Mining News: Northern Neighbors: Dolly Varden drills northern silver targets

Dolly Varden Silver Corp. Dec. 23 reported results from a 2,037-meter drill program at its Dolly Varden silver property in northwestern British Columbia. The known Dolly Varden deposits exhibit both volcanogenic massive sulfide (Eskay-like) and epithermal (Brucejack-like) mineralization styles which were the focus of the company’s maiden NI 43-101 mineral resource estimate completed in August. Though this resource remains open to expansion, the goal of the 2015 drill program was to explore targets identified by surface mapping and sampling as having similar high-grade potential in the northern half of the property, where lithologies, alteration and geochemical signatures extend on surface from the property’s historic mines, located on the southern portion of the property. Six holes of this year's 10-hole program targeted Ace-Galena, where the drilling confirmed the presence of VMS mineralization and intersected a new epithermal quartz vein and breccia with high-grade silver. Historical trench and recent surface samples at the McKay showing on Ace-Galena returned assays of up to 3,360 grams per metric ton silver over 1.3 meters. The Ace-Galena trend is projected to extend over a distance of five kilometers (three miles) to the Sault showing, also in the northern half of the Dolly Varden property. The 2015 drill holes at Ace-Galena were targeted to examine this VMS horizon down-dip and along trend of the projected system. Dolly Varden reports that the 2015 Ace-Galena drill holes intercepted highly anomalous silver, lead and zinc mineralization in VMS horizons. Highlights from this drilling include five meters of 51.2 g/t silver from a depth of 89 meters and 22.5 meters of 42 g/t silver from a depth of 110 meters in hole DV15013; and 11 meters of 27 g/t silver from a depth of 90 meters in hole DV15014. Hole DV15019 cut 3.15 meters of 591 g/t silver, but this intercept is considered to be at a shallow angle to mineralization, skewing the results. “We are very encouraged by the results from this new exploration confirming the sub-surface extent of VMS-style mineralization at Ace-Galena,” said Rosie Moore, director and interim CEO, Dolly Varden. “As a bonus, one of the Ace-Galena holes encountered a new, epithermal quartz vein and breccia hosting visible native silver, and returning high-grade silver assays. Both of these mineralization systems warrant further exploration.” In addition to the holes drilled at Ace-Galena, a fan of three holes were drilled in the Kitsol area to follow up on a significant 2014 drill intercept that averaged 712 g/t silver over a true thickness of 22.6 meters. The new holes were sited 60 meters northeast of hole DV14010 and were targeted to test the Kitsol vein down-dip form historic trench results, which graded 626 g/t silver over 4.11 meters. The best intercept from the 2015 drilling at Kitsol was one meter of 117.8 g/t silver from a depth of 148 meters in hole DV15021. Dolly Varden said the new drilling, along with the integration of a structural study completed late in 2015 will assist in the future exploration at Kitsol.
