Highlights:

  • Main Zone Infill Provides Upgrade to Historic Drilling
  • 1.6 g/t Au over 36.3 meters from surface within 66 meters of 1.0 g/t Au (Hole JES-25-105)
  • including 15.2 g/t Au over 1.2 meters, from 35.1 meters depth
  • and 5.8 g/t Au over 3.0 meters, from 9.0 meters depth
  • Mineralization from surface to 97.4 meters averaging 0.7 g/t Au
  • Results Pending for Six Additional Holes


Calgary, Alberta – March 19, 2025 – Tocvan Ventures Corp. (the “Company”) (CSE: TOC; OTCQB: TCVNF; WKN: TV3/A2PE64), is pleased to announce results the latest core drilling at the Gran Pilar Gold Silver Project in mine-friendly Sonora, Mexico. Ten core drillholes totalling 1,167.5 meters were completed earlier this year within the majority owned (51%) Main Zone held in partnership with Colibri Resource Corp. Today’s results are highlighted by 1.6 g/t Au over 36.3 meters from surface, including 15.2 g/t Au over 1.2 and 5.8 g/t Au over 3.0 meters, starting from 9.0 meters vertical depth (JES-25-105). Mineralization correlates with at surface mineralization and lies within a broader anomalous zone drilled that averages 0.7 g/t Au over 97.4 meters. The result from JES-25-105, is a notable improvement from local historic drilling that returned 76.6 meters of 0.5 g/t Au (hole J-7) and 83.8m of 0.5 g/t Au (hole JESP-10), both drilled vertical from surface. To the southeast 100 meters, core hole JES-25-106 returned anomalous mineralization from surface to 122.2 meters depth with the most significant interval returning 3.45 meters of 0.4 g/t Au. Mineralization is known to weaken through this zone. More testing is required to determine the orientation of higher-grade zones known to occur in the area. Results for four core drillholes have now been released, results are pending for the remaining six holes.


“Infill drilling through the Main Zone is identifying precisely where we can source moderate to high-grade ore during pilot and full-scale mining.” commented, CEO Brodie Sutherland. “Positioned directly below surface trenching, we have a high degree of confidence in the extension of significant mineralization at Pilar. We are excited to evaluate the results for the remaining core holes as they will provide insight towards future development along parallel trends across the property. All information will be fed into our planned maiden resource estimate that will look to outline the resource potential across the Main Zone, an important milestone leading towards unlocking the full property potential.”

With gold prices hitting all-time highs, the Company believes the onsite test mine will provide key economic parameters and showcase the mineral potential of the area. In 2023, the Company completed an offsite bulk sample that produced important data showcasing the potential to recover both gold and silver through a variety of methods including heap leach, gravity and agitated leach (see August 22, 2023, news release for more details).



Quality Assurance / Quality Control 

Rock and Drill samples were shipped for sample preparation to ALS Limited in Hermosillo, Sonora, Mexico and for analysis at the ALS laboratory in North Vancouver. The ALS Hermosillo and North Vancouver facilities are ISO 9001 and ISO/IEC 17025 certified. Gold was analyzed using 50-gram nominal weight fire assay with atomic absorption spectroscopy finish. Over limits for gold (>10 g/t), were analyzed using fire assay with a gravimetric finish. Silver and other elements were analyzed using a four-acid digestion with an ICP finish. Over limit analyses for silver (>100 g/t) were re-assayed using an ore-grade four-acid digestion with ICP-AES finish. Control samples comprising certified reference samples and blank samples were systematically inserted into the sample stream and analyzed as part of the Company’s robust quality assurance / quality control protocol.

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

July 16, 2025
NEWS RELEASE - DIEPPE, N.B., July 16, 2025 -- Colibri Resource Corporation (“Colibri” or the “Company”) (CBI: TSX-V) announces its intention to amend certain terms of its currently outstanding 10% unsecured convertible debentures (the “Debentures”) that were originally issued in two tranches by the Company through private placement on August 1 and August 31, 2023 (see the Company’s news releases of August 4, September 12 and September 22, 2023). As at the date hereof, there is US$619,000 of Debentures outstanding. The Company also intends to amend the terms of 3,720,792 outstanding common share purchase warrants (the “Warrants”) and 11,049 finders’ options (the “Finder’s Options”) which were issued in conjunction with the Debentures. The Debentures mature as to US$444,000 on August 1, 2025 and US$175,000 on August 31, 2025 with 10% annual interest payable quarterly and upon maturity. The principal amount of the Debentures are currently convertible into common shares at a price of C$0.50 per Common Share after adjusting for a share consolidation effected on June 13, 2025 (see the Company’s news release dated June 11, 2025). The Debentures carry a fixed foreign exchange rate of C$1.30 for each US$1 of principal for conversion purposes. Interest on the Debentures may not be converted to Common Shares. In respect of the Warrants, each Warrant currently entitles the holder to acquire one Common Share at a price of C$0.60 per share (after adjusting for the aforementioned share consolidation) with 2,637,582 Warrants expiring on August 1, 2025 and 1,083,200 expiring on August 31, 2025. Each Finder’s Options currently entitles the holder to acquire one Common Share at a price of C$0.60 per share (after adjusting for the aforementioned share consolidation) expiring on August 31, 2023. The Company intends to amend the Debentures as follows: The maturity date will be extended for an additional two years to August 1, 2027 and August 31, 2027 respectively and the conversion price will be reduced to C$0.25 per Common Share; alternatively, debenture holders will be offered the option to convert the Debentures at a price of C$0.15 per Common Share on the current maturity date. All other terms of the Debentures remain unchanged. The Company intends to amend the term of the Warrants and the Finder’s Options by extending their expiry date an additional two years and reducing the exercise price to C$0.25. In accordance with TSX Venture Exchange policy, any amended Warrants and Finder’s Options will include an accelerated expiry clause such that the exercise period of the amended Warrants and Finder’s Options will be reduced to 30 days if, for any ten consecutive trading days during the unexpired term of the amended Warrants and Finder’s Options, the closing price of the Company’s Common Shares exceeds $0.30. Insiders of the Company currently hold 135,400 Warrants (the “Insider Warrants”). The application of any amendments to the Insider Warrants constitutes a "related party transaction" within MI 61-101 – Protection of Minority Security Holders in Special Transactions ("MI 61-101") but are exempt from the MI 61-101 valuation and minority approval requirements for related party transactions under sections 5.5(a) and 5.7(1)(a) as neither the fair market value (as determined under MI 61-101) of the subject matter of, nor the fair market value of the consideration for, the transaction, insofar as it involves the Related Parties, exceeds 25% of the Company's market capitalization (as determined under MI 61-101). Any amendments to the Debentures, Warrants and Finder’s options are subject to acceptance of the TSX Venture Exchange. Reasoning for the Proposed Amendments Strategic Timing to Advance Pilar and Drive Shareholder Value The Company is taking proactive steps to strengthen its balance sheet and align capital with its most compelling near-term growth opportunity, the advancement of the Pilar Gold & Silver Project. The Company’s proposed restructuring of the Debentures comes at a pivotal time, as Pilar progresses toward bulk sampling, supported by strong recent and historical exploration results. Momentum Toward Test Mining Colibri’s joint venture partner, Tocvan Ventures, announced on June 18, 2025, that engineering and design for a 50,000-tonne pilot leach facility is now complete, with the permitting process well underway. Tocvan has indicated it does not foresee delays in approvals and intends to commence construction following final permit acceptance. If successful, a pilot test mine run of Pilar materials could generate a relatively meaningful amount of cash flow over a short period, helping to reduce Colibri’s near-term capital requirements and further de-risking its 49% interest in the project. Pilar Drill & Bulk Sample Results Highlight Gold-Silver Potential Over multiple exploration phases, drilling at Pilar has consistently returned broad zones of oxidized near-surface gold mineralization, along with high-grade intercepts—critical for the economics of the upcoming test mine. Highlights include: 2025 (Diamond Drilling – JES-25 Series): 83.5 @ 1.3 g/t Au from surface, including 10.3 g/t over 9.7m 64.9 m @ 1.2 g/t Au, including 3.0 m @ 21.6 g/t Au and 209 g/t Ag—marking the first high-grade intercept along the North Hill trend (JES-25-108) 2023 Bulk Sample: A 1,200-tonne surface sample yielded an average head grade of 1.9 g/t Au with a calculated recovery rate of approximately 62%, confirming the presence of near-surface mineralization amenable to heap leach or vat leach processing. Historical Drilling (2020–2022): 116.9 m @ 1.2 g/t Au, including 10.2 m @ 12.0 g/t Au and 23 g/t Ag (Phase III) 94.6 m @ 1.6 g/t Au, including 9.2 m @ 10.8 g/t Au (Phase I) 47.7 m @ 0.7 g/t Au, including 3.0 m @ 5.6 g/t Au and 22 g/t Ag (Phase II) (Above technical information cited in Tocvan Ventures Corp. news release dated June 18th, 2025 which was reviewed and approved by Brodie A. Sutherland, qualified person for Tocvan Ventures Corp.) Together, these results demonstrate the continuity, scale, and metallurgical potential of gold mineralization at Pilar, while outlining multiple high-grade near-surface zones that could meaningfully contribute to the upcoming bulk test mine. What This Means for Shareholders The pilot plant is nearing approval, and Colibri’s 49% stake positions it to potentially benefit directly from the Pilar’s bulk sample / test phase’s outcome. The restructuring of the Debentures will reduce immediate financial obligations, freeing up capital to support the Pilar bulk sample / test mine program and broader exploration. With gold prices trading near historic highs, the ability to advance a high-grade, near-surface gold system into production under a low-capex pilot structure presents a compelling opportunity to unlock value for shareholders. By aligning its financial position with Pilar’s development timeline, Colibri is taking a disciplined, shareholder-first approach to unlocking value from one of the most advanced gold projects in Sonora. For Debenture holders, they will now have the opportunity to participate significantly in the potential upside in the Pilar Gold & Silver Project.
