Kirkland Lake Discoveries Encounters Intense

Alteration at Hurricane Intrusive Zone

Toronto, Ontario--(Newsfile Corp. - May 23, 2024) -

Kirkland Lake Discoveries (TSXV: KLDC) (OTC

Pink: KLKLF) ("Kirkland Lake Discoveries" or the "Company")

is pleased to announce the results

from the thirteen drill holes totaling 3,376m that were completed to follow up on surface showings,

mapping, prospecting and ground IP at the Hurricane Intrusive Zone. This fault-bounded zone is located

on the KLD East Side (Figure 1) of the Company's Kirkland Lake project in Kirkland Lake, Ontario. The

Company successfully intercepted wide zones of alteration, quartz veining +/- sulphide mineralization.

This drill program was a progressive step toward understanding and unlocking the geological potential

of the area.

Highlights of drilling

:

Highly altered zone with veining encountered at Whiskey Jack, with a four-metre zone of extremely

bleached mafic volcanics (Figure 2)

Whiskey Jack East drilling intercepted highly altered syenites and feldspar porphyry with intense

quartz veining and increased mineralization associated below the redox boundary defined by the

transition from magnetite to hematite

The mineralized vein found at the Norwood showing was successfully intercepted at depth and

contained visible gold indicating the continuation of the mineralized system at depth

Mineralization at Jensen did not continue below surface

Whiskey Jack Summary

The Whiskey Jack zone at depth consisted of a wide, highly altered zone within mafic volcanics and

gabbro. Alteration within the two holes consisted of strong sericite, calcite, and epidote alteration. Within

these strongly altered zones, there was an increase in at least two generations of veining. One

generation was observed to be wider intersections of quartz, carbonate veins + pyrite, while the other

consisted of quartz carbonate stringers with interstitial hematite alteration. Sulphide mineralization

consisted dominantly of pyrite, which in areas, was semi-massive. To a lesser extent, chalcopyrite was

present.

Whiskey Jack East Summary

Whiskey Jack East drilling consisted of syenite to mafic syenite, with strong, pervasive potassic-

hematite alteration. The top of the hole within the Whiskey Jack East zone was drilled into a magnetic

high, which is interpreted to be related to the patchy magnetite observed throughout the interval. Further

downhole, the magnetite transitioned into specular hematite, coincident with the boundary in the

magnetics from high to low. This represents a redox front and a potential geochemical trap. A significant

intersection of stockwork quartz veining was intersected (Figure 3), representing a wide fluid flow

pathway. Although significant values were not intersected within this stockwork section, this significant

fluid conduit warrants further follow-up.

Norwood Summary

The Norwood showing was drilled to investigate multiple mineralized vein sets determined through

surface grab samples and historic trenching. Hole KLD24-20 successfully intersected one of the

mineralized veins, hosted within a mafic syenite and intercalated mafic volcanics. Within this vein

intersection, fine-grained visible gold was noted establishing that surface mineralization extends to

depth.

QA/QC Protocol

Samples were halved by a core saw with one half being placed into a plastic bag with the sample

number written on the bag and a sample tag placed inside the bag. The plastic bag was then zipped tied

and secured in a locked container until delivery to the lab. Batches of samples were sealed in rice bags

and hand-delivered by KLDC to MSA Labs in Timmins, ON. Samples were crushed to 70% passing

2mm with a riffle split of 500g to place in Photon jar for Photon Assay (gamma ray) for gold only. Another

riffle split of 250g was pulverized to 85% -75 µm for an aqua regia digestion analytical 39 multi-element

ICP-MS method. KLDC inserted OREAS blanks and certified reference materials (OREAS 236 and

153a) into the sampling stream at a rate of 8% (4 blanks and 4 standards per 100 samples). The QA/QC

results from the drilling program and the technical information contained in this news release have been

approved by Mike Kilbourne, P.Geo. who is a Qualified Person as defined in National Instrument 43-

101, Standards of Disclosure for Mineral Projects.
