Minaurum Drills More High-Grade Silver at Alamos Silver Project
Minaurum Gold Inc. (“Minaurum”) (TSXV:MGG) (OTCQX:MMRGF) is pleased to
announce further results of its 2025 resource-definition drill program targeting the Promontorio,
Travesia, and Europa vein zones at its Alamos Silver Project (“Alamos”) in Sonora, Mexico.
Drilling continued to return numerous high-grade intersections including: (Table 1; Figures 1-4).
• 4.80 m of 287 g/t silver equivalent (“AgEq”) including 0.50 m of 1,029 g/t AgEq (Hole
AL25-141)
• 1.10 m of 730 g/t AgEq (Hole AL25-142)
• 3.08 m of 523 g/t AgEq (Hole AL25-142)
• 1.40 m of 410 g/t AgEq (Hole AL25-148)
“Drilling continues to demonstrate the continuity of high-grade silver mineralization down
dip and along strike” stated Darrell Rader, President and CEO of Minaurum Gold. “At the
Europa stacked vein system , hole AL25 -142 vein intersected three intervals of significant
mineralization, yielding targets for further drilling and resource development.”
2025 Resource-Definition Drilling
Minaurum has completed 35 holes on the Europa, Promontorio, and Travesia vein zones.
Assays have been received for holes AL25 -129 through AL25 -149, with assays pending for the
remainder (Figures 2 and 3).
Promontorio Vein Zone
Promontorio, along with the Europa vein zone, is one of th e high-priority targets in which
Minaurum will establish a maiden resource at Alamos. The 1 km -long Promontorio vein zone
consists of multiple veins including the Veta Grande and Veta Las Guijas veins. Drilling to date
at Promontorio and Promontorio Sur has intersected mineralization in epithermal vein -hosted
cutting volcanic and intrusive rocks in addition to skarn/carbonate replacement (CRD)
mineralization hosted by limestone in the footwall of the vein zones. Hole AL25-141 intersected
4.80 m of 287 g/t AgEq including 0.50 m of 1,029 g/t AgEq (771 g/t Ag, 0.49 g/t Au, 0.49%
Cu, 2.09% Pb, and 4.29% Zn) and 0.55 m of 753 g/t AgEq (352 g/t Ag, 0.495 g/t Au, 0.79%
Cu, 3.10% Pb, and 7.59% Zn) . Hole AL25-147 drilled approximately 200 m to the southeast,
intersected lead- and zinc-mineralized structures within the limestone in the down -dropped
Promontorio Sur zone target, returning 0.55 m of 140 g/t AgEq and 0.25 m of 139 g/t AgEq ,
presenting CRD mineralization continuity with significant potential at depth (Table 1, Figure 2).

Travesia Vein Zone
The Travesia vein zone lies to the north of the Promontorio zone and in the same structural corridor
(Figures 1 and 2). Further drilling is anticipated at Travesia to test potential for high -grade
mineralization along strike and down dip.

intersections.
Europa Vein Zone
Drilling has extended high-grade mineralization down-dip and along-strike (see Minaurum news
release dated October 16, 2025). In the Nueva Europa vein zone, an interval of 1.10 m of 730 g/t
AgEq with high grade silver of 606 g/t Ag including 0.55 m of 1,075 g/t Ag.
Hole AL25-142 returned 4.53 m of 396 g/t AgEq including 0.50 m of 1,271 g/t AgEq containing
983 g/t Ag (0.15 g/t Au, 0.85% Cu, 1.98% Pb, 5.28% Zn); and hole AL25-148 reported 1.40 m
of 410 g/t AgEq. Along-strike and to the south, hole AL25-143 returned 0.90 m of 239 g/t AgEq
and AL25-149 reported 0.70 m of 440 g/t AgEq also containing a high -grade interval of 300
g/t Ag. Drilling continues to step out along strike and down dip at Europa. (Table 1 and Figures
3 and 4).

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
courieror by Company personnel to ALS Minerals' preparation facility in Hermosillo, Sonora, Mexico. ALS prepares
the samples, crushing them to 70% less than 2mm, split ting 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 deviat ion 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 Gold and is independent of the Qualified Person.
