Comstock Metals Ltd. is pleased to announce the discovery of porphyry-style gold mineralization from its core drilling programme at the Corona Project in the Uruachic-Ocampo District of western Chihuahua, Mexico. The Uruachic-Ocampo District is host to several multi million-ounce gold/silver deposits, including Fresnillo PLC’s Orisyvo Deposit with a reported resource of 9.2 Million ounces of gold. At Corona, porphyry-style gold mineralization has been identified, and remains open to the north, east and at depth. The most recent eight drill holes completed by Comstock intersected favourable geology and strong alteration east and southeast of the Northeast Zone, stepping-out up to 350 m from holes drilled in 2002-2003. A new zone of porphyry-style gold mineralization was intersected beneath the previously reported vuggy silica lithocap (see CSL news release dated April 2, 2012 for results of holes CO-12-60 to 62).

Serengeti Resources Inc. is pleased to announce results from the first three holes of a recently completed 19 hole reverse circulation (RC) drill program at the Victoria project. Hole V-01 encountered a near surface oxide gold-silver zone grading 1.68 g/t Au and 4.8 g/t Ag over 7.5 metres, while both holes V-01 and V-02 encountered widespread polymetallic (gold-silver-zinc) mineralization, indicative of an epithermal sedimentary replacement deposit. Holes V-01 and V-02 were drilled along a northeast-southwest fence. The remaining 17 holes were drilled on step out fences to the north and south to test a 2.0 kilometre long target area. The balance of the results will be released as they become available.

The remainder of the holes reported in this release were drilled into the Main Ixtaca Zone with holes TU-120, 123 and 124 from infill sections spaced at 25 meters from previous 50 meter spaced sections. Holes TU-12-108, 111, 117 and 121 on sections 10750 and 10800 demonstrate continuity of the Main Ixtaca Zone up-dip and along strike to the northeast.
