APRIL 30, 2021, TORONTO, ON – Star Royalties Ltd. (the “Company” or “Star Royalties”) (TSXV: STRR) is pleased to provide an update on its previously announced US$18 million gold purchase and sale agreement (the “Streaming Agreement”) with Arizona Gold Corp. (“Arizona Gold”) (TSX: AZG, OTC: AGAUF) (formerly Kerr Mines Inc.) which will be used to finance the restart of underground operations and gold production at the Copperstone Gold Mine (“Copperstone”) in Arizona, USA.

Restart Activities
As previously disclosed by Arizona Gold, Copperstone remains on track for operational restart in Q4 2021 and first gold production in Q1 2022. Arizona Gold is currently focused on securing long-term lead items, recruiting key personnel, finalising detailed engineering for the mine and mill, and sourcing underground mining contractors and equipment.

  • Final engineering: Arizona Gold has secured several key mining consultants and is finalising details to prepare for operational restart. Underground mining-related ongoing work includes final recommendations in the areas of backfill design, geotechnical, ventilation, water management and electrical infrastructure.
  • Backfill and ground control: Preliminary conclusions from geotechnical studies have indicated the opportunity for wider mining widths than originally contemplated by Arizona Gold. In addition, preliminary results from backfill testing support utilisation of a partially cemented rock backfill process. Arizona Gold has stated that it believes that these conclusions have the potential to enhance previously estimated production efficiencies.
  • Mine engineering: Final mine design and schedules are being prepared in advance of the forthcoming reserve update and ramp-up to full mine production. Considerations in the design and schedule include optimising work flows and implementing newly identified advantages related to ore sequencing, production efficiencies, haul profiles and advancement of utilities, including ventilation.
  • Mine operations: Arizona Gold has initiated pre-production mine ground support rehabilitation and will soon begin stope definition drilling, which is a requirement for detailed final gold ore stope designs. Arizona Gold is in final preparations to engage an experienced underground mine contractor.
  • Mineral processing plant: Work completed in concert with Hanlon Engineering, Arizona Gold’s EPCM contractor, includes final layout and design of the new Whole Ore Leach (“WOL”) gold processing plant. Arizona Gold has completed final costing for the rehabilitation of the existing mineral processing facility’s crush and grind circuit. Final metallurgical testing to optimise grind size, leach kinetics and reagent consumption is nearly complete. In addition, work has begun to remove the original flotation circuit, clearing the way for the forthcoming installation of the new WOL circuit, including a gold doré room.

Drilling Program
Arizona Gold announced on April 27, 2021 the completion of their underground core hole drilling program, having successfully tested the continuity of near-infrastructure mineralisation in various previously defined mineral domains and previously planned stopes. The core drilling was done in the C and D Zones. Preliminary indications confirm mineralisation as previously modelled while demonstrating continuity and extension of currently defined mineralised domains.

Recent drilling highlights include (the dates noted below refer to the dates of the applicable Arizona Gold news releases):

  • AZG-21-P3C-06C (April 27, 2021): 10.8m at 8.2 g/t Au, including 0.7m at 49.1 g/t Au.
  • AZG 21-P3A-02C (April 27, 2021): 2.3m at 10.6 g/t Au, including 0.8m at 19.0 g/t Au.
  • AZG-21-13-12 (April 7, 2021): 1.5m at 22.07 g/t Au, and 1.2m at 11.73 g/t Au.
  • AZG-20S-23 (April 7, 2021): 15.2m at 3.27 g/t Au, including 6.1m at 6.02 g/t Au.
  • AZG-21-13-07 (March 10, 2021): 1.8m at 43.97 g/t Au, and 1.5m at 2.64 g/t Au.
  • AZG-21-21-24 (March 10, 2021): 3.0m at 18.73 g/t Au, including 1.5 m at 26.93 g/t Au.

Reverse circulation close-spaced in-fill drilling is expected to commence in May in order to provide detailed information for stope mining design. Arizona Gold has stated that it expects to provide an updated resource estimate in Q2 2021, which will also include drilling results from their 5,000-metre drilling program in 2019.

Copperstone Gold Stream Final Instalment
The US$18 million advance payment under the Streaming Agreement is being provided in three equal instalments, with the first two US$6 million instalments having now been advanced. As described above, these first two instalments, totalling US$12 million, are being allocated by Arizona Gold to advance detailed engineering, secure long-term lead equipment, perform pre-operational mining activities and to prepare the plant area for the installation of the new WOL processing equipment. Given the current spending profile, which remains back-end weighted, Star Royalties and Arizona Gold have agreed to revise the final US$6 million instalment to be payable on or before June 30, 2021 (previously April 30, 2021), subject to certain closing conditions.

Alex Pernin, Chief Executive Officer of Star Royalties, commented: “We are pleased with Arizona Gold’s prudent capital allocation of our stream financing thus far and are encouraged with Arizona Gold’s restart activities and drilling program results announced to date. Copperstone remains on schedule and on budget for first gold production in Q1 2022. The Copperstone gold stream continues to represent significant, near-term cash flow for Star Royalties from a highly prospective deposit in a world-class jurisdiction.”
