Montaña de Oro


The Montaña de Oro project totals 25,983 hectares and is located in the Sierra Madre Gold-Silver Belt of northwestern Mexico, a prolific gold-silver belt with a history of mining dating back several hundred years.  Montaña de Oro lies in an ENE trend which includes Pan American Silver’s Alamo Dorado mine and Goldcorp’s El Sauzel mine.  A total of 22 targets have been identified to date, including: 17 areas of gold mineralization, a carbonate replacement discovery, and 4 undrilled copper porphyries.  The property is underlain by the Guerrero Terrane which consists of Late Jurassic to Early Cretaceous andesitic flows interbedded with andesitic tuffs and minor carbonate sedimentary rocks and sandstone.  There are three distinct styles of mineralization: low sulphidation Au-Ag, porphyry-related Cu-Mo-Ag mineralization with an Au signature, and contact metasomatic skarn deposits with distinct base metal (Pb+Zn) tenors.  This is a favorable location for mine development with respect  infrastructure and local resources.  Historical work includes 150 drill holes for 39,833 meters by West Timmins Mining.


La Dura West (Cu-Ag)

The La Dura West prospect features copper-silver porphyry related geochemistry, and alkaline style of alteration.  The zone, as it has been drill tested over approximately 1,600m x 600m, north to south.  Cu-Ag porphyry signature is composed of multiple intrusions: tonalite, microtonalite, quartz monzonite porphyry, andesite porphyry and granodiorite
Historical drill highlights include:

  • 73.2m of 0.4% Cu, 3.49g/t Ag, and 0.057g/t Au in hole LC08-029 within 267m of 0.23% Cu, 2.74g/t Ag & 0.04g/t Au starting at 16.75m
  • 25m of 0.047% Mo & 0.11% Cu within 216.6m of 0.022% Mo, 0.076% Cu, & 1.98g/t Ag in LC08-040

La Concepción (Zn-Cu-Ag-Au)

The La Concepción prospect is a carbonate-replacement massive sulphide / breccia Zn-Cu-Ag-Au system located within the La Dura West prospect.  Mineralization occurs as massive sulphide replacements floored by Au-Ag rich siliceous breccias.  The zone, as it has been drill delineated to date, is approx. 200m x 100m, though offset by faulting.  There is a strong IP anomaly associated with fault offset to northeast.  The breccia zone to the south has strike length in excess of 600m exposed with widths of 50 to 150m.  Highlights from historical drill holes:

  • 31.16m of 6.7% Zn, 0.94% Cu, 51.48g/t Ag, 0.80g/t Au in DDH LC07-15
  • 8.18m of 11.06% Zn, 0.81% Cu, 20.65g/t Ag, and 0.18g/t Au in DDH LC07-17
  • 15.45m of 5.96% Zn, 0.49% Cu, 25.49g/t Ag, and 0.54g/t Au in DDH LC07-07
  • 12.3m of 0.32% Zn, 0.6% Cu, 2.074g/t Au, & 66.2g/t Ag in DDH LC08-27

Abundant historic placer gold associated with IP anomaly and projected massive sulphide fault offset.

La Dura East (Zn-Ag-Cu)

The La Dura East prospect is a Zn-Ag-Cu Skarn located 1.4 kilometers east of La Concepción on the periphery of the large La Dura West porphyry copper system.  Limestone-hosted alteration can be traced for 2.5km at surface, then 0.8km further south with Cu-Au and magnetite skarn

Three areas of interest have been identified through past drilling (Lake Shore Gold): La Dura North, Nariz, and La Dura South.

  • La Dura North intercepts include 13.78m of 5.65% Zn+Pb with 23.51g/t Ag and 3.05m of 10.81% Zn+Pb with 42.29g/t Ag
  • Nariz intercepts include 44.2m of 0.15% Zn
  • La Dura South intercepts include 13.27m of 2.01% Zn+Pb with 6.87g/t Ag and 95.71m of 2.51% Zn+Pb with 8.81g/t Ag

El Rodeo (Au-Ag)

The El Rodeo prospect is made up of a bonanza grade epithermal vein cluster with multiple targets.  The zone is comprised of epithermal stockworks, breccias and a network of quartz veins hosted in andesite.  It is located mainly along the regional scale El Rodeo fault system which include multiple sites of high-grade past production.  Targets include:

  • El Rodeo: vein widths of 0.3 to 6.0m over 1,500m strike length, historical drill testing intersected 4.80m of 9.58g/t Au and 121.78g/t Ag
