Calvista Gold Corp. Intersects 17.15 g/t Gold Over 4.00 m and 11.34 g/t Gold Over 7.00 m at Its Buenavista Prospect
25.07.2012 | Marketwire
TORONTO, 07/25/12 - Calvista Gold Corporation (TSX: CVZ) (OTCQX: CAGOF) ("Calvista" or the "Company") is pleased to announce that recent drilling at its Buenavista prospect, along strike from AUX Canada Acquisition Inc. Aserradero mineralized zones, has returned high grade gold intersections.Highlights from the recent Phase II drilling program at the Buenavista prospect include:
DDH-44 - 3.00 metres @ 7.80 g/t gold, and 5.00 metres @ 3.87 g/t gold
DDH-45 - 5.15 metres @ 2.56 g/t gold
DDH-47 - 4.00 metres @ 5.34 g/t gold, and 7.00 metres @ 11.34 g/t gold
DDH-48- 4.00 metres @ 17.15 g/t gold, and 4.00 metres @ 4.20 g/t gold
The Company's Chief Executive Officer, Mr. Mark Haywood, stated that "the number of high grade gold intersections returned from the 2,500 metre drilling program at the Buenavista prospect are very encouraging. Based upon the Phase II drilling program results, the Company expects to publish an updated NI 43-101 mineral resource by end of this quarter."
The Phase II program at the Buenavista prospect targeted mineralized zones identified in our Phase I drilling program, plus along strike extensions from the Aserradero mineralized zones (being developed by AUX Canada Acquisition Inc.).
The number of high grade intersections observed by Calvista suggests a porphyritic environment with disseminated gold-silver mineralization and associated copper.
Selected drill hole results from our Buenavista prospect, using a cut-off grade of 1.0 g/t of gold, are provided in Figure 1. Selected results from the entire Phase II drill program are also provided in the Appendices.
A 10,000 metre phase III diamond drilling program is currently being prepared, and is expected to commence in the last quarter of this year.
