Summary and Location

  • Multiple high grade zones in a wide low-grade envelope and favourable topography with pipeline of drill ready targets
  • Drilling to date favourable and encountered significant gold and zinc mineralisation
  • Best intercepts to date include 15 m of 40 g/t Au (DDH MAP-48) and 41 m of 14 g/t Au (DDH MAP-38).
  • Access by paved road to the town of Anzá and a 17 km gravel road operable year-round.
  • Historically secure location. A gypsum mine has been in operation since 1991.
  • Excellent infrastructure, with power grid, abundant water and mine facilities on site.
  • Elevation ranges from 700 m to 2,000 m above sea level.
  • Environmental permit in place to mine underground and open-pit.

History

  • In June 2010, Waymar Resources, acquired by Orosur in July 2014, entered into an option agreement to acquire a 100% interest in the Anzá Project consisting of ~231 km² of mineral rights. 
  • In June 2013, the option was exercised and Waymar acquired a 100% interest in the Anzá project.
  • Total consideration:
    • US$3.8mm cash payments 
    • Issuance of 3.8mm Waymar shares (~1.4mm Orosur shares)
    • Exploration expenditures of US$4.0mm

Geology

  • Multiple phases of alteration, brecciation and mineralization.
  • Multiple mineralised zones hosted preferentially in mudstones, chert and breccias; minor in volcanic units.
  • Pyrite, sphalerite, chalcopyrite, and gold +/-galena, bornite, native S.
  • Anhydrite/gypsum, quartz veining and stockwork, chalcedony, carbonate veinlets.
  • Structurally controlled > 2.5 km long, 200 m wide zone of Au (+/-Ag, Zn, Cu). Variable mineralization and alteration styles. Evidence of “telescoping” (different mineralization styles expected to be vertically zoned but occurring overprinted upon each other).
  • Drilling to date supports significant zinc grades coinciding with high grade gold.

Exploration

  • A fortuitous discovery of massive sulfide lens led to an initial volcanic massive sulphide (“VMS”) model; however, the initial 3,000 meters of phase 1 drilling which began in 2011 did not confirm VMS style mineralization but led to discovery of a new deposit., The mineralization is structurally controlled, with disseminated to semi-massive sulfides, irregular veins, stringers and, hydrothermal breccias. were more than 2 km long, 200 m wide zones of Au (+/‐ Ag, Zn, Cu) showing variable mineralization and alteration styles. An uncertain genetic model in virgin territory with few boundaries on geometry indicates a potential for continued discoveries, with mapped porphyry targets to the north and west, and a postulated porphyry source at shallow depth
  • Exploration Activity and Strategy to date
  • 17,408m of core drilling undertaken (53 holes) since first optioning the Project

  • Drill spacing averaging 50m. Average depths of drill holes of 300m.

  • In excess of 2.5 km of mineralization identified by drilling along the Aragón fault. The deposit is open to the north, south and down-dip.

  • Four high-grade gold zones discovered through step-out drilling.

  • Systematic soil, stream, surface and underground sampling programs

  • 2,867 km helicopter magnetic and radiometric survey completed, covering approximately 260 km²

  • Structural evaluation using Radar images over the entire area of the land package

  • 1:2000 scale geological mapping of areas of interest covering approximately 1,350 ha of the Anzá property

  • Induced polarization (“IP”), resistivity, magnetometry and topographic survey of 30 line-kilometres in a central portion of the Anzá property

Current Efforts

  • Hollistic re-interpretation and in depth analysis of exploration data suite
  • Planning, budgeting and initiation of next step out drilling programme – including further delineation of high grade gold zones
  • Continued advancement of work at targets and work on base metals mineralisatio
