Project Details

– Location

Approx. 160 km southwest of city of Salta (Salta province)

– Description

High-sulphidation epithermal silver-gold deposit

– Minerals

Gold - Silver

– Stage

Prefeasibility

– Capital Cost

$255,000,000.00

– Mine Operation

The Project as currently designed will be an open pit mining operation consisting of a single open pit (Oculto); mining is proposed to be carried out by a contractor as a conventional truck and shovel operation.

– Processing

The processing facility(7,000 tpd) has been selected as a conventional silver processing plant that incorporates crushing, grinding, agitated leaching, counter current decantation (CCD), cyanide recovery, Merrill-Crowe zinc precipitation, refining and tailings disposal.

– Average Annual Production
  • 11.4 Moz of silver equivalent (8.0 Moz silver and 44.3 koz gold) in first 5 years;
  • 8.5 Moz of silver equivalent (4.2 Moz silver and 52.0 koz gold) over the Life-of-Mine.
– Remaining Life

16 Years

– Resources & Reserves
  • Measured and Indicated Resource of 53.3 MT grading 87 g/t silver and 0.79 g/t gold containing 148 Moz of Silver and 1.4 Moz of Gold (258 Moz Silver Equiv.)

Additional Comments

Upcoming Milestones and Catalysts:

  1. Q4/23: Prioritize exploration targets for upcoming Phase IV drill campaign (Alpaca, Fantasma, JAC North, etc).
  2. Early Q1/24: Pre-Feasibility Study (“PFS”) completed on Diablillos project.
  3. H1/24: Commence Phase IV step-out drill program, focused on new mineralized zones.
  4. 2025: Definitive Feasibility Study (“DFS”) and Construction Decision

-

  • Excellent Metallurgical Testwork Results: At Oculto, recoveries expected to range between 82% - 86% for silver and 84% - 89% for gold / At JAC & Fantasma, expected recoveries between 86% - 93% for silver and 82% - 91% for gold

  • Extensive Exploration Upside Potential: Future drilling will focus on exploration targets which include: JAC North, Alpaca, and the Oculto-Fantasma trends, each of which has the potential to continue to add additional silver/gold mineralization
