Ph.D. dated April 27th 2015 on Sedar.com.
Winston Gold Corp previously confirmed a mineralized zone that was originally identified in historic core hole C171C. Winston's hole, W1409, assayed 0.44 ounces per ton (opt) over 1.8 feet and historic core hole C171C assayed 0.38 opt over a 9 foot composite sample. Eight Winston core holes also intersected significant gold intercepts with values up to 3.14 opt in an area that was later dubbed the Edna Trend.
Some notable intersections from that earlier drill program include:
- Hole W1404 intersect 2.3 ft averaging 3.14 opt (109.5 g/t) gold
- Hole W1408 intersected 4 ft averaging 0.336 opt (11.7 g/t) gold
- Hole W1410 intersect 7 ft averaging 0.193 opt (6.7 g/t) gold
In the current program, the first four holes into the Edna Trend will provide data for planning the most effective route the future Hyantha decline will take from the end of the Historic Upper Hyantha adit. Winston plans to widen the adit to 10-by-10 ft to allow access for modern mining equipment. A new decline will then be developed in waste rock to access the Edna Trend Vein system.
"The initial results from the drilling along the Edna trend will tell me where the best place is to begin drifting and where the decline needs to end up," commented Harold (Mike) Gunsinger, Director of Operations for Winston Gold.
The remaining holes will be designed to extend the Edna vein system along strike. A total of 2,500 ft. of drilling have been budgeted for this target.
The technical results contained in this press release have been reviewed and approved by Dr. Criss Capps PhD. P.Geol., and independent consultant to Winston Gold Corp. Dr. Capps is a Qualified Person as defined in National Instrument 43-101.
