Winston Gold Mining has started a Phase-1 drilling campaign on its fully owned gold project near Helena, Montana, US.

This campaign will comprise 15-to-20 holes (4,800ft) using two drill rigs that will target potential high-grade mineralisation in the historic past-producing Custer Vein, as well as along the Edna Vein Trend.

The Winston Gold Project is key to a historic precious and base metal mining district where most of the ore was mined from structurally controlled high-angle fissure veins and lode/replacement zones.

The first hole of the Phase 1 drill programme is currently underway and it is intended to test the sulphide zone of Custer Vein below the 400ft level.

A total of 2,300ft of core will be pulled from the drills to test the Custer Vein.

The Edna Vein Trend features a newly discovered zone where drilling in late-2014 intersected at least two south dipping low-angle veins.

Winston Gold previously confirmed a mineralised zone that was originally identified in historic core hole C171C.

Winston's hole, W1409, yielded 0.44 ounces per tonne (opt) over 1.8ft, and historic core hole C171C assayed 0.38opt over a 9ft composite sample.

Eight Winston core holes also encountered major gold intercepts with values up to 3.14opt in an area that was later called the Edna Trend.

The firm stated that some notable intersections from that previous drill programme include hole W1404 intersected 2.3ft averaging 3.14opt (109.5g/t) of gold; hole W1408 intersected 4ft averaging 0.336opt (11.7g/t) of gold; and hole W1410 intersected 7ft, averaging 0.193opt (6.7g/t) of gold.

"Initial results from drilling will tell me where the best place is to begin drifting and where the decline needs to end up."

Under the present campaign, the first four holes into the Edna Trend will offer data for planning an effective route that the future Hyantha decline will take from the end of the historic Upper Hyantha entrance.

Winston intends to widen the entrance to 10ft x 10 ft to enable access for modern mining equipment. Following this, a new decline will be developed in waste rock to access the Edna Trend Vein system.

Winston Gold director of operations Harold (Mike) Gunsinger said: "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."

The remaining holes will be designed to extend the Edna vein system along the strike.

A total of 2,500ft of drilling has been budgeted for this target.
