Minaurum Discovers Virgin Silver - Copper Skarn Zone and Extends Europa-Guadalupe Vein Strike to 800 Metres at Alamos Silver Project

November 9, 2021

Minaurum Gold, Inc (“Minaurum”) is pleased to announce results from its on-going Phase II drilling program at its Alamos silver project in Sonora, Mexico. Drilling at the Alessandra vein recently discovered a blind Ag-Cu-Pb-Zn skarn that is open in all directions while ongoing drilling at Europa-Guadalupe continues to delineate a high-grade mineralized vein system which is now been extended by 40% to at least 800 meters in length.  Europa-Guadalupe remains open at depth and along strike.

Highlights include

Alessandra skarn/vein zone

  • AL21-085: 11.05 m @ 120 g/t Ag, 1.12% Cu, 0.37% Pb, and 1.79% Zn; including 5.45 m @ 183 g/t Ag, 1.65% Cu and 2.49% Zn

Europa-Guadalupe vein zone

  • AL21-080:  1.60 m @ 174 g/t Ag and 1.30% Cu, including 0.75 m @ 297 g/t Ag and 1.88% Cu
  • AL21-083:  1.60 m @ 247 g/t Ag, including 0.45 m @ 589 g/t Ag
  • AL21-083:  2.25 m @ 228 g/t Ag, including 0.50 m @ 754 g/t Ag
  • AL21-084:  1.55 m @ 139 g/t Ag, including 0.25 m @ 777 g/t Ag
  • AL21-084:  1.65 m @ 240 g/t Ag, including 0.60 m @ 547 g/t Ag and 0.72% Cu

“Our strategy of drilling sizable step-outs continues to return excellent hit rates as we discovered both a significant new polymetallic skarn system at the Alessandra target in addition to expanding the mineralized strike of the Europa-Guadalupe vein system by 40%,” stated Darrell Rader, Minaurum President and CEO.  “With both targets remaining open along strike and at depth, we look forward to updating the market as drilling continues.”

David M. Jones, Director of Minaurum Gold and skarn expert commented, “The discovery of a blind silver-gold-copper skarn is a testament to Minaurum’s commitment to enhancing shareholder value through aggressive exploration.  We made the decision to return to the Alessandra vein target based on the recognition of pathfinder elements which we deduced might lie above a mineralized body and now we have demonstrated that this concept was correct.  Alessandra has the right host rocks (reactive limestones), the right intrusions (large mafic dikes) and the target is completely open with no known prior mining history.”

Alessandra Skarn and Vein Zone
Hole AL21-085 cut a 11.05-m mineralized zone at a vertical depth of approximately 450 m in skarn-altered limestone in the footwall of the Alessandra fault about 230 m south of and 280 m below the mineralized intersection of hole AL19-038 (4.20 m of 2.58% Cu, 0.63% Pb, and 2.17% Zn) (see News Release dated January 20, 2020). 

Characterized by strong retrograde alteration of garnet-diopside skarn, the AL21-85 intercept displays a down-dip increase in silver and gold grades and the continuation of strong copper and zinc grades.  The increase in silver values, from nearly absent in surface exposures and previous drilling at Alessandra, along with strongly anomalous levels of arsenic, bismuth, and tellurium in the mineralized intercept, suggest potential for increased precious-metal mineralization at depth.  The Alessandra vein zone extends for one kilometre of strike.

Hole AL21-090 was drilled from the same collar as AL21-085, but at a shallower angle in order to test the zone up dip (Figures 2 and 3).  Assay results are pending for hole AL21-090 while drilling at Alessandra continues.

Europa-Guadalupe Vein Zone
Holes AL21-080, -082, -083, and -084 were drilled in the northern part of the Europa-Guadalupe vein zone, to test for extension of mineralization found in holes in the central part of the zone (see News Releases dated January 18, 2018, August 22, 2019, and September 24, 2020).  Holes AL21-086, -087, and -088 drilled in the south-central part of the Europa-Guadalupe vein zone.

Drilling shows that vein mineralization continues along the vein zone and indicates that the vein is open along strike and down-dip.  Hole AL19-028 targeted the vein about 220 m north of the AL21-083 intercept and roughly 150 m up-dip.  The vein is open below and to the north of the -028 intersection.  See Table 1 for drill highlights and Figures 4 and 5 for locations of drill intercepts.

Three more holes, AL21-086, -087, and -088 were completed in the south-central part of the Europa zone.  Hole AL21-086 encountered significant mineralization in the granodiorite footwall of the andesite/granodiorite contact.  AL21-088 cut a 21.85-m-wide zone of mineralization that included a 0.40-m section grading 304 g/t Ag in the immediate hanging wall of the contact.

Ana Vein zone
Hole AL21-081 was drilled to test the Ana vein/fault zone, in particular the area around the intercept reported in hole AL18-011 (see News Release dated March 1, 2019).  AL21-081 cut numerous bands of altered limestone-hosted Zn mineralization.  The highest grades reported were 0.69% Pb and 2.18% Zn over 0.55 m. 

Promontorio Vein Zone
Minaurum is rehabilitating the Promontorio adit, to gain access for geological mapping and to pump water for drilling from the mine’s lower workings.  The Promontorio adit is reported to be 1,200 metres long, with at least two levels below the main access adit.  Geological mapping of the workings, combined with historical drill results (see News Release dated February 6, 2020) will aid in further drill targeting and development of a geological model at Promontorio.

Minaurum has drilled 7 holes at Europa-Guadalupe, 2 at Alessandra, 2 at San José, and 1 at Ana in 2021.  Assays are pending for the second hole at Alessandra and the San José holes. 

Table 1.  Assay highlights, holes AL21-080, -081, -082, -083, and -084, -085, -086, -087, and -088.  Locations of holes are shown in Figures 2 and 4.  AL21-081 was drilled at the Ana zone, AL21-085 at Alessandra, and the rest drilled at Europa-Guadalupe.

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.
