Drill hole ML-134. (a) General overview of the mineralized interval @205.3-249.2 m. (b) Microfractures filled with secondary graphite or dark chlorite @210.4 m, <830 cps. (c) Fracture and quartz-feldspar segregation-related mineralization @209.8 m, <15.340 cps. (d) Limonite oxidation front-related mineralization @217-217.3 m, <21.630 cps. The sketch shows the geometric relationship between the front, the foliation, and the fold. (e) Oxidation front-related mineralization @221.4 to 221.8 m, <11.700 cps. The sketch shows the geometric relationship between the front and the foliation. (f) Upper contact of principal mineralization @223.5 m. (g) Lower faulted contact of principal mineralization @227.8 m. (h) Clay fault @227.4 m, 10.500 cps.
