Project History

  • Amax Gold Inc., a subsidiary Amax Inc., bulk mined Hayden based on a shallow, disseminated mineralization model.
  • Historic drilling was limited in scope and depth: 742 holes (327,514 ft), avg. only 441 ft (<150m).
  • Approximately 480,000 ozs of gold and 1.3 million ozs of silver were recovered.
  • Amax Inc. merged with Cyprus in the mid-1990’s which led to the shutdown of Hayden’s operations to focus on copper and molybdenum projects.
  • Kinross acquired Amax Gold in 1998 for three properties — two to develop and one to mine — Kinross did not re-initiate mining or further explore Hayden.

Project Highlights

  • Hayden has not been drill-explored for 29 years.
  • During this period, exploration techniques and understanding of the Low Sulfidation epithermal deposit model have significantly evolved.
  • The Four Nines geological team, through three-dimensional modelling of all available data, has determined that Hayden gold mineralization is structurally controlled and interpreted to be hosted in vein structures exposed at surface to continue at depth.
  • The core of Hayden Hill property is comprised of private lands.

3d Modelling

Four Nines has conducted comprehensive three-dimensional modelling of all available data sets for Hayden Hill:

  • Orange shapes (Shells) enclose grade shells historically mined gold–silver mineralization
  • Shells envelope > 75% of gold-silver mineralized drill intervals and surface samples
  • Mapped epithermal banded veins (green lines) and hydrothermal breccia bodies (blue shapes) correlate well with most of the modeled gold zones indicating strong structural control.
  • Data-indicated gold-silver mineralization present beneath the Shells where gold-silver was mined
  • Geologically-indicated extensions to mineralization also modeled (blue shape)

The Plan

  • Opportunity: Our expert geological team has applied an advanced understanding of Hayden Hill geology, and the low sulfidation epithermal deposit model, to identify significant potential of undeveloped gold and silver mineralization.
  • Objective: Drill to confirm a data-driven understanding of significant mineralization below and peripheral to where gold was mined and revive a past-producing gold and silver mine.
  • Approval:  10 sites at < 1 acres total new disturbance for core drilling.
  • Drillhole Plan:   Drilling will target data-defined and modeled higher-grade mineralization, focusing on key structural corridors and deeper vein extensions.
  • Environmental Considerations:   Maximize current infrastructure and minimize new disturbances.

NOSE TARGET

  • Numerous high-grade values from surface samples, with the highest being 45.4 g/t.
  • The Nose Zone can be drill-explored, at depth, from a location at the bottom of the Lookout Pit (blue star)
  • Historical exploration of mineralized intervals correlates well to the modeled vein surfaces
  • Main NE trending vein set intersected by NW trending veins
  • Hydrothermal breccia bodies (green) along, and at intersection of veins
  • Permitted drill site set to explore at depth

Targets

  • NE trending veins to depth
  • NE-NW vein intersections to depth
  • Hydrothermal breccia bodies

PROVIDENCE PIT

  • Highest gold value for the Providence Zone is 37.9 g/t
  • Hayden Hill historical underground production was from the Golden Eagle veins (anecdotal historical comments of veins 4 – 7 meters wide with gold grades up to 30 g/t)
  • One (1) permitted drill station to explore the intersection of the Providence and Golden Eagle zones and Golden Eagle Zone to depth and along strike.

Targets

  • NE trending veins to depth
  • NE-NW vein intersections to depth
  • Hydrothermal breccia bodies
