El Grande

Project Highlights

  • Expansive property; 11 individual claim blocks covering 550 km2
  • Located in Nayarit state of Mexico, approx. 250km north of Guadalajara
  • Situated on the prolific Sierra Madre Occidental (“SMO”) gold-silver belt
  • Project is under-explored and undrilled
  • On trend with major precious metal mines and deposits 
  • Excellent infrastructure: near major highway, road access, power, rail service, labour, and a nearby port
  • Widespread evidence of gold, and lack of modern exploration provides a unique opportunity to be the first mover in a potential district-scale gold-silver system

District & Regional Potential


  • Mexico has a rich mining history
  • Consistently ranks in the world’s top 10 producing countries for gold, silver, and copper. Other important mineral products include lead, zinc, coal, iron, and graphite
  • Total value of minerals produced in Mexico in 2018 was $US13.5B(1) including precious, non-precious, and industrial minerals
  • Ranked 4th in world for foreign direct investment in mining in 2019 at $US5.47B(2)

Sierra Madre Occidental (SMO) Gold-Silver Belt:

  • 700-1000km long belt from Sonora to Nayarit
  • Geology includes a Lower Volcanic Sequence with a very rich endowment of mineral resources
  • Hosts numerous large scale precious metals mines and deposits

Geology & Mineralization

Mineral Occurrences:

Hosts a collection of under explored mineral occurrences representing a wide range of potential deposit types including:

  • Low sulphidation gold – bulk-tonnage oxide gold targets – Aztlan B, Dolorosa, Los Gallos, San Ramon and San Martin
  • Low sulphidation gold-silver vein system – Los Torres
  • Iron oxide copper – gold – silver targets – Angel Wing

General Geology & Mineralization:

  • Upper Volcanic Sequence minor
  • Lower Volcanic Sequence major
  • Sierra Madre geology is covered by recent Pleistocene cover of the coastal plane to the west
  • Intrusion Related HS Gold Mineralization

5 High-Priority Prospects

El Tule Basin:

  • Basin rimmed on three sides by prominent topographic volcanic ridges of Lower Volcanic Sequence rocks
  • Hosts numerous target areas that largely share a similar set of characteristics
  • Gold and silver mineralization hosted in strongly clay and iron oxide altered sheared and brecciated felsic volcanic rocks with zones of quartz veins and veinlets

Aztlan B and Los Gallos:

  • 1500 m x 300 m soil anomaly was defined on the east side of El Tule Basin, remains under explored and drilled
  • Historic gold grades show a linear trend of Au samples grading +3000 ppb within a larger anomaly area where soil samples return from 200-750 ppb gold


  • Gold mineralization on Dolorosa and contiguous San Martin, and San Ramon claims shares similar geological characteristics to that seen at the historical nearby El Polo mine
  • Hosts a 10m X 30m pit with numerous satellite prospects, and hosts strongly altered and sheared volcanic rock with quartz veinlets
  • Historic assay results for seven of the 90+ trenches on the southern San Martin and San Ramon range from 3-21m strike length and with up to 12.52g/t goldng revealed 11.6 g/T Au  and up to 0.86 oz. / T Au*

Angel Wing:

  • Hosts a shallow shaft, with Au-Cu-Ag mineralization present in a zone of brecciation, including bladed “wing” shaped amethystine crystal clusters
  • 30 to 40 m-wide trench exposes a 10-m-thick quartz vein breccia containing large gossanous clots of massive chalcopyrite and bornite, as well as copper sulphates and specular hematite

Los Torres Epithermal Vein:

  • Undrilled, 4-6km long, 10 to 40 m wide epithermal quartz vein trend
  • Quartz displays barnacle-like textures (“Rollados”) suggestive of formation in a near-surface hot spring environment
  • Quartz textures suggest bonanza gold grades may lie at depth
