Minaurum Discovers Zinc-Rich Carbonate-Replacement (CRD)
Mineralization at Alamos
Minaurum Gold Inc. (“Minaurum” or “Company”) (TSXV: MGG) (OTCQX:MMRGF) is pleased
to report the discovery of Zinc-rich carbonate-replacement (“CRD”)/skarn mineralization
associated with the Promontorio and Promontorio Sur epithermal silver -zinc-lead-copper-gold
veins at its 100%-owned, fully production-permitted Alamos Silver Project (“Alamos”) in the State
of Sonora, Mexico.
Relogging of existing drill core with a focus on Strategic Metals outlined a continuous 2.4 km-
long zone of Zinc-rich CRD-style mineralization and skarn alteration developed in recrystallized
limestone beneath high-grade silver veins in the Promontorio and Promontorio Sur zones. The
CRD mineralization was never targeted but was cut coincidentally at the bottom of several holes.
Drill holes with the strongest CRD mineralization include:
• Hole AL19-020: 3.21% Zn and 1.05% Pb over 3.0 m
• Hole AL19-024 (800 m southwest of AL19-020): 1.73% Zn and 3.98% Pb over 0.20 m
• Hole AL19-025 (250 m northeast of AL19-020): 2.18% Zn and 0.62% Pb over 7.75 m
“Recognizing that Alamos hosts CRD mineralization in addition to our existing high-grade silver
veins, creates a significant new target for us ,” stated Darrell Rader, President and CEO of
Minaurum Gold . “While carbonate rocks are known throughout the project area, CRD
mineralization has never been directly targeted. We’re especially excited by what’s been found so
far because it lies immediately adjacent to the Promontorio where we hope to block out a resource.
We are adding these CRD targets to our upcoming drill program slated to start as soon as we
complete the current financing.”
“Many of Mexico’s biggest epithermal vein camps, including Fresnillo and Santa Barbara , show
extensive development of zinc -lead-silver CRD and skarn mineralization where the veins cross
limestone. In most cases these manifest as relatively flat -lying sheets (mantos) of massive
sulphides that locally sprout off the veins,” said Dr. Peter Megaw , co -founder and advisor to
Minaurum. “We have strong indications of this along nearly 2.5 km of some of the district’s main
veins. These represent great places to start applying modern CRD exploration approaches to this
system.”
CRD mineralization cut so far at Alamos is characterized by zinc and lead sulfides that replace
recrystallized limestone in the footwall of the Promontorio and Promontorio Sur vein zones (Figure
1). These veins are emplaced along and parallel to north-northeast faults that juxtapose andesitic
agglomerate, recrystallized limestone, and granodiorite. Intersections of this footwall carbonate-
replacement mineralization were reported along with vein mineralization in Minaurum Gold’s
news release dated August 22, 2019 (Table 1), but not pursued due to the company’s focus on
silver and gold.
Lower Cretaceous limestone is the oldest geological unit known at the Alamos project,
stratigraphically underling the Tertiary andesitic volcanic rocks that are the principal epithermal
vein hosts. Limestone crops out extensively on the property in fault -bounded blocks, and drilling
has revealed considerable thicknesses of limestone under the volcanics. The limestone is folded,
so thickness ranges from a few tens of metres to an estimated 400 metres. The district was intruded
by Laramide granodiorite and granite, so the limestone is nearly always strongly recrystallized. In
many areas, particularly those adjacent to the Promontorio and Alessandra vein zones, it is skarn
altered and mineralized , suggesting blind CRD mineralization may be more widely developed
throughout the district.

Sur veins. Hole collar locations, azimuths, inclinations, and depths are listed in Table 2. Collar locations are shown

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 by a licensed
courier 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 50-gram charge. In addition,
analyses are done for a 48-element suite using 4-acid digestion and ICP analysis. Samples with silver values greater
than 100 g/t; and coppe r, 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, 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 laborator y; 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 mate rial 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 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.
