SIGNATURE RESOURCES REPORTS MORE DRILL RESULTS FROM WINTER DRILL PROGRAM, EXTENDS DEPTH OF NORTH GOLD ZONE 249 METERS

Signature Resources Ltd. has released the results for the diamond drill hole (DDH) LM 25-03, which was part of the company's winter drill program east of the diabase dike that was designed to test the depth extensions of the Lingman Lake deposit. Drilling encountered downdip 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 metres (m).

Signature has completed drilling six DDHs and is 47 per cent complete on the seventh DDH. To date, 3,246 m 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. The company 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 minus 55 degrees and was terminated after it intercepted the Leopard rock unit, which is the footwall for the north zone. LM 25-03 intercepted the three main modelled 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 four m starting at drilling depth of 298 m through 302 m, with an average grade of 0.36 gram per tonne (g/t) gold (Au) including a one 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 one 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 five m section with an average grade of 2.21 g/t Au. The drilling has successfully extended the known mineralization 249 m deeper along the north zone from DDH LM 24-06, which was drilled on the same section. These results warrant further exploration on this section testing the intervals between these two DDHs.

Quality assurance and quality control

Signature Resources maintains an industry standard quality assurance/quality control (QA/QC) program at the Lingman Lake project to ensure sampling and analysis of all exploration work are conducted in accordance with best practices. John Siriunas, PEng, is the independent qualified person under 43-101 who monitors and scrutinizes the results of the QA/QC program.

Assay results from SGS's Burnaby lab for gold and multielement are directly e-mailed to three individuals: Dan Denbow, president and chief executive officer of Signature Resources, Walter Hanych, PGeo, consultant to the company, and John Siriunas, PEng, independent consultant to the company.

SGS is a certified laboratory and also has internal quality control (QC) programs that include insertion of reagent blanks, reference materials and pulp duplicates. The corporation inserts QC samples (blanks and reference materials) at regular intervals to monitor laboratory performance. SGS Canada is the Canadian division of the world's leading testing, inspection and certification company. It provides independent testing and assurance of quality of samples for Signature Resources.

The nominal sampling interval for analyses is one metre and the core was diamond-saw cut (half for sample purposes, half retained for archival purposes) on site to provide a sample of approximately 2.40 kilograms of material per one metre of half NQ-size core. Prior to sampling, all cores are photographed for archival purposes, in sets of three boxes per photo with separate wet and dry versions of each set.

The SGS laboratories carry out the sample login/registration, sample weighing and sample preparation (G_CRU21 -- crush to 75 per cent passing two millimetres; and G_PUL45 -- pulverize 250 grams using Cr-steel bowl to 85 per cent passing 75 micrometres). Gold analyses were performed by (GE_FAA313 -- fire assay preconcentration with AAS (atomic absorption) finish or for overlimit results of more than 10.000 g/t Au; GE_FAG303 -- fire assay preconcentration with a gravimetric finish). The SGS laboratory in Vancouver, B.C., performed multielement analyses for 51 elements (GE_ICM14B -- aqua regia digestion with an ICP-AES (inductively coupled plasma atomic emission spectrometry) or ICP-MS (inductively coupled plasma mass spectrometry) finish). Overlimit analyses for Ag (GO_ICP13B -- aqua regia digestion with an ICP-AES finish) and arsenic (As) or zinc (Zn) (GO_ICP90Q -- sodium peroxide fusion with an ICP-AES finish) were performed as required.

About Signature Resources Ltd.

The company is a Canadian-based advanced stage exploration company focused on expanding the 100-per-cent-owened Lingman Lake gold deposit, located within the prolific Red Lake district in Northwestern Ontario, Canada. The Lingman Lake gold property consists of 1,274 single-cell and 13 multicell staked claims, four freehold fully patented claims and 14 mineral rights patented claims totalling approximately 24,821 hectares. The property includes what has historically been referred to as the Lingman Lake gold mine, an underground substructure consisting of a 126.5-metre shaft, and three levels at depths of 46 metres, 84 metres and 122 metres. There has been over 43,222 metres of drilling done on the property and four 500-pound bulk samples that averaged 19 grams per tonne of gold. The company's initial mineral resource estimate was published in the report, entitled "NI 43-101 Technical Report on the Lingman Lake Property," dated May 31, 2025, prepared by Gehard Kiessling, PGeo, Farshid Ghazanfari, PGeo, Marin Drennan, PEng, Cameron Finlayson and Jeff Plate, CFA, PGeo, of Watts, Griffis and McOuat Geologic Mining Consultants. The initial mineral resource published was estimated to contained 2,145,000 tonnes of material grading 1.38 g/t Au for an estimated 95,200 ounces in the indicated category and 18,398,000 tonnes of material with an average grade of 1.14 g/t Au for an estimated 674,320 ounces in the inferred category at a cut-off grade of 0.30 g/t. The company is focused on rapidly expanding the known mineralized envelope with its 100-per-cent-owned diamond drilling rigs. In November, 2023, Wataynikaneyap Power energized a new 115-kilovolt high-tension transmission line within 40 kilometres of the historic Lingman Lake mine.
