Capsule Geology

The H Vein, which is located 900 metres north-northeast of the Big Missouri deposit, lies within south-southeast striking, moderately dipping andesite, agglomerate and lapilli tuff, with interbedded cherty tuff of the Lower Jurassic Unuk River Formation. (See Big Missouri - 104B 046 for enhanced geology).

The H Vein, which trends north for 75 metres, is flat lying and between 0.15 to 1.0 metres thick. This quartz vein is well mineral- ized with pyrite, galena, sphalerite, tetrahedrite, and native silver. A composite sample of twelve grab samples assayed at 6.2 grams per tonne gold and 2571 grams per tonne silver (Cochrane, 1974).

The nearby I Vein, which strikes east and dips 45 degrees south, is 0.3 to 1.0 metre wide and is mineralized with pyrite, sphalerite, native silver and minor galena.

In 2010, Ascot Resources' drillhole P10-068, drilled in the vicinity of the H Vein, is included by Ascot in the Unicorn zone (104B 044). This hole was drilled east toward the bulk of the 2009 and 2010 Ascot drilling. Hole P10-068 contained 211.4 metres grading 0.44 grams per tonne gold. The H or I veins are not mentioned by Ascot.

See Unicorn (104B 044) for specific related work history and Big Missouri (104B 046) and Premier (104B 054) for related details of the Dilworth and Premier properties that were held as a single entity in the 2000s by Boliden Ltd and Ascot Resources.
