Capsule Geology

The Edon showing lies on the western flank of Ehahcezetle mountain above Eddontenajon Lake, approximately 5 kilometres southeast of the village of Iskut. The showing occurs in the dissected highlands of the Tanzilla Plateau.

Refer to the MFJ prospect (104H 001), located 3.5 kilometres to the east-southeast, for work history, and local and regional geology.

The Edon showing comprises a large (1 by 1.5 kilometre) pyritic "Stain Zone" containing several mineralized occurrences with visible chalcopyrite and molybdenite. The quartz monzonite stock, which intrudes unnamed Upper Triassic to Lower Jurassic fragmental feldspar porphyritic andesite, hosts the occurrences and has undergone intense quartz-sericite alteration and the introduction of tourmaline. The stock is possibly related to the Early Jurassic Rose and Edon Plutons. The Stain zone lies within a well developed propylitic alteration envelope marked by abundant chlorite, epidote and pyrite.

A single drillhole tested the mineralization at depth, and the best assay was 0.05 per cent copper, 0.2 gram per tonne gold and 0.01 per cent molybdenum (Assessment Report 8481).

In 2010, three grabs of propylitically altered andesite breccias yielded anomalous copper values of 5226, 7267 and >10,000 parts per million but only a single anomalous gold value of 14 parts per billion and no anomalous molybdenum values (Assessment Report 31817).

In late 2009, Brett Resources Inc. staked the North Rok claim group and then in mid-2010 carried out a reconnaissance-style program to test for possible extensions of the Rok-Coyote copper-gold system (104H 001, 12, 24). The program included silt sampling of creek drainages, prospecting and rock sampling of colour anomalies and known copper showings and occurrences and systematic rock chip sampling along elevation contour lines over the Edon stock and across the Plateau occurrence (104H 034).
