Fall drilling expands Shumagin

Redstar Gold Corp. Dec. 11 reported that all 13 holes drilled during the 2017 fall exploration program at its Unga gold project on the Alaska Peninsula cut gold and silver.

Most of this drilling, 11 holes, tested the Shumagin Gold zone, expanding this epithermal gold structure to 1,750 meters.

The Shumagin Gold zone has four main areas of mineralization on the basis of location and geology - SW Extension, Main Breccia, Bunker Hill and East Zone.

The fall drill program tested a 750-meter area surrounding Bunker Hill and along strike northeast through East Zone.

Continuity of mineralization occurs between the Main Breccia and Bunker Hill was indicated by drill hole.

"Shumagin is a structurally complex high-grade epithermal system, as highlighted by high-grade zones, or shoots to depth, and indicates continuity at shallow depths ranging from 240 meters to 330 meters below surface," said Redstar President and CEO Peter Ball. "The strong continuity of mineralization identified, and our updated geological model developed, will assist in vectoring future drilling for higher grade mineralization and widths at depth, as seen in previous drilling on the Main Breccia."

Redstar also drilled two holes at Rising Sun, a prospect about 300 meters east of the historic Apollo Mine. These holes were designed to test breccias and stockwork at shallow depths below surface exposures to constrain the dip and textures of the vein breccias and stockwork system. Low grade gold and silver were encountered in both holes. Redstar said additional work is required to vector in to the higher grade zones, as seen at the historic Apollo-Sitka mine.
