Mac porphyry molybdenum prospect, north-central British Columbia

"The Mac porphyry molybdenum prospect is located 100 km east of Smithers in central British Columbia. The identification of anomalous levels of molybdenum, copper, and silver in three adjacent lakes, sampled during a regional lake sediment survey, lead to the discovery of molybdenite mineralization in float. Subsequent magnetic and soil geochemistry surveys, together with prospecting and mapping, located the source of the float. Mineralization is hosted by a leucocratic granite stock of the Upper Jurassic to Lower Cretaceous Francois Lake Intrusions which has intruded Carboniferous and Permian Cache Creek Group volcanic and sedimentary rocks. The stock measures 500 m by 300m at surface and is mineralized throughout. Sulphide mineralogy is simple and consists of molybdenite with minor pyrite and local chalcopyrite. Molybdenite occurs within fractures and as selvages along quartz stockwork veins and is best developed near the margins of the stock.Known mineralization is coincident with distinct soil geochemistry and magnetic anomalies. Two additional areas of the property display similar features and these remain to be tested.IntroductionThe Mac property is situated in the Babine Lake area of central British Columbia on NTS map sheet 93K/13E, approximately 100 km east of the town of Smithers (Fig. 1). The property lies on the western margin of the Hogem Range at the northern tip of the Nechako Plateau. The centre of the claim block lies at 54°51 ' 30""N and 125 °34 '30""W.Topographically, the claims are characterized by gently rolling hills ranging in elevation from 900 m to 1500 m. Slopes are forested with tall conifers and underbrush is minimal. Flat-lying areas are swampy with tall grasses and scrub brush.Presently, the property is only accessible by helicopter from bases located in Smithers and Fort St. James. Recent road construction by the British Columbia Forest Service has brought road access from Burns Lake to within 5 km due south of the property. It is expected that in the near future, roads will be advanced into the claim area to facilitate logging of mature timber."
