Vancouver, BC (FSCwire) - Aztec Minerals Corp. (AZT: TSX-V, OTCQB: AZZTF) has intersected long intervals of porphyry gold (copper, silver) mineralization including shorter intervals of high grade gold mineralization in the initial results of its Phase 1, 15 hole, 3,000 metre (m) drill program at the Cervantes Project in Sonora State, Mexico.
Drilling Highlights Include:
- 139.0 m from surface grading 0.71 grams per tonne (gpt) Au, including 2.10 gpt Au over 20.0 m and 2.0m of 5.52 gpt Au in hole 17CER005 at the California zone
- 117.0 m from near surface grading 0.63 gpt Au, including 1.18 gpt Au over 43.0 m and 2.0m of 4.05 gpt Au, in hole 17CER003 at the California zone

Joey Wilkins, CEO of Aztec, commented: "These positive results from three of the first five drill holes of our Phase 1 drill program confirm that the California zone has excellent bulk tonnage porphyry gold (copper, silver) potential at Cervantes. Holes 3, 4 and 5 were drilled to test a small part of a large surface geochemical gold anomaly on the hill that forms the California zone.
“As expected, we intersected gold oxide mineralization where the copper has been partially leached out as well as mixed oxides-sulfides transitioning to sulfide mineralization at depth. The entire California zone is underlain by a large, strong IP chargeability anomaly from 100 m depth down to at least 500 m that could represent the heart of a porphyry gold (copper, silver) sulfide system.
“A total of 810 m were drilled in the first five holes, and we are currently drilling hole nine. Our first two drill holes intersected anomalous but sub-economic copper-gold-molybdenum oxide mineralization from top to bottom in the Jasper zone west of the California zone. The main focus of our remaining holes in the Phase 1 drill program will be to systematically test the western half of the much larger California zone.”
Brief hole-by-hole descriptions follow below.
17CER001: Jasper zone – to test high grade oxide copper-gold mineralization near a north-south fault
0-15.85m Overburden
15.85-42.5m Polymictic Breccia composed of hornfels sediments and quartz feldspar porphyry, hematite-goethite matrix filling. Hole was lost due to broken ground and fault gouge.
Assays range from trace up to 0.05 gpt gold, 0.09% copper, 6.10 gpt silver
17CER002: Jasper zone – 50 m north of Hole 1
0-7.0m Overburden
7.0-227.0m Polymictic Breccia, hematite to goethite matrix, disseminated and veinlet oxides, scattered minor copper oxides, moderate iron and manganese oxides, locally silicified fragments and matrix, minor chlorite, strong foliation and fracturing, also Quartz Feldspar Porphyry, Aplite Dike

Joey Wilkins, B.Sc., P.Geo., President and CEO of the Company, is the Qualified Person who reviewed and approved the technical disclosures in this news release. All core samples were split in half, placed into plastic bags, labeled with sample number, closed with zip ties, and placed in rice sacks. Samples were typically collected in 2.0m intervals with occasional exceptions of 1.5 or 3.0m intervals. Blanks, duplicates, and certified standards were inserted into the sample stream and subsequently reviewed without any outliers or abnormal results. The samples were delivered to Bureau Veritas Laboratories in Hermosillo and analyzed for gold using a 30gram sample by fire assay fusion with AAS finish. Samples were shipped to Vancouver and analyzed with a 0.25gram sample using 4-acid ICP-MS providing analysis on 45 elements.
The Cervantes Property is held under an option to purchase agreement with Kootenay Silver Inc. (TSX-V:KTN) whereby Aztec can acquire up to 100% interest in the property in two stages. Additional information can be found on our website.
