Figure 5: Semi-massive, primary uranium mineralization at 348.5 m, maximum peak of 47,200 cps as shown


Figure 6: Semi-massive, primary uranium mineralization hosted in competent garnetiferous orthogneiss at 356.9 m, maximum peak of >61,000 cps


Figure 7: Secondary mineralization along microfractures and foliation at 367.3 m, maximum peak of 28,500 cps



Semi-massive replacement by uranium mineralization is tied to brittle-ductile reactivation of steeply dipping, discrete shear zones bracketed by silicified orthogneiss. Localized semi-massive mineralization includesprimary uraninite and secondary uranium minerals. Textural characteristics of mineralization and associated alteration indicate a well-developed hydrothermal system with fluid pathways provided by the structural disruption. In particular, the role of bounding silicification, mineralization style, and stacked brittle-ductile faults are analogous to features found at Arrow (Figures 4 to 7).Figure 1:
