Laurion Mineral Exploration's Sturgeon River Mine Drilling Continues to Confirm Mineralization

Exciting progress marks LAURION's completion of its Spring 2024 diamond drill program on the Sturgeon River Mine, encompassing 4,289 metres of drilling activity. The results from the initial five drill holes (LME24-041 to LME24-045) have been processed and reported, as detailed in the Corporation's press releases dated May 1, 2024 and May 23, 2024.

Stated Cynthia Le Sueur-Aquin, President and CEO of LAURION: "We are encouraged by what we perceive to be promising results from our Spring 2024 drill program on the Sturgeon River Mine area. The initial five drill holes have provided significant insights into the mineralization of this historic site. Highlights of the latest drill holes, LME24-046 to LME24-048, underscore the potential of the area."

LME24-046 has returned noteworthy intersections, including:

• 2.60 metres at 0.87 g/t Au from 637.00 to 640.60 metres, with a higher-grade interval of 0.60 metres at 3.21 g/t Au.

• 10.25 metres at 0.49 g/t Au from 721.75 to 732.0 metres, including 6.65 metres at 0.70 g/t Au, and 4.10 metres at 0.98 g/t Au.

• Additional intervals of 0.55 metres at 1.68 g/t Au and 0.60 metres at 1.34 g/t Au.

LME24-047 has demonstrated encouraging gold grades with intersections such as:

• 0.50 metres at 5.84 g/t Au from 124.70 to 125.20 metres.

• 1.30 metres at 11.61 g/t Au from 505.30 to 506.50 metres, including 0.50 metres at 52.30 g/t Au.

• Further notable intersections include 0.50 metres at 25.90 g/t Au and 2.00 metres at 2.73 g/t Au.

LME24-048 has also yielded the following encouraging results:

• 1.50 metres at 1.17 g/t Au from 365.50 to 367.00 metres.

• Additional intervals of 0.55 metres at 1.70 g/t Au and 1.50 metres at 1.17 g/t Au.

During this phase of the Spring 2024 drill program, LAURION strategically positioned drill holes LME24-046, LME24-047, and LME24-048 to enhance understanding of the stratigraphic boundaries surrounding the historic Sturgeon River Mine. LME24-046 to 48 effectively probed the stratigraphy to the east and west, covering an extensive area spanning approximately 385 metres. The objective of drill hole LME24-046 was specifically oriented to target the underground workings of the mine. This meticulous approach reflects LAURION's commitment to adopting comprehensive exploration practices, aimed at maximizing insights into potential mineralization.

These results not only validate our exploration strategy but also reinforce our confidence in the significant mineral potential of the Sturgeon River Mine area. As we continue to analyze and interpret the data, we remain dedicated to advancing our understanding of this promising project and creating long-term value for our stakeholders.

A comprehensive prospecting program is in progress for the zones west of the Sturgeon River Mine shaft and the Brenbar Mine areas. The objective is to expand and identify new prospective areas in close proximity to the Sturgeon River Mine Shaft, enhancing the potential for future exploration and drilling.

Sampling and QA/QC Protocols

All core was transported and stored inside the core facility located in Beardmore.

LAURION employs an industry standard system of external standards, blanks and duplicates for all of its sampling, in addition to the QA/QC protocol employed by the laboratory.

After logging, core samples were identified and then cut in half along core axis in the same building, and then zip tied individually in plastic sample bags with a bar code. Approximately five or six of these individual bags were then stacked into a "rice" white material bag and stored on a skid for final shipment to the laboratory.

All core samples were shipped to the ALS facility in Thunder Bay, which were then prepared by ALS Global Geochemistry in Thunder Bay and analyzed by ALS Global Analytical Lab in North Vancouver, British Columbia. Samples are processed by 4-acid digestion and analyzed by fire assay on 50 g pulps and ICP-AES (Inductively-Coupled-Plasma - Atomic-Element-Spectroscopy). Over limit analyses are reprocessed with gravimetric finish. A total of 5% blanks and 5% standard are inserted randomly within all samples. 5% of the best assay result pulps were sent for re-assays. A total of 8.7% blanks and 9.5% standard were randomly inserted during the pXRF analyse of the soil sampling. 2.8% we re-analyzed. All QAQC were verified, and no contamination or bias have been observed.

The remaining half of the core, as well as the unsampled core, were stacked on a skid outside in Beardmore and then transferred to the Sturgeon River Mine site core farm for final storage.
