Patagonia Gold Provides Updated Resource Estimate For Cap-Oeste Gold-Silver Deposit, Argentina
TORONTO, Sept. 10, 2012 /CNW/ - Patagonia Gold Plc (TSX: PAT), (AIM: PGD) ("Patagonia Gold" or "the Company") today announced an updated resource estimate for the Cap-Oeste Gold-Silver project in Santa Cruz province, Argentina.
Highlights:
- 24% increase in the Indicated Resource: Total gold equivalent (AuEq) ounces within the indicated category, is now increased to 1,197,000 reported above 0.30 g/t cut-off, an increase of 230,000 AuEq ounces with respect to the previously reported November 2011 resource.
- 30% increase in grade: Indicated resource reported above 0.30g/t cut-off now grades 4.78g/t AuEq with respect to the previously reported November 2011 grade of 3.68g/t AuEq.
- The resource remains open along strike and down dip in both directions. Resource extension-exploration drilling is planned to restart in October 2012 on the Cap-Oeste structure targeting primarily the highly prospective COSE-Cap-Oeste corridor.
Commenting on this report, CEO of Patagonia Gold, Bill Humphries, said:
"Patagonia Gold remains focused on the discovery and development of high grade, low cost resources within our exciting portfolio of properties in the highly prospective Deseado Massif, Santa Cruz. This resource update has successfully increased both the grade and the ounces within the Indicated category on our high grade Cap-Oeste project. Patagonia Gold will now commence pre-feasibility studies in order to advance the project towards production, potentially for 2015."

Patagonia Gold contracted Chlumsky, Armbrust & Meyer LLC (CAM) of Lakewood, Colorado, to independently audit and classify an updated mineral resource estimate for the Cap-Oeste gold and silver deposit, Santa Cruz Province, Argentina, and to prepare a technical report in accordance with Canadian National Instrument 43-101 (NI 43-101).
The Cap-Oeste deposit has been split into 3 distinct material types for modelling process, 1) oxide material, containing material which is highly oxidised and potentially amenable to cyanide in leach (CIL) or Merrill Crowe (MC) processing methods 2) sulphidic material, material which is predominantly non-oxidised and contains a high percentage of unweathered/oxidised sulphide minerals which will be amenable to either CIL, MC or flotation processing methods and 3) veinlet sulphide material, again sulphidic in nature although represents mineralisation not associated with the main fault breccia system and is associated with the Esperanza fault. Each material type attributed to the respective Indicated and Inferred resource categories is shown below.

The resource upgrade, generated from the Phase 3 drilling campaign consisting of 57 HQ diamond core drill-holes for a total of 20,210 metres, commenced in August 2011 and was completed on the 3rd February 2012. Drilling was targeted principally at the lower part of the Cap-Oeste deposit containing high grade intersections within and around the inferred tonnage of the November 2011 resource upgrade. The drilling successfully increased the grade, the contained ounces and the confidence level of the deposit.
The full Resource and report will be posted on the website, www.patagoniagold.com, as soon as practicable.
Global Resource:
Patagonia Gold has so far delineated indicated resources totalling 1,478,000 ounces AuEq and inferred resources totalling 398,000 ounces AuEq on the Cap-Oeste, COSE, Manchuria and Lomada deposits in the aggregate. All resources were estimated in accordance with NI 43-101.
El Tranquilo Property:
The El Tranquilo property block, covering approximately 80,000 hectares, contains Patagonia Gold's flagship project, Cap-Oeste deposit, together with the COSE bonanza gold and silver deposit and numerous other prospects including Monte Leon.
Cap-Oeste Deposit:
The Cap-Oeste mineralization has now been intersected over a distance in excess of 1200m along the Bonanza fault structure, the majority of which is concentrated within a strike length of 650m by 350m in depth and in excess of 12m in average true width. The thickening of the mineralisation is due to areas of dilation where 2 or more major structures intersect. These zones of structural complexity exhibit the most potential for future resource expansion and are now the focus of future exploration. The Cap-Oeste deposit remains open along strike in both directions and down dip.
Phase 4 drilling continued through February to May 2012 and to date 43 HQ diamond core drill-holes for a total of 12,010m, have been completed towards the next planned resource update, expected in the early 2013. Drilling is scheduled to recommence in Q4 2012 with the area of main interest being the relatively unexplored corridor between Cap-Oeste and the bonanza grade COSE deposit situated 1.8km to the south east of the main Cap-Oeste mineralised system. Recent drilling to the north west of the COSE deposit (announced in an RNS dated July 5th, 2012 titled "Drilling Update for Cap Oeste South East Deposit") has intersected mineralisation of similar texture and nature to COSE up to 200m from the main mineralised COSE body.
Patagonia Gold has now commenced the search for a consultancy group and feasibility study project manager to advance Cap-Oeste to the next stage, which will consist of a full pre-feasibility study and extensive metallurgical testwork programmes. The latter are currently underway in Australia and Canada. As part of this process, the most appropriate mining and process methods will be investigated and designed and together with a comprehensive estimation of the projected capital requirements and operating cost analysis will be undertaken. The study is scheduled to start in Q1 2013 subject to the availability of the selected consulting groups. Both international and local groups will be used throughout the study. Progress reports will be given as the study is developed and before a decision to move into full feasibility is taken.
