Signature Resources Reports More Drill Results from Winter Drill Program, Extends Depth of North Gold Zone 249 MetersToronto, Ontario--(Newsfile Corp. - April 13, 2026) - Signature Resources Ltd. (TSXV: SGU) (OTCQB: SGGTF) (FSE: 3S30) ("Signature" or the "Company") is pleased to announce the results for the diamond drillhole ("DDH") LM 25-03 which was part of our winter drill program east of the diabase dyke that was designed to test the depth extensions of the Lingman Lake deposit. Drilling encountered down dip extensions of all three zones known (South, Central and North) supporting the geologic model. LM 25-03 has successfully extended the depth of the North Zone by 249 meters ("m").

Signature has completed drilling six DDH's and is 47% complete on the seventh DDH. To date 3,246 m's of drilling have been completed. Samples for DDH LM 25-04 and LM 25-05 have been prepared and delivered to SGS Burnaby and are pending assay results. We would expect to have those results in the next 30 days. The remainder of the drill program will be completed shortly and all the remaining core processed and samples shipped for assaying to the SGS Burnaby lab. LM 25-03 was drilled to a total depth of 545 m at a dip of -55 degrees and was terminated after it intercepted the Leopard rock unit which is the footwall for the North Zone. Figure 2 shows that LM 25-03 intercepted the three main modeled gold zones reinforcing the geological model. Assay results for LM 25-03 can be seen in Table 1. The South Zone was the narrowest intercept of 4 m starting at drilling depth of 298 m through 302 m with an average grade of 0.36 g/t Au including 1 m intercept of 1.11 g/t Au. The Central Zone was the widest intercept of 34 m averaging 0.33 g/t Au including a 1 m intercept grading 7.37 g/t Au. The North Zone was intercepted at 498 m and continues for 22 m and had an average grade of 0.57 g/t Au. Within the North Zone there is a 5 m section with an average grade of 2.21 g/t Au. Image 1 shows three core trays for a portion of the North Zone and the start of the intercept of the Leopard rock unit. As can be seen in Figure...
