The largest concentration of historical drilling has been conducted east of a diabase dyke and has identified four zones of mineralization beginning with the 11650 Zone on the southern edge moving north to the South Zone, Central Zone and North Zone. The North and South Zones have been the most consistent with respect to mineralization running proximal to the Quartz-Feldspar- Porphyry (QFP) intrusion contact. It is still undetermined if the 11650 Zone is an independent zone or a splay of the South Zone as it begins to converge into the South Zone east from the diabase dyke.

Figure 1 is the surface view of the 2024 drill program east of the diabase dike (yellow drill traces) relative to the historical drilling beginning in 1987 up to 2021. Signature's interpretation of the gold zones in the red shading and the QFP body in the yellow shading. Based on the observations from the drill core and the assay results, the gold zones are highlighted on the drill traces in colored rectangles including the newly observed Leopard Zone as well as grade disks representing the assayed results.

As a result of the Spring mapping program and on-going GIS data and drill compilation, the QFP has been interpreted to be an intrusion that bifurcates going from east to west forming a north and south arm. The intervening area between the two arms displays a more fragmented dyke array resulting in a more complex distribution of gold relative to the Central Zone.

As the QFP narrows going eastward, the North, South and Central zones converge in the vicinity of DDH LM24-03. This convergence is important in that, as the zones merge, they form a wider mineralized area. This is reflected in DDH LM24-03 where the hole intersected the three zones from 46.0 metres to 111.0 metres with only three metres between the South and Central Zone and the Central and North Zone. We will gain more insight into this trend as we get results from the additional five holes that have been completed east of the diabase dyke where there has been lower drill density to date. The final six holes of the program are on the west side of the diabase dyke. Two are testing the possible extension of the South Zone and the other four in the area of Shoe Lake where there is also lower density of drilling. These are targeting the west extension of the West Zone.

LM 24-01 and LM 24-02

Historically, drill holes have been collared south of and drilled north to crosscut the strike of the east-west zones nearly perpendicular. The first two holes of the 2024 program, LM 24-01 and LM 24-02, were designed with an oblique orientation drilling from the southwest to the northeast through the area with the highest drilling density, and near the original 1940s underground workings, as recommended by WGM.

LM24-01 is the longest hole of our drilling program with a total length of 460 metres at a dip of -50 degrees and an azimuth of 035 degrees. The hole intersected all four zones. In addition, it was designed to test for mineralization north of a unit of glomeroporphyry (leopard rock - LR). In the past, the LR was used as the footwall to the North Zone and drilling was terminated within a few metres into it. The North Zone is in the mafic volcanics that are sandwiched between the northern edge of the QFP and the LR package, which appears to be coincident with higher grade mineralization. The length of LM 24-01 was also designed to test for mineralization north and well into the LR and intersected a narrow quartz vein-silicified shear with gold mineralization, as can be seen in Table 1: Assay Results.

LM 24-02 was drilled to a total length of 347 metres at a dip of -45 degrees and an azimuth of 035 degrees. The hole intersected mineralization in the Central and North Zones, as can be seen in Table 1. It was not expected to cross the South Zone as it was collared north of the South Zone.

LM 24-03

The third DDH of the program, LM 24-03, was focused on confirmation of past drilling, using hole 88-64 as a twin hole in order provide higher confidence to the 1980s drill results for the resource model. Due to the forest fire in 2021, which swept through the outer margins of the camp, core racks housing the historical and 2018 drilling were destroyed. Therefore, this hole was critical to establish a relationship between the 1988 results and current results. The hole was drilled to a total length of 152 metres and sampled for its entire length with one metre sample lengths, while 88-64 was originally selectively sampled. A complete comparison of the results of the twinning of this hole is pending, and although some of the assay results from 88-64 are higher, in general, grades and lithology mimic each other.

There are several completed holes with results pending that will be providing additional data on the theory of convergence of the main zones to the east.

SGS a certified laboratory and also have 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.

About Signature Resources Ltd.

The Lingman Lake gold property (the "Property") consists of 1,300 staked claims, four freehold fully patented claims and 14 mineral rights patented claims totaling approximately 24,761 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 3-levels at depths of 46-metres, 84-metres and 122-metres. There has been over 28,000 metres of historical drilling done on the Property and four 500-pound bulk samples that averaged 19 grams per tonne of gold. In November 2023, the Ontario government energized a new 115kV high tension transmission line within 40 km of the historic Lingman Lake Mine (https://www.wataypower.ca/).
