NEWS RELEASE - DIEPPE, N.B., October 6, 2025 -- Colibri Resource Corporation (“Colibri” or the “Company”) (CBI: TSX-V) is pleased to announce that it intends to conduct two non-brokered private placements as follows: An equity offering (the “Equity Offering”) of up to 8,666,666 units (the “Units”) at a price of $0.15 for gross proceeds of up to $1,300,000. Each Unit will consist of one (1) common share and one (1) common share purchase warrant (the Warrants ). Each Warrant will entitle the holder to acquire one common share (a “Common Share”) of the Company at a price of C$0.25 per Common Share for a period of 24 months. It is anticipated at this time that, of the gross proceeds, approximately $300,000 will be from former debenture holders of the Company whose instruments came due during August 2025 and will not represent new money to the Company. See the Company’s news release of August 6, 2025. The Company is also intending to conduct a non-brokered private placement of up to 250 convertible debenture units (the “Debenture Units”) for gross proceeds of up to US$250,000 (the “Debenture Offering”). Each Debenture Unit consists of one (1) US$1,000 principal amount 10% unsecured convertible debenture (the “Debenture”) and 5,300 Warrants. Each Debenture will bear interest at 10% per annum, calculated in US dollars, from the date of issuance, payable in arrears quarterly and upon maturity or redemption. The Debentures will mature on the date that is two (2) years from the date of issuance (the "Maturity Date"). The Debentures are convertible into Common Shares, at the holder's option, at a price C$0.25 per Common Share (the "Conversion Price") at any time prior to the Maturity Date. For purposes of the Conversion Price, the Debentures carry a fixed foreign exchange rate of C$1.30 for each US$1 of principal. All interest accrued on the Debentures will be payable in cash only and there can be no conversion of the Debenture interest into Common Shares of the Company. Each Warrant will entitle the holder to acquire one Common Share at a price of C$0.25 per Common Share for a period of 24 months following the closing of the offering. A significant portion of the offerings are expected to be acquired by former debenture holders whose loans matured in August 2025 (see the Company’s news release dated August 6, 2025). This will significantly strengthen the Company’s capital structure by converting outstanding obligations into equity-linked securities although this will not represent new money to the Company. Closing of the foregoing offerings is subject to the acceptance of the TSX Venture Exchange (the “Exchange”). Common Shares issuable will be subject to a statutory hold period expiring on the date that is four months and one day after Closing. The Company anticipates that it may pay certain finder’s fees as per the guidelines of the Exchange. The Offering will be conducted by the Company primarily under the "accredited investor" exemption of National Instrument 45-106 –– Prospectus and Registration Exemptions but may use other exemptions if appropriate. Certain insiders of the Company may acquire Units in the Offering. Any participation by insiders in the Private Placement will constitute a "related party transaction" as defined under Multilateral Instrument 61-101 Protection of Minority Security Holders in Special Transactions (“ MI 61-101 ”). The Company expects such participation will be exempt from the formal valuation and minority shareholder approval requirements of MI 61-101 as the fair market value of the Units subscribed for by the insiders, nor the consideration for the Units paid by such insiders, is expected to exceed 25% of the Company's market capitalization. Net proceeds will fund exploration at Colibri’s flagship Mexican gold projects, including Pilar and EP, and for general working capital. “ This financing provides us with the resources to advance key exploration initiatives at Pilar and EP while also strengthening our balance sheet. We view this as a significant step forward that enables us to deliver on important near-term objectives and continue positioning Colibri for growth ,” said Ian McGavney, President & CEO of Colibri.

NEWS RELEASE - DIEPPE, N.B., September 16, 2025 -- Colibri Resource Corporation (“Colibri” or the “Company”) (CBI: TSX-V) is pleased to provide a corporate update, outlining near-term initiatives to advance its 100%-owned EP Gold Project and highlight the significant potential of its 49% interest in the advanced Pilar Gold-Silver Project in Sonora, Mexico. Positioned for Growth in a Strong Precious Metals Market With gold and silver trading near historic highs, Colibri is actively advancing initiatives designed to increase shareholder value. The Company is pursuing a staged growth strategy focused on: Advancing exploration at EP Gold, Supporting development of Pilar, and Strengthening market visibility and corporate positioning. EP Gold Project – District-Scale Potential in the Heart of the Caborca Belt Colibri’s 100%-owned EP Gold Project (Evelyn/Plomo) covers 4,766 hectares in the Caborca Gold Belt of Sonora, Mexico — one of the country’s most prolific mining districts. The Project is strategically located within 25 kilometres of some of Fresnillo Plc’s most significant gold operations, including the producing La Herradura Mine and Noche Buena Mine, as well as the Tajitos deposit (which is reportedly undergoing an updated Preliminary Economic Assessment).

NEWS RELEASE - DIEPPE, N.B., August 19, 2025 -- Colibri Resource Corporation (“Colibri” or the “Company”) (CBI: TSX-V) congratulates its joint venture partner, Tocvan Ventures Corp. (“Tocvan”), on receiving permit approval for a 50,000-tonne pilot mine facility in Sonora, Mexico (announced August 14, 2025). Located in close proximity to the Pilar Gold & Silver Project (“Pilar”), a 49% Colibri – 51% Tocvan joint venture, the facility presents an excellent opportunity to consider processing a bulk sample at a time when gold prices remain near record highs. The permitted facility will be located in very close proximity to the “Pilar Gold & Silver Project “(“Pilar”), a 49% Colibri – 51% Tocvan joint venture. Although no plans have been finalized regarding the use of the facility for Pilar material, its location and scale present a highly compelling opportunity for the partners to consider processing a bulk sample from Pilar in an efficient, cost-effective manner. Pilar is particularly well suited for this purpose: a 1,400‑tonne bulk sample completed in 2023 returned an average head grade of 1.9 g/t Au with recoveries of approximately 62% using simple heap leach methods. Combined with extensive drilling and surface work, sufficient material could be sourced quickly—making Pilar an immediately available, high‑quality feed source for the newly permitted facility at a time when gold prices remain near historical highs. “With a permitted processing facility now secured nearby, Pilar stands out as a ready and logical candidate for a larger bulk sample program,” said Ian McGavney, President & CEO of Colibri. “With a prior bulk sample already delivering an average grade of 1.9 g/t Au and demonstrating recoveries above 60%, and with significant amounts of mineralized material already identified to move quickly, Pilar is clearly positioned for near-term evaluation. Advancing Pilar in this way would be highly advantageous to both Colibri and Tocvan shareholders, particularly with gold trading near all-time highs.” Previously Released Drill Highlights at Pilar (Colibri/Tocvan JV licenses): 2025 Diamond Drilling (all lengths are drilled thicknesses): 83.5 m at 1.3 g/t Au from surface, including 10.3 g/t over 9.7 m 64.9 m at 1.2 g/t Au, including 3.0 m at 21.6 g/t Au and 209 g/t Ag — first high-grade intercept along the North Hill trend 116.9 m at 1.2 g/t Au, including 10.2 m at 12.0 g/t Au and 23 g/t Ag 2024 RC Drilling (all lengths are drilled thicknesses): 42.7m @ 1.0 g/t Au, including 3.1m @ 10.9 g/t Au 56.4m @ 1.0 g/t Au, including 3.1m @ 14.7 g/t Au 16.8m @ 0.8 g/t Au and 19 g/t Ag 2022 Phase III Diamond Drilling (all lengths are drilled thicknesses): 116.9m @ 1.2 g/t Au, including 10.2m @ 12 g/t Au and 23 g/t Ag 108.9m @ 0.8 g/t Au, including 9.4m @ 7.6 g/t Au and 5 g/t Ag 63.4m @ 0.6 g/t Au and 11 g/t Ag, including 29.9m @ 0.9 g/t Au and 18 g/t Ag 2021 Phase II RC Drilling (all lengths are drilled thicknesses): 39.7m @ 1.0 g/t Au, including 1.5m @ 14.6 g/t Au 47.7m @ 0.7 g/t Au including 3m @ 5.6 g/t Au and 22 g/t Ag 29m @ 0.7 g/t Au 35.1m @ 0.7 g/t Au 2020 Phase I RC Drilling Highlights include (all lengths are drilled thicknesses): 94.6m @ 1.6 g/t Au, including 9.2m @ 10.8 g/t Au and 38 g/t Ag; 41.2m @ 1.1 g/t Au, including 3.1m @ 6.0 g/t Au and 12 g/t Ag ; 24.4m @ 2.5 g/t Au and 73 g/t Ag, including 1.5m @ 33.4 g/t Au and 1,090 g/t Ag 15,000m of Historic Core & RC drilling (all lengths are drilled thicknesses): 61.0m @ 0.8 g/t Au 21.0m @ 38.3 g/t Au and 38 g/t Ag 13.0m @ 9.6 g/t Au 9.0m @ 10.2 g/t Au and 46 g/t Ag Pilar Bulk Sample Summary : 62% Recovery of Gold Achieved Over 46-day Leaching Period Head Grade Calculated at 1.9 g/t Au and 7 g/t Ag; Extracted Grade Calculated at 1.2 g/t Au and 3 g/t Ag Bulk Sample Only Included Coarse Fraction of Material (+3/4” to +1/8”) Fine Fraction (-1/8”) Indicates Rapid Recovery with Agitated Leach Agitated Bottle Roll Test Returned Rapid and High Recovery Results : 80% Recovery of Gold and 94% Recovery of Silver after Rapid 24-hour Retention Time Additional Metallurgical Studies: Gravity Recovery with Agitated Leach Results of Five Composite Samples Returned 95 to 99% Recovery of Gold 73 to 97% Recovery of Silver Includes the Recovery of 99% Au and 73% Ag from Drill Core Composite at 120-meter depth
