Vancouver, BC – July 22, 2025 – TheNewswire - Vanguard Mining Corp. ("Vanguard" or the "Company") (CSE: UUU | OTC: RECHF | Frankfurt: SL5) is pleased to announce that the Company is preparing for upcoming site visits by the Company’s technical team for core review and analysis in preparation for a maiden NI 43-101 Technical Report on the Company’s Yuty Prometeo Uranium Project (“Yuty Prometeo Project”) in the uranium-rich Parana Basin in southeastern Paraguay.

The four concessions — including the three San Jose and one Yuty Uno concession — collectively span approximately 90,000 hectares (222,395 acres) within the Paraná Basin, which is host to a number of known uranium deposits, including the adjacent Uranium Energy Corp.’s (“UEC”) Yuty Deposit, which contains an Indicated resource of 8.96 million pounds of U₃O₈.1

David Greenway, CEO of Vanguard Mining Corp., commented, “With uranium prices up approximately 33% over the past six months and the spot price now trading at US $78.50 per pound, the sector is experiencing renewed momentum driven by global demand for clean, baseload energy. This is a pivotal moment for uranium explorers, and our timing could not be better.

Our technical team is preparing for its initial site visit to conduct core review, a key step as we advance toward our maiden NI 43-101 Technical Report. This work will include core logging, sampling, and preliminary analysis for validation of historical data and NI 43-101 reporting. These early-stage milestones are critical in demonstrating the geological potential of our Yuty Prometeo Project. Located in the uranium-rich Paraná Basin, and adjacent to a defined multi-million-pound deposit,

our concessions benefit from strong geological fundamentals and excellent infrastructure access. Paraguay remains one of the most underexplored yet highly prospective jurisdictions in the Americas for uranium exploration.

We’re excited to build on the historic exploration and apply modern techniques to unlock what we believe could become a significant uranium asset in South America.”

About the Yuty Prometeo Project

The Yuty Prometeo consists of four (4) concessions—three (3) San Jose Concessions and one (1) Prometeo Concession—covering a combined area of approximately 90,000 hectares (222,395 acres) within the uranium-rich Paraná Basin in southeastern Paraguay.

The Prometeo Concession spans approximately 27,666 hectares (68,368 acres) and is contiguous with UEC’s Yuty Project.

Historical records reference 28 drill holes on the property, with uranium values ranging from 0.05% to 0.10% U₃O₈. The Company cautions that these results are considered historical in nature and have not been verified by the Company or the Qualified Person.

Data from previous work by the Anschutz Corporation suggest that the Prometeo Concession lies geologically on trend with UEC’s  contiguous Yuty Concession.

The San Jose Concessions encompass approximately 62,210 hectares (153,754 acres) across three adjacent claims that are aligned along the Upper Permian–Carboniferous (UPC) contact, a known uranium-hosting geological feature which also hosts UEC’s Yuty, as well as its, as well as its Colonel Oviedo2 ISR Projects. They are approximately 100 km northwest of UEC’s Yuty Project and 40 km west of its Coronel Oviedo Project. A radiometric car survey conducted over a 40 km by 10 km area delineated significant uranium anomalies across the San Jose Concessions.

The Company does not currently have a mineral resource estimate for the Yuty Prometeo Project. A maiden NI 43-101 Technical Report is being prepared.

Note: In Figure 3 below, Vanguard’s concession blocks are labeled ‘Vanguard Mining’ and outlined with black and orange lines. Radiometric anomaly intensity increases progressively from yellow to pink, red, violet, and blue.

About UEC’s Yuty ISR Project1

UEC’s Yuty ISR Project spans approximately 117,359 hectares (290,000 acres) in the Paraná Basin, about 200 km east-southeast of Asunción, Paraguay’s capital. The region hosts multiple known uranium deposits, and Brazil’s Figueira Mine. Preliminary studies suggest the deposit is suitable for in situ recovery (ISR) — the same cost-effective extraction method UEC uses in Texas.1

Exploration at Yuty began in 1976 by Anschutz (Denver), in partnership with Korean and Taiwanese utilities. Over 75,000 meters of drilling were completed before work ceased in 1983 due to falling uranium prices.

CUE Resources Ltd. optioned the project in 2006 and conducted 256 drill holes (31,000 meters) between 2007 and 2010, eventually securing 100% ownership. In 2012, UEC acquired CUE Resources Ltd., gaining full control of the Yuty ISR Project.

UEC’s Resource Estimate

The current disclosed Resource for UEC’s Yuty Project is 8.962 million lbs of U308 Indicated, and 2.203 million lbs of U308 Inferred, which has been reported in a Technical Report prepared for UEC titled “Yuty Uranium Project Initial Assessment US SEC Subpart 1300 Regulation SK Report, Paraguay SA” dated July 1, 2022.1

Vanguard’s management cautions that mineralization on properties adjacent to Vanguard’s projects may not be indicative of mineralization on the Company’s own properties.

About Paraguay

The Republic of Paraguay is an emerging mining jurisdiction in the heart of South America, bordered by Brazil, Argentina, and Bolivia. Known for its political stability, low sovereign risk, and investor-friendly regulatory environment, Paraguay offers a supportive framework for mineral exploration and development. The country has a democratic government, strong legal protections for foreign investment, and a growing interest in unlocking its untapped mineral potential, particularly in uranium, rare earth elements, and base metals. With abundant land, a relatively low population density, and improving infrastructure, Paraguay is increasingly recognized as a geopolitically stable and strategically attractive destination for mining companies seeking long-term growth opportunities.

Non Brokered Private Placements
