The HM claim is part of the Macassa mine complex located in Kirkland Lake, Ontario. The Kirkland Lake mining camp has been a prolific gold producer since mining began there in 1915. Gold mineralization at Macassa is found along breaks or faults, in veins as quartz filled fractures, as sulphide rich pyrite zones and as breccias.

The HM claim is an area that hosts the easterly extension of the South Mine Complex (SMC) and is located southeast of the #2 shaft at the Macassa mine. The exploration results from the SMC and HM Claim have identified a significant new find as some of the veins have larger widths and higher grades than the Macassa main zones. Kirkland Lake Gold is developing a new 4,000 tpd shaft that will support higher levels of production and enable more effective underground exploration east of the SMC. A mid-shaft loading station at approximately 1,650 metres in depth is expected to be completed by 2022.

Mining at Macassa is conducted primarily with overhand and underhand cut-and-fill methods. The Macassa mill was constructed in 1986, originally designed for throughput of 725 tpd but has been upgraded to handle 2,000 tpd. Ore processing at Macassa starts with crushing and grinding before it enters leach tanks for cyanidation and then flows through a carbon-in-pulp circuit, followed by a Merrill- Crow recovery system. The concentrate is melted in a furnace where doré is poured that typically contains 85% to 88% gold.

Recent Activities

July 2018
Kirkland Lake announced high-grade intersections from the continuation of their 2018 infill drilling program at the Macassa mine. The results have identified a high-potential area within the HM Claim, located approximately 560 metres southsoutheast of the new #4 Shaft. Highlighted underground drill results include:

  • Hole 53-3453: 3.7 metres of 34.6 g/t gold from 222.2 metres;
  • Hole 53-3455: 3.9 metres of 38.4 g/t gold from 220.4 metres; and
  • Hole 53-3466: 3.6 metres of 65.5 g/t gold from 218.7 metres.

January 2018
Kirkland Lake announced that the development of a new 4,000 tpd shaft will begin during 2018. The shaft will reach depths of approximately 2,100 metres and will support higher levels of production and enable more effective underground exploration to the east of the South Mine Complex where the HM Claim is located.
