General comments

Subject category Comment text
Deposit MAIN ORE BODY (BEATSON) IS A LENS OF DISSEMINATED ORE ALONG THE FOOTWALL OF THE BEATSON FAULT. THE ORE BODY IS BOUNDED ON THE EAST ONLY BY THE LIMIT OF ITS ECONOMIC VIABILITY, AS THE DISSEMINATED LODE GRADES INTO COUNTRY ROCK AND ON THE WEST BY THE FAULT ITSELF. POCKETS OF PARTICULARLY RICH ORE WERE LOCATED PROXIMAL TO FAULT. THE CHINEGA AND BLACKBIRD ORE BODIES OCCUR TO THE NORTH ALONG THE SAME TREND AND ARE OF SIMILAR MORPHOLOGY AND MINERALOGY, THOUGH MUCH SMALLER AND PERHAPS SOMEWHAT RICHER (TOWARDS MASSIVE). INTERPRETED TO BE CYPRUS TYPE MASSIVE SULFIDE (D. SINGER, PERSONAL COMMUNICATION, 1984)
