NEWS RELEASE
MINAURUM SILVER INC.
FOR RELEASE: March 31, 2026 TRADING SYMBOL TSX.V: MGG
Minaurum Drills High-Grade Silver on the Quintera Vein Zone at the Alamos
Silver Project: 5.30 m of 570 g/t Ag, including 2.50 m of 1,024 g/t Ag and 5.80
m of 581 g/t Ag
Minaurum Silver Inc. (“Minaurum” or the “Company”) (TSXV: MGG) (OTCQX: MMRGF)
is pleased to report high-grade drill results from both the Quintera and Europa Vein Zones, as
part of its ongoing Phase II, 50,000-metre resource expansion program at the Alamos Silver
Project (“Alamos”) in Sonora Mexico.
Highlights include:
 5.30 metres of 570 g/t silver (633 g/t silver equivalent “AgEq”), including 2.50 metres
of 1,024 g/t silver (1,120 AgEq) (Hole AL26-180W)
 5.80 metres of 581 g/t silver (658 g/t AgEq) (Hole AL26-188)
“These drill results at Quintera highlight the strong potential to define and expand high-
grade mineralization in vein zones not included in Minaurum’s initial Mineral Resource
Estimate. At Europa, ongoing step-out drilling to the south continues to demonstrate
excellent continuity, with several high-grade intersections,” stated Darrell Rader, President
and CEO of Minaurum Silver. “With consistent high-grade results across multiple vein zones,
including the newly tested Quintera zone, Minaurum remains on track with its fully funded
50,000-metre drill program and is well positioned to incorporate these results into an
updated mineral resource estimate in the second half of 2026.”
The Quintera vein zone was mined along approximately 800 m of strike length and to depths of
500 m and runs parallel to the Travesia vein zone merging with it to the north. Historical records
indicate that the La Quintera mine closed in 1908 due to a drop on the silver price while still in
mineralization averaging 40 oz/t Ag and 8% Cu (see news release dated December 14, 2016 and
February 6, 2020). Quintera was not included in Minaurum’s inaugural mineral resource estimate
and will be incorporated into the resource update.
Minaurum is operating six drill rigs at the Alamos project, focused on expanding resources along
strike and at depth at the Europa and Promontorio-Travesia vein zones, while also carrying out
resource-definition drilling at San Jose, Quintera, Cotera-Pulpito, and Minas Nuevas (Figure
1).

zone including 1.10 m of 305 g/t Ag (449 g/t AgEq) in hole AL26-185; and 2.35 m of 199 g/t Ag
(251 g/t AgEq), including 0.60 m of 701 g/t Ag (828 g/t AgEq) in hole AL26-186 (Table 2; Figure

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, splitting 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 assay 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 the 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.
