Signature Resources Releases Preliminary Interpretation of Detailed Geophysical Results at Its Lingman Lake Project; Six New Targets Identified

Toronto, October 14, 2021 - Signature Resources Ltd. (TSXV: SGU) (OTCQB: SGGTF) (FSE: 3S3) ("Signature" or the "Company") is pleased to announce preliminary interpretations of the magnetic and resistivity data from its recently completed surveys of the Lingman Lake mine site area (figures 1 and 2).

Magnetometer Survey Highlights:

• Strong edge correlation of linear magnetic high areas with North, Central and South zones.

• Correlation used to identify six new target areas ranging in interpreted strike lengths from 200-metres to more than 950-metres.

• High priority target consists of:

a) complex northeast trending linears extending from the known North and South zones strike extensions as well as north and south of these areas and

b) complex northwest trending linear representing an extension of the West zone. Geophysical and geological compilations of high priority target areas progressing to identify new drill targets for drilling this Fall.

Resistivity Survey Highlights:

• Apparent resistivity component of the induced polarization survey in plan view correlates with magnetic data.
• Strong edge correlation of North, Central and South zones with resistivity high areas mimics the spatial association of the zones with quartz-feldspar intrusion and magnetic high areas.
• Association points to a significant target area along strike of these zones.

"While these interpretations are preliminary, pending further modelling, this is an exciting data-driven development in the exploration of the Lingman Lake gold zones. Extrapolating the zones eastward for more than 500-metres, offers the potential for a new discovery. We are eager to drill test this target area and possibly some of the other areas upon further modelling being completed this Fall."

Robert Vallis - President, CEO, and Director

H2/21 Drilling and Regional Exploration Update:
As highlighted in the September 20, 2021 press release the Company's ongoing, fully-funded Fall 2021 diamond drill campaign continues at the mine site and is currently testing inter-level continuity and grade extensions. First assay results are pending.

Regional exploration efforts continue with the nearly-completed data processing of the completed regional airborne geophysical survey of Signatures entire land package. High-potential target identification and ranking will follow to determine the top three targets for next step winter ground-based surveys followed by target drill testing in H1 2022.

About Signature
The Lingman Lake gold property consists of 1,434 staked claims, four freehold fully patented claims and 14 mineral rights patented claims totaling approximately 27,113 hectares. The property hosts an historical estimate of 234,684 oz of gold* (1,063,904 tonnes grading 6.86 grams-per-tonne ("g/t") with 2.73 g/t cut-off) and 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 46-metres, 84-metres and 122-metres depths.

*This historical resource estimate is based on prior data and reports obtained and prepared by previous operators, and information provided by governmental authorities. A Qualified Person has not done sufficient work to verify the classification of the mineral resource estimates in accordance with current CIM categories. The Company is not treating the historical estimate as a current NI 43-101 mineral resource estimate. Establishing a current mineral resource estimate on the Lingman Lake deposit will require further evaluation, which the Company and its consultants intend to complete in due course. Additional information regarding historical resource estimates is available in the technical report entitled, "Technical Report on the Lingman Lake Gold Property" dated January 31, 2020, prepared by John M. Siriunas, P.Eng. and Walter Hanych, P.Geo., available on the Company's SEDAR profile at www.sedar.com.
