IRVING, TX — (Marketwired) — 07/31/14 — (OTCQB: DYNR) DynaResource, Inc. ("DynaUSA", and "the Company") is pleased to announce that Mineras de DynaResource S.A. de C.V. ("MinerasDyna"), the 100% owned subsidiary of DynaUSA and the exclusive operator of the San Jose de Gracia Property in northern Sinaloa, México ("SJG"), is reporting the delivery for sale of approximately 200 Oz. gold contained in gravity concentrates (exact weights in gold and silver oz. to be determined at final settlement).
The production of the estimated 200 Oz. gold was accomplished from mill runs completed over a 10 day period ending July 25, from approximately 1,050 tons of mineralized feed material which was processed through the gravity circuit of the Pilot Mill Facility at SJG. MinerasDyna further reports that approximately 1,025 tons of gravity tailings, remaining after the gravity concentration, will be re-processed through the gravity circuit for metallurgical purposes; and will be processed further through the flotation circuit of the SJG Pilot Mill Facility. MinerasDyna estimates the refurbished flotation circuit to come on line in August. MinerasDyna further reports that the total amount of mineralized material remaining in tailings from the Mill campaigns (May-approximately 2,500 tons processed) and the 10 day July campaign through July 25 (approximately 1,050 tons processed); and together, the combined gravity tailings, are approximately 3,000 Tons. Internal assays report: (a) an average feed grade for the mill runs of approximately 12.0 g/t Au; and, (b) an average grade for the mineralized material to be re-processed (gravity tailings) of approximately 6 g/t.
MinerasDyna estimates approximately 50% of the recoverable gold contained in the feed material mined from the San Pablo Mine to be recovered in the gravity concentrate (considering the results reported in the mill balances from May and July, and based on the review of historical data compiled from the 2003-2006 Period; See "DynaUSA-DynaMéxico below"). MinerasDyna further reports the continuation of contract mining at the San Pablo Mine, where the average gold grade of mined material is reported at 12.5 g/t; including grades up to 300 g/t.
