Minefinders Reports First NI 43-101 Compliant Resource for Its La Bolsa Property
Monday September 14, 9:15 am ET
"This NI 43-101 compliant resource is an important step in advancing the La Bolsa property to a construction decision," commented Mark Bailey, President and Chief Executive Officer. "La Bolsa has the potential to be the Company's second low cost mine and, concurrent with the in process pre-feasibility study on the construction of a mine at La Bolsa, we are continuing the ongoing drill program to further expand the resource."
The resource estimate at varying cutoff grades is provided in Table 1 below:
------------------------------------------------------------------------- La Bolsa Measured and Indicated Resources ------------------------------------------------------------------------- Cutoff Tonnes Gold Silver ------------------------------------------------------------------------- gpt Au T x 1000 Grade (gpt) Ounces Grade (gpt) Ounces ------------------------------------------------------------------------- 0.200 17,660 0.658 373,497 8.9 5,040,873 ------------------------------------------------------------------------- 0.250 15,896 0.706 360,722 9.4 4,824,472 ------------------------------------------------------------------------- 0.300 14,034 0.763 344,247 10.1 4,564,973 ------------------------------------------------------------------------- 0.400 10,298 0.913 302,426 11.9 3,942,392 ------------------------------------------------------------------------- 0.500 7,641 1.076 264,294 13.9 3,405,859 ------------------------------------------------------------------------- 1.000 2,547 1.846 151,121 23.7 1,939,460 ------------------------------------------------------------------------- ------------------------------------------------------------------------- La Bolsa Inferred Resources ------------------------------------------------------------------------- Cutoff Tonnes Gold Silver ------------------------------------------------------------------------- gpt Au T x 1000 Grade (gpt) Ounces Grade (gpt) Ounces ------------------------------------------------------------------------- 0.200 4,091 0.427 56,105 4.2 557,892 ------------------------------------------------------------------------- 0.250 2,843 0.519 47,436 5.3 480,029 ------------------------------------------------------------------------- 0.300 2,051 0.614 40,475 6.0 393,490 ------------------------------------------------------------------------- 0.400 1,052 0.861 29,126 8.6 291,883 ------------------------------------------------------------------------- 0.500 456 1.400 20,543 15.3 224,707 ------------------------------------------------------------------------- 1.000 138 3.117 13,848 37.0 164,560 -------------------------------------------------------------------------
The resource estimation is based on the results from 165 drill holes (81 reverse-circulation holes and 84 core holes) completed within the property. The Company is continuing to drill on the property with both a core drill rig and a reverse-circulation drill rig in order to continue to define the overall extent and geometry of the La Bolsa mineralized zone. The resource estimation was prepared by the Company using Gemcom Gems software. The estimation procedures, database and results have been independently reviewed and audited by David Linebarger a "qualified person" with Sacrison Engineering of Elko, Nevada. A NI 43-101 compliant technical report will be filed by the Company within 45 days.
The gold mineralization occurs within a shallowly dipping continuously mineralized oxidized blanket that is subparallel to topography and approximately 1,000 meters (3,300 feet) in length and up to 800 meters (2,600 feet) in width with thicknesses that range from 10 to 50 meters (30 to 165 feet). Recent drilling at La Bolsa continues to extend that zone and this mineralization remains open both down-dip and along strike.
A pre-feasibility study of the economic viability of a mine at the La Bolsa property is in process with results expected to be reported by the end of this year. This updated resource and results from the current La Bolsa drill program will be used as the basis for construction of the reserve block model to be used in the study. The shallow dip of the majority of mineralization in close proximity to the surface and favorable metallurgical characteristics (see news release dated May 21, 2009) suggest a mine plan that will incorporate low-cost open-pit mining in combination with simple heap-leach recovery of gold and silver.
Quality Control and Assurance
All analyses reported are fire assay analyses for gold and multi-acid digestion with AA analyses or fire assay analyses for silver, and completed by either Chemex Labs of Vancouver, Canada, or Inspectorate Labs of Sparks, Nevada. Samples from these intervals were comprised of either HQ or NQ core or reverse-circulation cuttings. All samples were representatively split prior to analysis and transported by the labs to sample preparatory facilities in Hermosillo, Mexico (Chemex) or Durango, Mexico (Inspectorate).
David Linebarger of Sacrison Engineering of Elko, Nevada is the "qualified person" whom has reviewed the database, estimation parameters, block model, and final tabulation for the La Bolsa Resource. Mark Bailey MSc., P.Geo. is the "qualified person" with overall responsibility for the La Bolsa Project and is responsible for the contents of this news release.
