Minaurum Commences Phase II Drilling at Alamos Silver Project
Minaurum Gold, Inc (“Minaurum”) announces the commencement of a minimum 20,000-metre Phase II drilling program at its Alamos Silver project in Sonora, Mexico. Phase II involves systematically stepping out from discoveries made during Phase I drilling beginning with two drill rigs. One drill will offset the Europa-Guadalupe discovery hole (AL17-007) which returned 8.25 m grading 1,760 g/t silver (see News Release dated January 18, 2018). The other drill will test targets at Promontorio, both along the vein trend and beneath the Promontorio Mine where recently acquired historical data revealed holes that returned up to 12.2 m grading 710 g/t silver (see News Release dated February 6, 2020).
“We are excited to begin stepping out from our numerous Phase I Drilling discoveries. Phase I confirmed our geological model, proved that Alamos is a silver district and generated a significant inventory of high-grade vein targets for Phase II drilling,” stated Darrell Rader, President and CEO of Minaurum. “We’ll focus first on Europa-Guadalupe and Promontorio as well as the Nueva Europa vein that lies between them. With multiple rigs drilling 75 to 150 m step-outs, we anticipate a considerable amount of news flow over the next 12-18 months.”
Minaurum has set up a system of protocols approved by the Mexican federal, state, and local health authorities to minimize physical contact with surrounding communities and ensure the health and safety of its employees, contractors, families, and local communities. The Phase II program is being conducted from a camp isolated from the community. Personnel will continue to be tested for the presence of the coronavirus and monitored for symptoms on an ongoing basis.
Phase II Drilling
To prioritize Phase II drilling, Minaurum’s technical team divided Alamos’ vein inventory into 3 tiers based on Phase I drilling, recently acquired historical drill information, and surface geological information such as host rocks and structural flexures (Figure 1). Phase II will start with Tier 1 targets, most notably the Europa-Guadalupe vein zone and the Promontorio zone (Table 1, Figure 1, 2, 3, 4, and 5). Tier 2 and Tier 3 vein zones will see drilling later in the program.

Europa-Guadalupe Vein Target
Drilling will begin with step-outs of 75 to 150 m, up- and down-dip, and along strike from the Europa-Guadalupe discovery made in Hole AL 17-007 (Table 2).

Promontorio Vein Target
The Promontorio Mine exploited three principal veins: Veta Guijas, Veta Grande, and Veta del 100 (Figures 4 and 5) and historical reports mention an undeveloped vein lying to the west. Post-mining (1960s-80s) drilling cut significant high-grade mineralization in all three veins more than 50 m below the bottom of the mine over an aggregate 735 m of strike length. Assay highlights from the Promontorio mine underground drilling are in Table 3. Phase II drilling will step-out 75 to 150 m, down-dip and along-strike of the veins at Promontorio.

Nueva Europa Vein Target
Nueva Europa cuts andesitic agglomerate, tuff, and flows; strikes north-northeast and dips steeply east. It has been traced for more than 1,500 m and is open to the north and south. Vein widths range from surface stringers to the vein/breccia zone measuring 1.2 m wide cut in Hole AL17-007 that assayed 542 g/t Ag, 16 ppb Au, 0.28% Cu, 0.44% Pb, and 0.88% Zn. The Nueva Europa vein is hosted in a down-dropped block and consists of quartz-carbonate veinlets and breccia fill. Minaurum believes this indicates that the vein is exposed and cut at a high level and could potentially widen and increase in grade at depth. Down-dip and along-strike step-outs from the AL17-007 intercept will be drilled during Phase II.
Phase I Exploration Wrap-up
Assays have been received for holes AL19-039 and AL19-040, the last two holes of the Alamos Phase I program. These were drilled in the Alessandra vein zone in the eastern part of the project area (Table 4). The highlights were 12.45 m of 0.91% Cu cut in Hole AL19-039.
Holes AL19-039 and AL19-040 were drilled approximately 300 m and 620 m north-northeast of hole AL19-038, respectively. As reported in Minaurum’s January 20, 2020 News Release, Hole AL19-038 cut 6.60 m of 3.89% combined Cu, Pb, and Zn with specular hematite and quartz veining cutting skarn and hornfels.

Stephen R. Maynard, Vice President of Exploration of Minaurum and a Qualified Person as defined by National Instrument 43-101, reviewed and verified the assay data, and has approved the disclosure in this News Release. Historical data reported in this news release has not been verified.
Cautionary Note Regarding Forward Looking Statements: Certain disclosures in this release constitute forward-looking information. In making the forward-looking statements in this release, Minaurum has applied certain factors and assumptions that are based on Minaurum's current beliefs as well as assumptions made by and information currently available to Minaurum. Although Minaurum considers these assumptions to be reasonable based on information currently available to it, they may prove to be incorrect, and the forward-looking statements in this release are subject to numerous risks, uncertainties and other factors that may cause future results to differ materially from those expressed or implied in such forward-looking statements. Readers are cautioned not to place undue reliance on forward-looking statements. Minaurum does not intend, and expressly disclaims any intention or obligation to, update or revise any forward-looking statements whether as a result of new information, future events or otherwise, except as required by law.
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 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, 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.
