MINAURUM SAMPLES 102 G/T GOLD AND 4.6% COPPER AT NEWLY DISCOVERED ALESSANDRA VEIN
Minaurum Gold Inc. has made its first high-grade gold discovery at the Alamos silver project in Mexico. The newly discovered Alessandra vein zone lies in the eastern part of the project, approximately one kilometre southeast of the Ana zone (see news release dated June 5, 2018).Alessandra measures more than four metres wide in surface exposures, and can be traced for 1.1 kilometres, with a topographic linear suggesting it extends at least another one km to the southwest.
"The discovery of bonanza gold grades for the first time at the Alamos project corroborates the numerous mentions of high-grade gold in historical reports," stated Darrell Rader, president and chief executive officer of Minaurum. "The Alessandra vein system adds an exciting new facet to the district scale of the project and we look forward to testing it in our ongoing drill program."
The Alessandra vein zone is a one to four m wide, east-dipping vein zone hosted in faulted lower Cretaceous limestone. It has been traced in surface exposures for 1.1 km along strike and pronounced topographic linears suggest that the vein may continue for at least another km to the southwest.Copper oxides, epidote, quartz, specular hematite and manganese oxides dominate surface mineralization exposures.Chalcopyrite has been found in unoxidized hand specimens.Six samples assayed more than 100 parts per billion gold, including the 102-gram-per-tonne sample, which is the highest gold value recorded during Minaurum's two-year tenure on the property.Sixteen rock samples from the Alessandra zone assayed more than 1 per cent Cu, with the highest value of 4.6 per cent Cu.Anomalous Zn values included a sample running 4.90 per cent Zn.Notably, silver grades are low. Overall, the skarn mineral assemblage and contained metals suggests a proximal, skarn-dominated mineralization style than the distal epithermal mineralization seen elsewhere on the project.The felsic pyroclastic rocks to the east of the Alessandra zone appear to lie discordantly on the limestone that hosts the Alessandra zone, suggesting that additional Alessandra-style structures may lie to the east under the volcanic cover.

About Minaurum Gold Inc.
Minaurum Gold is a Mexico-focused explorer concentrating on the high-grade Alamos silver project in southern Sonora state. With a property portfolio encompassing multiple additional district-scale projects, Minaurum is managed by one of the strongest technical and finance teams in Mexico.
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.
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 per cent less than two millimetres, splitting off 250 grams, and pulverizing the split to more than 85 per cent 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 four-acid digestion and ICP analysis. Samples with silver values greater than 100 grams per tonne; and copper, lead or zinc values greater than 10,000 parts per million (1 per cent) are reanalyzed using four-acid digestion and atomic absorption spectrometry (AAS).
Quality control samples are inserted in the sample stream every 20 samples and thus represent 5 per cent 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.
We seek Safe Harbor.
