The geological setting of the Anoroc zone is similar to that of the Pine Cove Deposit. The occurrence is hosted by sheared mafic volcanic rocks, tuffs and mafic intrusive rocks of the Point Rousse Complex cover sequence immediately north of the Scrape Thrust.
Corona Corporation discovered the Anoroc (Corona spelled backwards) prospect in 1990. The prospect has been trenched and in 1990 was tested by 5 diamond-drill holes (Figure AR1), The Anoroc Extension located just north of the Anoroc was discovered around the same time, but very little information is available on that showing.
Mineralization comprises disseminated pyrite and pyritiferous quartz and quartz breccia veins associated with chloritization, iron-carbonate and minor silicification. As with Pine Cove the mineralization appears to be controlled by both the geometry of the folding and the host lithologies.
Channel sample assay results from trenches on the Anoroc zone included 3.2 g/t Au over 3 m and 7.8 g/t Au over 2 m and this included a section which assayed 14.2 g/t Au over 1m. Samples from diamond drilling (An-90-1) assayed up to 9.9 g/t Au over 2 m, which included 18.9 g/t Au over 1m (Table AR1; Figure AR2). Grab samples collected from the Anoroc Extension assayed 7.5 and 6.0 g/t Au.
