Signature Resources Drills 8.24 g/t Gold over 2.0 Metres and 7.14 g/t Gold over 2.0 Metres Including 10.10 g/t Gold and 10.50 g/t Gold over 1.0 Metre Respectively, at Its Lingman Lake Project

Toronto, Ontario--(Newsfile Corp. - December 16, 2021) - Signature Resources Ltd. (TSXV: SGU) (OTCQB: SGGTF) (FSE: 3S3) ("Signature" or the "Company") is pleased to announce the most recent set of drilling results from the on-going 10,000-metre diamond drill program at our 100%-owned Lingman Lake Gold Project in Ontario, Canada using our own two diamond drill rigs. These are the final diamond drill results for 2021 and are from drill hole LM21-30 and the Central Zone which continue to extend the known envelope of mineralization for all zones to depth (See Figure 4).

Highlights:

• 8.24 grams-per-tonne gold ("g/t Au") over 2.0 metres ("m") from 90 to 92 metres downhole; including 10.10 g/t Au over 1.0 m from 90 to 91 metres downhole in drill hole LM21-30 in the Central Zone

• 7.14 g/t Au over 2.0 m from 99 to 101 metres downhole; including 10.50 g/t Au over 1.0 m from 99 to 100 metres downhole in drill hole LM21-30 in the Central Zone

"This year's diamond drilling ends with additional strong gold assay results which further extends the high-grade gold mineralization to depth. We expected to intersect the Central Zone on the way to the North Zone target for hole LM21-30 as drilling is planned to intersect multiple zones, per hole drilled where possible. The results from hole LM21-30 come from a broader zone of variable gold mineralization over an 18.0-metre interval which further demonstrates the robust and high-grade nature of the gold zones and overall gold system extending to depth. Signature is extremely well positioned to deliver value to shareholders through exploration and drilling results in 2022. On behalf of the entire Signature Team, we wish you a safe and enjoyable holiday season and Happy New Year." - Robert Vallis, President, CEO, and Director

The current 10,000-metre diamond drill program up to and including LM21-30 is designed to extend the mineralized envelope to depth for the North, South, and Central zones for the purpose of generating a maiden NI 43-101 mineral resource estimate, in late 2022. Additional winter drilling and regional exploration advancements are scheduled to recommence in January 2022 and will benefit from the recently completed geophysical programs. As such, these planned activities will continue to test the extension of all zones to depth and also probe along strike to the east and west.

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 g/t Au with 2.73 gpt 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.
