The Chrysocolla target covers an area of at least 300 by 300 metres and was the focus of exploration during the 1997 and 2004 drill campaigns where 14 drill holes were completed. The drill holes targeted porphyry related copper and gold mineralization and overprinting quartz + sulphide vein hosted gold mineralization. Drilling in this area in 1997 returned numerous gold and copper intersections such as 33 metres of 0.76 g/t Au with 0.27% Cu in drill hole DDH-97-17. Furthermore, historic drilling 150 metres north of the main trench retuned an impressive gold intersection highlighted by 10 metres of 12.35 g/t Au in DDH-97-07, reportedly characterized by fracture controlled pyrite and chalcopyrite mineralization.
Western Magnetite Zone
The poorly exposed Western Magnetite Zone is underlain by Nicola volcanic rocks coincident with a ground magnetic anomaly covering an area of 600 by 400 metres. The centre of the magnetic anomaly has been tested by multiple shallow percussion holes in the early 1970s and by two diamond drill holes in 1975. The diamond drill holes were shallow but reportedly intersected intervals characterized by magnetite breccias with copper sulphide mineralization. Three follow-up diamond drill holes were completed in 1997 collared 350 to 400 metres east of the magnetic anomaly and intersected copper and gold mineralization hosted in strong albite + magnetite + biotite altered volcanic rocks. Here, disseminated and vein controlled sulphides are pyrite, chalcopyrite and lesser bornite. One such hole returned an interval of 31.5 metres of 0.16 g/t Au with 0.37% Cu (DDH-97-09).
Central Monzonite Zone
The Central Monzonite Zone spans the core of the Durand Stock with copper mineralization covering a strike length of greater than 1.5 kilometers. Ubiquitous copper mineralization characterized by disseminated and clotted chalcopyrite is associated with varying degrees of carbonate + epidote alteration. One diamond drill hole in 1997 tested the Central Monzonite zone on the western side following up on a geochemical anomaly (located 900 metres west of the historic trench where Tower's grab sample 1709453 yielded 1.32% Cu with 0.27 g/t Au and 3.9 g/t Ag). This hole (DDH-97-08) intersected copper mineralization in the bottom of the hole comprising clotted chalcopyrite. An interval of 20 metres of 0.14 g/t Au with 0.35% Cu was returned. This area is open in all directions and at depth and warrants deep diamond drilling.
