The Macassa mine includes Macassa mine, the nearby Macassa Near Surface ("NSUR") and Amalgamated Kirkland (“AK”) deposits.
NSUR and AK deposits have been incorporated into Macassa's production guidance for 2024 to 2026. Production from the Near Surface deposits commenced in the second quarter of 2023, with processing of the ore at the Macassa mill. The AK deposit has been added to the mining profile starting 2024 with ore forecast to be trucked and processed at the LZ5 mill circuit at the LaRonde complex starting in the second half of 2024.
During the first quarter of 2023, the Company completed the commissioning of Shaft#4. The new four-compartment shaft will have a total hoisting capacity of 4,000 tonnes per day (ore and waste) and is an important component of the plan to increase production at Macassa. |

Summary:
The gold mineralization at Macassa is found along breaks or faults, in veins as quartz filled fractures, as breccias and as sulphide rich (pyrite) zones. There are multiple mineralized breaks, named the ‘04, ‘05, No.6, Kirkland Lake Main and the Kirkland Lake North and South branches. The breaks strike 60 degrees northeast and dip 70 to 80 degrees south in keeping with the Timiskaming trend. The trend of the gold mineralization in the Kirkland Lake camp conforms to the 60 degree westerly plunge of the syenite intrusives.
The South Mine Complex (SMC) was a significant discovery, with the zone having a different character than the zones mined historically at Macassa. The SMC is associated with a cross-over structure that links the ’04 / Main Break with the Amalgamated Break. The mineralization trends parallel to the main structures but has a much flatter dip ranging from 20 to 50 degrees south. SMC mineralization has been found to have greater widths and contain higher grades than the main zones. Considerable potential exists for future exploration drilling to identify additional parallel and stacked zones located above, below and along strike of the known SMC Zone.
The gold mineralization at Macassa is located along the breaks and subordinate splays as individual fracture fill quartz veins, from several centimetres to a few meters thick. Veins may be of single, sheeted, brecciated or stacked morphology. Several generations of quartz deposition are evident ........

Summary:
The Macassa mine includes Macassa mine, the nearby Macassa Near Surface ("NSUR") and Amalgamated Kirkland (“AK”) deposits.
NSUR and AK deposits
At Macassa, mining of the NSUR and AK deposits through existing infrastructure was one of the first strategic optimization opportunities identified at the time of the Merger. Both deposits have now been incorporated into Macassa's production guidance for 2024 to 2026.
The NSUR and AK deposits are accessible from an existing surface ramp at Macassa (the "Portal"). A traditional truck and scoop tram approach has been selected for underground mucking and hauling, similar to the approach at LaRonde Zone 5 ("LZ5"). The deposits will be mined using long-hole open stoping and the stopes will be backfilled using cemented rockfill. At Macassa, the mill is expected to reach its nominal capacity of 1,650 tpd in mid-2024. The LZ5 processing facility at the LaRonde complex, approximately 130 kilometres away, can accommodate the processing of ore from the NSUR and AK deposits starting in the second half of 2024, thus avoiding capital expenditures that would otherwise be required for a mill expansion at Macassa. Production from the NSUR deposit is planned to be processed at the Macassa mill in the first half of 2024 and at the LZ5 processing facility in the second half of 2024. Production from the AK deposit, which is expected to begin in the second half of 2024 with the extraction of a 25,000 tonne bulk sample, is also pl ........
