FOR RELEASE: February 26, 2026 TRADING SYMBOL TSX.V: MGG
Minaurum Accelerates Exploration at Alamos Silver Project;
Expands to Six Drill Rigs and Reports Additional Results
Minaurum Silver Inc. (“Minaurum” or the “Company”) (TSXV: MGG) (OTCQX:
MMRGF) is pleased to report that six drill rigs are now operating at its Alamos Silver Project
as part of the Phase II - 50,000-metre resource expansion drill program . Minaurum will
continue step-out drilling on vein zones with established resources at Europa and Promontorio-
Travesia, while initiating resource -definition drilling on several additional veins, including San
Jose, Quintera, Cotera-Pulpito, and Minas Nuevas.
Recent step-out drilling at Europa has returned multiple high-grade silver intercepts, including:
0.50 m of 524 g/t silver equivalent (“AgEq”) in hole AL25-172, 0.30 m of 1,032 g/t AgEq in
hole AL25-174 and 1.40 m of 290 g/t AgEq in hole AL25-175. At Travesía-Quintera, step-out
drilling returned 2.55 m of 197 g/t AgEq, including 0.40 m grading 567 g/t AgEq in hole AL25-
173 (see Table 1).
“With the continued success of our step-out drilling at the Europa vein zone, we are pleased
to have expanded our drill fleet from four to six rigs,” stated Darrell Rader, President and CEO
of Minaurum Silver. “Supported by an inferred resource of 55 million ounces AgEq at Alamos
and a fully funded 50,000 -metre resource expansion program currently underway,
Minaurum is well positioned to deliver an updated mineral resource estimate in the second
half of 2026. We anticipate a steady increase in drill results as the expanded fleet advances
the program”
Mineralization at the Europa and Travesia –Quintera zones has intersected high -grade silver over
narrower widths that clearly define the margins of the robust silver shoots. The vein system
displays a well-developed pinch-and-swell geometry along strike and down-dip, characterized by
variations in vein thickness and grade. This continuity is exemplified by Hole AL25 -163 at
Europa, which returned 12.35 metres grading 408 g/t A gEq, including 3.20 metres of 1,277 g/t
AgEq, in a 250 -metre step -out (see Minauru m news release dated February 10, 2026),
demonstrating a potentially large expansion of the mineralized envelope.
At Quintera, drilling continues to intersect mineralization within and surrounding historic
underground workings, as well as in parallel hanging-wall veins and along strike.

Data review and verification: Stephen R. Maynard, Vice President of Exploration of Minaurum and a Qualified
Person (QP) as defined by National Instrument 43 -101, reviewed and verified the assay data, and has approved the
disclosure in this news release. Verification was done by visual inspection of core samples and comparison to assay
results. Assay results have not been checked by re-analysis. No factors were identified that could materially affect the
accuracy or reliability of the data presented in this news release.
Analytical Procedures and Quality Assurance/Quality Control: Preparation and assaying of drilling samples from
Minaurum's Alamos project are done with strict adherence to a Quality Assurance/Quality Control (QA/QC) protocol.
Core samples are sawed in half and then bagged in a secure facility near the site and then shipped either by a licensed
courior by Company personnel to ALS Minerals' preparation facility in Hermosillo, Sonora, Mexico. ALS prepares
the samples, crushing them to 70% less than 2mm, splitti ng off 250g, and pulverizing the split to more than 85%
passing 75 microns. The resulting sample pulps are prepared in Hermosillo and then shipped to Vancouver for
chemical analysis by ALS Minerals. In Vancouver, the pulps are analyzed for gold by fire ass ay and ICP/AES on a
30-gram charge. In addition, analyses are done for silver, copper, lead, and zinc using 4 -acid digestion and ICP
analysis. Samples with silver values greater than 100 g/t; and copper, lead, or zinc values greater than 10,000 ppm
(1%) are re-analyzed using 4-acid digestion and atomic absorption spectrometry (AAS).
Quality-control (QC) samples are inserted in the sample stream every 20 samples on average, and thus represent 5%
of the total samples. QC samples include standards, blanks, and duplicate samples. Standards are pulps that have
been prepared by a third -party laboratory; they have gold, silver, and base -metal values that are established by an
extensive analytical process in which several commercial labs (including ALS Minerals) participate. Standards test
the calibration of the analytical equipment. Blanks are rock material known from prior sampling to contain less than
0.005 ppm gold; they test the sample preparation procedure for cross-sample contamination. In the case of duplicates,
the sample interval is cut in half and then quartered. The first quarter is the original sample, the second becomes the
duplicate. Duplicate samples provide a test of th e reproducibility of assays in the same drilled interval. When final
assays are received, QC sample results are inspected for deviation from accepted values. To date, QC sample
analytical results have fallen in acceptable ranges on the Alamos project.
When final assays are received, QC sample results are inspected for deviation from accepted values by the QP. To
date, QC sample analytical results have fallen in acceptable ranges on the Alamos project.
ALS Minerals is independent of Minaurum Silver and is independent of the Qualified Person.
