Gamma Resources Expands Uranium Holdings in New Mexico’s Chama Basin Staking increases Mesa Arc Project to over 4,500 acres across historically significant uranium trend
Gamma Resources Expands Uranium Holdings in New Mexico’s Chama Basin
Staking increases Mesa Arc Project to over 4,500 acres
across historically significant uranium trend
Vancouver, British Columbia – July 31st, 2025 – Gamma Resources Ltd. (TSX-V: GAMA; OTCPK:
MLLOF; Frankfurt: MRDN) ("Gamma" or the "Company") is pleased to announce the staking of
185 new federal lode claims, totaling approximately 3,700 acres, in northern New Mexico, USA.
This strategic expansion significantly increases Gamma’s uranium exploration footprint in the
Chama Basin of the prolific Colorado Plateau . These newly acquired claims com plement the
previously leased 41 claims forming the Mesa Arc Project (which is subject to final approval of
the TSX Venture exchange) , an advanced -stage uranium exploration project, which now spans
approximately 4,520 acres.
Highlights of the Mesa Arc Project
• Consolidated land package now covers a district-scale uranium trend
o Project now spans ~4,520 acres, covering a four-mile uranium-mineralized trend.
• Historic Resources with Potential for Expansion
o Over 2.9 million lbs U₃O₈ historically identified across four deposits at a 0.11%
cutoff.
o Grade x thicknesses up to 4.8 were recorded in the deposit areas.1
• High-Grade Potential in the Southern Claim Block:
o Includes intercepts of 10 ft at 1.1% U₃O₈ in areas with no prior resource estimate.2
• Valuable Historical Data
o Access to over 1,000 historic drill holes and gamma-ray probe data.
• Strategic Timing
o Expansion supports growing U.S. demand for secure, domestic uranium amid
clean energy transition.

2 The data disclosed in this press release is related to historical drilling results. GAMA has not undertaken any
independent investigation of the sampling, nor has it independently analyzed the results of the historical
exploration work in order to verify the results. GAMA considers these historical drill results relevant as the
Company is using this data as a guide to plan exploration programs. The Company's current and future
exploration work includes verification of the historical data through drilling. Past drilling results may not be
reflective of future drilling results.

The Project contains deposits totaling over 2.9 million lbs U₃O₈ at a cutoff grade of 0.11% U₃O₈
(see table below).
It is centered on a nearly four -mile-long, northeast -trending mineralized corridor within the
uranium-hosting Jackpile Member of the Jurassic Morrison Formation 3. The trend was originally
explored by Anaconda Mining Corp. (ARCO) and United Nuclear Corporation during the 1960s
and 1970s.

Previous exploration identified substantial uranium deposits, including the:
▪ AR-15 deposit 612,300 lbs U₃O₈
▪ AR-30 deposit 838,400 lbs U₃O₈
▪ AR-205 deposit 346,274 lbs U₃O₈
▪ Section 3 963,000 lbs U₃O₈
▪ Section 4 216,000 lbs U₃O₈
Total: 2.9 million lbs U₃O₈ at a cutoff grade of 0.11% U₃O₈
Grade x thicknesses values up to 4.8 were recorded in the deposit areas. At the southernmost
claim block, a resource was never estimated but saw drilling results of up to 10 feet at 1.1% U₃O₈3.
Claim staking by Gamma has now connected four discrete uranium deposits that remain open
for expansion through targeted step -out drilling and exploration where high -grade results were
never followed up. The Company also has access to comprehensive historical data, including
resource estimates, drill maps, and down -hole gamma -ray p robe data, facilitating efficient
planning for upcoming exploration activities.
Previous operators drilled an estimated 1,000 Reverse Circulation (RC) drill holes. Assuming an
average depth of 250 feet per hole, the total cost of drilling, assaying, and geologic assistance in
today’s dollars could reasonably be estimated to exceed US$10 million, underscoring the
significant historical investment and existing data value of the Mesa Arc project.3
The Company’s decision to further consolidate the land position reflects confidence in
management’s understanding of the mineralization and the growing need for domestic uranium
supply, driven by renewed interest in nuclear energy as an essential, low -carbon power source
vital to achieving climate and energy security goals in the United States.
Mr. Gabriel Alonso-Mendoza, President and CEO, commented, “The staking of these new claims
is an important step forward in advancing the Mesa Arc Uranium Project into one of the most
compelling uranium exploration opportunities in the southwestern U.S. We are building on a
strong foundation of substantial historic data, known high -grade uranium zones, and a
geologically favourable setting. With momentum building behind nuclear energy as a clean,
reliable pillar of the U.S. energy mix, Gamma is well position ed to play a meaningful role in
strengthening the domestic uranium supply chain and supporting the country's long-term energy
security goals.”
About Uranium
In March 2025, President Trump issued Executive Order 14156 formally designating uranium as
a U.S. critical mineral.4 This legal shift empowers federal agencies under the Defense Production
Act to fast -track permitting, direct federal procurement, and prioritize uranium mining,
conversion, enrichment, and fuel fabrication infrastructure across the country. A follow -on
executive package on May 23 accelerated regulatory reform across the nuclear fuel cycle —
including licensing of advanced reactors (Gen III/IV), small modular reactors (SMRs),
microreactors, and establishing a goal of 400 GW of nuclear capacity by 2050 —creating a
supportive policy ecosystem for domestic uranium producers and enabling secure HALEU supply
chains for next-generation reactors5.
Meanwhile, the uranium market is facing a historic supply –demand imbalance. Years of under -
investment and tightened geopolitical trade have compressed inventories and elevated prices.
Spot uranium prices recovered from lows near US $63/lb in early 2025 to over US $78.50/lb by
June, while long-term contracts and forward ceilings continue rising as utilities secure supply.6 At
the same time, nuclear energy is increasingly viewed as a reliable, carbon‑free backbone for both
energy security and climate goals, with Western governments doubling down on nuclear
deployment and investing in domestic fuel chains, SMRs, and advanced reactor technologies. 7
These tailwinds explain why the Company feels strategically positioned in uranium, eager to help
to supply a market poised for structural growth and supported by strong public policy
frameworks.
