Canterra Minerals Acquires Additional 3.6 km Strike Length of the Valentine Lake Shear Zone Which Hosts All the Gold Deposits at Calibre Mining's Valentine Mine

Vancouver, British Columbia--(Newsfile Corp. - August 15, 2024) - Canterra Minerals Corporation (TSXV: CTM) (OTCQB: CTMCF) ("Canterra" or the "Company") is pleased to announce staking of an additional 3.6 kilometre ("km") segment of the Valentine Lake Shear Zone ("VLSZ"). With the addition of this property Canterra has further consolidated its land position to cover approximately 60 km of strike along the gold-bearing structural corridor (Valentine Lake/ Cape Ray Shear Zone) that hosts Calibre Mining's Valentine gold mine that is currently under construction, located less than 18 km southwest of Canterra's property.

The new claims are located less than 5 km on strike from a number of Canterra's gold in bedrock prospects where previous drilling returned intercepts of 10.0 grams per tonne ("g/t") Au over 5.35 metre ("m") core length, including 49.9 g/t Au over 0.98 m (Antler Gold Inc. news release dated December 13, 2017) and 0.57 g/t Au over 42.0 m core length (see news release dated April 19, 2022). The additional property comprises 47 claims covering 11.75 square kilometres ("km²") (1,175 ha) that is contiguous to Canterra's existing land position.

Highlights:

• Canterra's expanded land position covers ~60 km of the northeast extension of the gold-bearing structural corridor that hosts Calibre's Valentine gold mine ~18 km southwest of Canterra's property.
• Previous work undertaken by Canterra, and past operators have identified multiple gold-in-bedrock prospects within the expanded land position as well as numerous gold-in-soil and till anomalies located proximal to structural breaks highlighted by recent geophysical surveys.
• Given the recent increased profile of central Newfoundland's gold potential with the entry of multiple gold production companies including Calibre Mining at the Valentine Mine, B2Gold as shareholder of AuMega Metals at its Cape Ray deposit , and Eldorado Gold through its option with TRU Precious Metals at Golden Rose, Canterra is well positioned with a district scale property position covering a key portion of this prolific gold bearing structural corridor that isn't yet controlled by a major miner.
• Canterra is initiating drilling on its high-profile Buchans critical minerals project acquired by the Company in December of 2023. This project hosts the past producing Buchans mine, one of the world's highest grade volcanogenic massive sulphide mines.

Chris Pennimpede, President and CEO of Canterra commented: "With M&A in the gold exploration and development space around the world at all-time highs, we are pleased to have further consolidated our land position within this emerging gold mining district. There are numerous new mid-tier and major mining company entrants to this 200 km gold bearing structural corridor, with B2Gold announcing a $3M dollar strategic investment into AuMega Metals² , Eldorado Gold optioning 45 km of the gold-bearing corridor for approximately $15M³, and Calibre Mining acquiring the next 32 km segment of the corridor from Marathon Gold less than a year ago for $345M¹. Calibre have identified ~ 5 Moz¹ and counting, and recently announced the largest exploration drilling program in that project's history. Canterra is in a very exciting position as it owns the next 60 km of this prolific gold corridor extending northeast and along strike of Calibre."

Canterra's New Valentine Lake Shear Zone Gold Project
Canterra's new claims cover ground that has undergone recent exploration that identified several gold-in-soil anomalies that remain untested by diamond drilling, including multi-station anomalies ranging up to 200 m in length and returning values up to 317 ppb Au (Buchans Resources December 14, 2018 news release). Calibre recently announced that it expects to achieve gold production from its deposits located 18 km southwest of Canterra's properties during the second quarter of 2025 and additionally announced a 100,000 metre "resource expansion and discovery drill program" within their adjacent property (Calibre July 15, 2024 news release). Calibre's land position covers a ~32 km segment of the same structural corridor and hosts a substantial gold endowment including 2.7 Moz of Reserves, 3.96 Moz of Measured and Indicated Resources and 1.10 Moz of Inferred Resources¹.

Canterra's VLSZ Gold Projects
Canterra's VLSZ Gold Projects cover 242.5 square kilometres extending over the northeastern extension of prospective gold-bearing structures on strike of Calibre Mining's Valentine gold mining project currently under construction (Figures 1 & 2). To date, Canterra has advanced these projects through early exploration initiatives mostly comprised of property- and regional-scale geochemical and geophysical surveys and limited diamond drilling of several gold-in-bedrock discoveries. Canterra's consolidated land position is held 100% by Canterra and the Company believes this consolidated land position hosts excellent potential for new gold discoveries akin to those at Calibre's Valentine Project.
