McGarry Project

Overview

The McGarry Project hosts high-grade, high-value ounces directly along strike from the historic Kerr Addison Mine, one of Canada’s most prolific gold producers with 11–12 million ounces mined at roughly 9 g/t gold. McGarry’s mineralization includes the Kerr Deep Zone—an extension of the Kerr Addison system—and demonstrates exceptional grades from both historical mining (2012) and extensive drilling not yet incorporated into the current resource model. With near-surface gold on trend toward Gold Candle’s open-pit development and multiple underground-ready zones, McGarry represents a rare combination of grade, scale, and accessibility in the Kirkland Lake region.

Location and Infrastructure

McGarry is ideally situated on the prolific Cadillac–Larder Lake Break, adjacent to Gold Candle’s developing open-pit project and directly along strike from the 12 Moz Kerr Addison Mine. The property benefits from significant existing infrastructure, including a fully developed shaft that provides low-capex underground access to high-grade zones such as the Kerr Deep Zone. The project also enjoys road access, grid power, and proximity to the mining services hub of Kirkland Lake, enabling rapid advancement and cost-efficient development pathways.

McGarry Tailings

McGarry hosts the largest tailings deposit in the Kirkland Lake camp, offering a major near-term reprocessing opportunity. These surface-accessible, “shovel-ready” in-situ ounces sit beside Kerr Addison’s ~40 million tonnes of historic tailings. Modern metallurgical testing by Gold Candle on Kerr Addison material demonstrates recoveries of 70–90%, providing a strong analogue for McGarry’s tailings strategy. Next steps include defining tonnage, grade, and recoveries to advance a clear reprocessing plan.

McGarry Resource

The McGarry Property hosts a historical mineral resource, outlined in a 2011 PEA prepared for Armistice Resources (later Kerr Mines). The study reported 447,000 tonnes grading 7.89 g/t gold for 112,000 ounces in the Indicated category, and an additional 157,000 tonnes grading 5.83 g/t gold for 29,000 ounces in the Inferred category. The estimate used a 3.43 g/t Au cut-off, capped assays at 51.4 g/t Au, applied a specific gravity of 2.79, and incorporated a minimum mining width of 1.5 metres. The full technical report and its amended version (September 30, 2011) are available on SEDAR under Kerr Mines Inc. These mineral resource estimates are historical in nature and should not be relied upon without further verification.

McGarry was in underground production and active exploration as recently as 2013, with Kerr/Armistice investing heavily in upgrading site infrastructure—including the shaft, hoist, and underground development. Underground exploration during this period returned exceptional diluted grades over long strike lengths, such as:

  • 8.2 g/t Au over 98 m (1.5 m width)

  • 4.6 g/t Au over 26 m (1.3 m width)

  • 7.6 g/t Au over 79.2 m (1.4 m width)

  • 11.1 g/t Au over 24 m (1.7 m width)

  • 6.1 g/t Au over 7.6 m (1.2 m width)

  • 4.3 g/t Au over 7.6 m (1.8 m width)

  • 6.2 g/t Au over 18 m (1.6 m width)

These results—reported with 35% dilution and disclosed in Kerr Mines’ April 22, 2013 news release (available on SEDAR)—highlight the strong grade continuity and underground development potential across multiple zones.

Barber-Larder Open Pit

The McGarry Property also hosts the Barber-Larder open pit that produced 70,000 tonnes of materials. Approximately 51,000 tonnes were processed at the Kerr Mill, which returned 6,700 ounces of gold for an average reconciled grade of 4.1 gpt gold (see MNDM AFRI file 32D04SE0006).  This property area and its historical production are distinct from, although abutting, the McGarry shaft zone's production and resources.
