Sirios intersects 105.21 g/t Au over 1.0 m in the Eclipse area, Cheechoo property

MONTREAL, March 05, 2024 - Sirios Resources Inc. (TSX-V: SOI; OTCQB: SIREF) is pleased to report partial results from the first two holes completed as part of the diamond drilling program targeting the high-grade Eclipse zone of the Cheechoo gold property.

Partial results of the first two drill holes

• CH24-305: 105,21 g/t Au over 1.0 m, included in 14.16 g/t Au over 6.4 m, from 251.5 to 257.9 m
  
  
• CH24-306: 24.42 g/t Au over 1.0 m, included in 3.89 g/t Au over 7.0 m, from 312.3 to 319.3 m
  

These two holes intersected the Eclipse zone at the targeted depths, thus confirming its continuity at depth (figure 1).

Considering the positive progress of the current drilling program, Sirios' management has decided to extend the campaign to 2,000 metres.

About the drilling program currently underway at Eclipse
The high-grade Eclipse area, located west of the main area of the Cheechoo gold deposit (Figure 2), is not included in the updated 2022 Mineral Resource Estimation (MRE), which outlined 1.4 Million Ounces of Gold (Indicated) and 500,000 Ounces of Gold (Inferred) (BBA, Mineral Resource Estimate Update for the Cheechoo Project, 20/07/2022). Sirios is currently conducting a drilling program aimed at including Eclipse in the next update of the MRE.

Drill hole CH24-305 was assayed from 230.5 to 280.0 m (end of hole) and hole CH24-306 was assayed from 285.4 to 337.0 m (end of hole). Results are pending for the remainder of the samples from these drill holes.

Analytical quality control
The drill core was described and sampled by Sirios staff at the Cheechoo exploration camp. The core was sawn into two halves, one sent to a certified commercial laboratory for analysis, and the other retained for future reference. Following a strict analytical quality assurance and control program, blanks and certified reference materials were integrated into the sampling sequence. Samples were assayed for gold, on approximately 500g of crushed material, with the Photon Assay™ method (PAAU02) at the MSALABS laboratory located in Val-d'Or. Samples with the presence of visible gold were assayed using the entire sample material with the Photon Assay™ method.
