Mineral Mountain Resources Ltd. ("Mineral Mountain" or the "Company") is pleased to report final assays from the 2012 Phase I drilling program at its Holy Terror Project (HTP) located 55 kilometres southeast of the formerly producing Homestake Mine in South Dakota, USA. Eight drillholes are included in this release totalling 2,200 metres and were drilled at both the Bismarck Mine area and also the Bullion, Keystone and Holy Terror Mine horizons. The first six drillholes from the Phase I Program were detailed in a Company news release dated November 28, 2012. Maps and sections to accompany this release are posted on the Company's website: www.mineralmtn.com. Detailed drillhole composites are presented in Table 1.
Phase I Bismarck Mine Drilling
Phase I Bismarck Mine drilling was conducted from two drill setups and designed to confirm and expand the gold mineralization defined by previous operators. Highlights from the main Bismarck gold zone include drillhole HT-12-007 which intersected 14.05 g/t Au over 5.0 metres within larger envelope of 4.71 g/t Au over 18.0 metres and HT-12-008 which intersected 2.04 g/t Au over 10.0 metres including 4.80 g/t Au over 2.0 metres. A second zone was intersected in the hanging wall stratigraphy by HT-12-007 occurring approx. 70 metres northeast of the Main Bismarck Zone yielding 1.51 g/t Au over 26.0 metres including 6.46 g/t Au over 4.0 metres. This latter mineralization was confirmed by drillhole HT-12-008 with 0.99 g/t Au having been intersected over 5.0 metres. Holes HT-12-009 through HT-12-011 were collared on a second setup approx. 70 metres southeast of Setup 1 and intersected sporadic gold values including 4.03 g/t Au over 3.12 metres. Given that this drilling intersected completely different rock types than the previous holes in the immediate Bismarck Mine area (Setup 1) and further justified by new geological modeling, it is concluded that faulting has occurred which has offset the Bismarck Mine stratigraphy in this area. Strike and depth extension drilling of the immediate Main Bismarck Zone will be a major focus for the 2013 Phase II drilling.
Phase I Bullion, Keystone and Holy Terror Mines Drilling
Two drillholes were collared from a single setup at the Bullion Mine adit and were designed to intersect the Holy Terror Mine below the lowest development on the 1200' level. Since production ceased indefinitely in 1903, this is the first time any operator has drill tested the Holy Terror Mine horizon. Drillhole HT-12-013W successfully confirmed the Holy Terror Shear Zone at depth intersecting 4.18 g/t Au over 3.0 metres (including 5.31 g/t over 2.0 metres) within a larger envelope grading 1.79 g/t Au over 13.0 metres. This very aggressive first hole is located approx. 260 metres down dip of the deepest mine workings and approx. 590 metres vertically below surface. Including all historical drill campaigns, this is the deepest drillhole ever drilled on the project. Based on historical records, mined ore at the Holy Terror Mine was dominated by free gold hosted in quartz veins within a wider zone of sheared rocks with very low quantities of sulphide. The mineralization intersected in HT-12-013W was devoid of quartz veining and dominated by graphitic schistose rocks with sporadic sulphide mineralization. Due to limited structural information being available for the plunge geometry of the Holy Terror mineralization, it is unclear whether HT-12-013W pierced the core of the system or if it lies outside the plunge corridor.
