Minaurum Drills 43.50 m of 1.01 g/t Gold at Aurena Project, Mexico
Minaurum Gold Inc. ("Minaurum") announces the results of the second group of five drill holes in its ongoing first phase drill program targeting a 3000 m long by 1500 m wide surface gold geochemical anomaly on its 100% owned Aurena gold-skarn project in southern Mexico. (See News Releases dated October 19, 2010 and May 9, 2011). The holes were drilled as step-outs from the first five holes and two of the holes in this second group intercepted significant thicknesses of sulfide-bearing prograde skarn-altered rocks, starting close to the surface.

The best results came from Hole AURC-11-006 which, starting at 4.50 m, cut 43.50 m of 1.01 g/t Au, including 19.50 m of 1.64 g/t Au. The highest grade sample was 3.48 g/t Au. The hole was collared 90 m north of hole AURC-11-005 and drilled S20W at -45 degrees. Mineralization is sulfide-rich with no evidence of significant surface or oxide enrichment.
Hole AURC-11-007, collared at the same location as AURC-11-006 but drilled to the west-northwest at minus 45 degrees. It intersected two important mineralized zones: 6.00 m of 0.84 g/t Au, from 34.50 m to 40.50 m; and 23.80 m of 0.99 g/t Au, from 125.20 m to 149.00 m. The highest grade sample was 2.86 g/t Au. A 1.5m intersection from 24.00 m to 25.50 m returned 1,280 g/t Ag (37 oz/t Ag) and 0.48 g/t Au.
"Continuing to intersect gold mineralization at surface confirms the potential of this gold-skarn system," stated Darrell Rader, President and CEO of Minaurum. "We now have near-surface mineralization in three contiguous holes that appear to lie along the fringes of a potentially stronger part of this gold system. Gold mineralization remains potentially open to the west, northwest, north, and at depth, from these two reported holes. Our ongoing step-out drilling program is aggressively focused on tracking down its extent."

Anomalous, but not significant gold values, were encountered in holes AURC-11-008, AURC-11-009, and AURC-11-010. Hole AURC-11-008 was drilled from the same location as holes AURC-11-003 and AURC-11-004, but to the east-southeast at minus 45 degrees. It cut anomalous gold values at the surface and in hornfels before entering a thick section of unmineralized marble. Vertical hole AURC-11-009 and angle--hole AURC-11-010 were drilled from the same collar location about 300 m to the southeast of hole AURC-11-008. AURC-11-010 was drilled to the south-southwest to test an aeromagnetic anomaly and the contact of the granodiorite/diorite intrusive body. Anomalous gold was encountered in both holes in discrete zones within broad intercepts of sulfide-bearing hornfels and skarn.
Minaurum is an explorer focusing on gold-dominant metals deposits in Mexico. The Company is currently advancing a portfolio of projects including the Aurena gold-skarn project.

Quality Assurance/Quality Control: Preparation and assaying of drilling samples from Minaurum's Aurena 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 Guadalajara, Jalisco, Mexico. Pulps of the samples are prepared in Guadalajara, from where they are shipped to Vancouver for chemical analysis by ALS Minerals. Samples are analyzed for gold by fire assay and ICP/AES on a 50-gram charge. In addition, analyses are done for a 51-element suite using aqua regia digestion and ICP analysis.
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 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 Aurena project.
Forward Looking Statement: Some of the statements contained in this press release are forward-looking statements. Forward-looking statements are not historical facts and are subject to a number of risks and uncertainties beyond the Company's control, including, but not exclusively, statements regarding potential mineralization, exploration results, completion of work program and studies, and future plans and objectives of the Company. Resource exploration, development and operations are highly speculative, characterized by a number of significant risks, which even a combination of careful evaluation, experience and knowledge may not eliminate, including, among other things, unprofitable efforts resulting not only from the failure to discover mineral resources but from finding mineral deposits which, though present, are insufficient in quantity and quality to return a profit from production.
