Feldspar separates consisted of alkali feldspar, either albitic plagioclase or potassium feldspar, or mixtures of both.
Some of the crystals contain inclusions of very fine-grained tourmaline or euhedral, green-blue apatite, and some are veined by free-grained, equigranular apatite that is indicative of albitic replacement (Breaks, 1989).
Surface work has indicated shearing, strong sericitic to albitic alteration and quartz veining with grab samples to 1 gpt gold.
