LaFleur Minerals Inc. (CSE: LFLR) (OTCQB: LFLRF) (FSE: 3WK0) is pleased to report additional assay results from its regional drilling program on the Swanson Gold Project, led by a near-surface intersection of 6.05 g/t Au over 8.00 metres, including 14.96 g/t Au over 3.00 metres, in hole SW-26-124 at the historical Bartec showing. At Jackson, drilling has extended gold mineralization approximately 1,200 metres west-northwest along strike from the historical showing, and at Jolin, drilling returned multiple mineralized intervals within individual holes. Bartec is now a new priority target, located approximately 5 km from the main Swanson Gold Deposit for follow-up diamond drilling.

BARTEC DRILL HOLE: 6.05 g/t Au over 8.00 metres, including 14.96 g/t Au over 3.00 metres, from 38.00 metres downhole (SW-26-124)

Bartec Target

The Bartec showing is a gold-silver occurrence and associated with the northwest-trending Bartec shear zone, near the contact between felsic volcanic rocks (rhyolite, dacite and felsic tuff) and porphyritic andesite. Mineralization consists of pyrite, native gold, chalcopyrite and native silver, with disseminated mariposite, hosted in quartz-carbonate-sericite veins and veinlets. The host rocks are carbonate-, sericite- and silica-altered, and the showing is interpreted as a shear-hosted, orogenic quartz-carbonate vein system. SIGÉOM records 20 historical diamond drill holes totalling 1,356 metres, completed in 1957, 1959 and 1987. These holes tested approximately 700 metres of strike along the structure. Reported historical intersections include 3.4 g/t Au over 1.5 metres and 2.4 g/t Au over 0.7 metres (GM 05974), and 11.66 g/t Au with 6.86 g/t Ag over 0.2 metres at 110.2 metres downhole in hole 86-1 (GM 45030). These historical results are taken from government assessment files. They have not been verified by the Company’s Qualified Person and are presented for context only.

LaFleur Minerals drill hole SW-26-124 is the first modern-day drill hole to be completed at Bartec since 1987 and was designed to validate and characterize the style of mineralization at the Bartec showing, located approximately 1.3 kilometres northeast of the Jackson showing and 5 kilometres from the main Swanson Gold Deposit. The mineralized interval lies approximately 30 metres below surface.

Given the shallow depth, width and grade of this intersection and the limited modern drilling at Bartec, the showing is now a new priority target within the district-scale Swanson Gold Project for follow-up drilling to test the continuity of the mineralization along strike and down-dip.

REGIONAL DRILLING HIGHLIGHTS AT JOLIN AND JACKSON TARGETS

• 0.58 g/t Au over 19.6 metres (SW-26-103 at Jolin)
• 1.77 g/t Au over 6.45 metres (SW-26-103 at Jolin)
• 0.53 g/t Au over 11.2 metres (SW-26-104 at Jolin)
• 1.45 g/t Au over 7.70 metres (SW-26-111 at Jackson)
• 27.80 g/t Au over 1.0 metre (SW-26-113 at Jackson)
• 0.60 g/t Au over 44.0 metres SW-26-1117 at Jackson)

The regional drilling program forms part of LaFleur Minerals’ broader 25,570.5 metre, 93-hole drilling program at the Swanson Gold Project. The regional drilling program is comprised of 64 holes totalling 16,331 metres. The Company reported results from 29 of those holes on February 4, 2026, and this news release reports results from the remaining 35 holes (9,429 metres) (Figure 1). The regional drilling program tested high-priority targets outside the Swanson Gold Deposit, generated from geological interpretation, airborne magnetic and VLF-EM surveys, ground IP, soil surveys and prospecting. These included the historical Bartec, Jackson, and Jolin showings and several newly identified prospects. Several holes intersected multiple mineralized intervals, indicating that gold mineralization extends beyond the known showings.

Significant assay results from the regional drilling program are presented in Table 1 and Figure 1. Drill collar coordinates and details are presented in Table 2.

Jackson Target

The Jackson area has emerged as an important regional target for follow-up exploration. Thanks to the recent high resolution airborne magnetic and VLF-EM surveys along with recent diamond drilling, the Jackson showing can be traced for 1,500m along strike.

Hole SW-25-40 (disclosed in the Company’s February 4, 2026 news release) was completed in the area of the historical Jackson showing discovered in 1932 and intersected 2.88 g/t Au over 3.65 m. This intersection was followed up with hole SW-25-042 at depth, which intersected 5.78 g/t Au over 2.05 metres.

Hole SW-25-067 (disclosed in the Company’s February 4, 2026 news release) was drilled 1,200 metres west and along strike of the Jackson showing and intersected 51.1 g/t Au over 1.0 metre, demonstrating the potential high-grade nature of the mineralization.

Hole SW-26-111, located approximately 660 metres along strike to the northwest of the historical Jackson showing, and halfway between the high-grade intersection of hole SW-25-067 intersected 1.45 g/t Au over 7.70 metres, including, 3.17 g/t Au over 1.15 metres and 3.30 g/t Au over 1.20 metres.

Hole SW-26-113, located approximately 200 metres southeast of SW-26-111 and 700 metres southeast of SW-25-067, intersected a higher-grade interval of 27.8 g/t Au over 1.0 metre, similar in context to SW-25-067.

Further drilling in the area returned a broad mineralized interval in SW-26-117, located approximately 75 metres northwest of the Jackson showing, which intersected 0.60 g/t Au over 44.0 metres, including 3.41 g/t Au over 2.95 metres.

These results extend gold mineralization well beyond the historical Jackson showing and provide several priority targets for follow-up drilling, including both high-grade and broad zones of mineralization. Additional work will be required to establish the geometry and continuity of the mineralized zones both along strike and at depth.

Jolin Target

LaFleur’s drilling at Jolin has identified multiple mineralized zones within individual drill holes.

Hole SW-26-103 intersected nine separate mineralized zones, including 0.58 g/t Au over 19.6 metres; and approximately 77 metres farther downhole a second significant interval with 1.77 g/t Au over 6.45 metres.

Hole SW-26-104, also located in the Jolin area, intersected seven separate mineralized intervals, including a broad zone of 0.53 g/t Au over 11.2 metres.

The presence of multiple mineralized zones in these holes provides targets for additional drilling to determine the continuity, orientation and extent of the mineralization.

Andrew Elinesky, CEO of LaFleur Minerals, commented: “We are very pleased with these regional drilling results, and Bartec is the standout. Hole SW-26-124 intersected 6.05 g/t Au over 8.00 metres, including 14.96 g/t Au over 3.00 metres, just 30 metres below surface, on a showing that had not seen modern drilling. At Jackson, we have now intersected gold over a 1,200-metre corridor west-northwest of the historical showing, and at Jolin, several holes returned multiple mineralized intervals. Bartec moves straight to the top of our follow-up drilling list. ”

Marc Ducharme, VP Exploration, commented: “We are very encouraged with these latest regional drilling results with several high-grade mineralized gold intervals with significant widths identified across the relatively underexplored regional trends at the Jolin, Bartec, and Jackson targets. Our objective is to explore and expand the potential for large-scale gold mineralized systems through focused exploration drilling programs at the district scale. We are convinced that the Swanson Gold Project has the potential to host several large-scale, gold deposits and our current drilling program is aligned on significantly expanding the existing mineral resource at the main Swanson Gold Deposit.”
