VANCOUVER, Feb. 27, 2012 - Northern Vertex Mining Corp. (TSX.V:NEE)(OTCQX: NHVCF) ("Northern Vertex") is pleased to announce results from the first 18 holes of its 20,000 foot (6500 meter) in-fill drill and resource expansion program on the Moss Gold-Silver Project situated in the historic Oatman Mining district in Mohave County, Northwestern Arizona.
States Northern Vertex Chief Geologist, Dr. Bob Thompson. "We are pleased to report all five of the Phase II infill holes, AR-124, 125, 127, 128 and 133, designed to convert resources from the inferred to the indicated category, were successful, with each hole intersecting at least 24 metre widths of mineralized material.
The significant intersections returned from Phase II drilling are consistent with results from our Phase 1 drill program. Importantly, they demonstrate the consistent internal distribution of gold weve come to expect from the Moss gold-silver system. Holes AR-121, 122 and 123 returned a series of promising intercepts, despite being stopped in mineralization grading 1 gpt gold equivalent. These holes were collared approximately 160 meters south from the outcropping Moss stockwork system, where intersections suggest a broader zone of mineralization at depth."
Hole AR-136 intersected 1.52 m averaging 19.39 gpt gold equivalent. "Were encouraged because 19.39 gpt gold equivalent is an order of magnitude higher than typical Moss grades and implies there are volumes of high-grade material yet to be drilled," remarks Thompson. The hole was drilled near historic workings located at the southern boundary of the patented claims, about 400 meters south of the Moss stockwork system.
The second part of the Phase II program, designed to test the western extension, is now underway using a specialized core-drilling rig. "We are optimistic heading into this next phase of drilling, based on results from the one RC (reverse circulation) drill hole (AR-132) that we were able to drill into a considerably steeper part of Mosss terrain, which returned mineralization from nearly top to bottom, over a total of 84 metres," adds Thompson
