(AZT: TSX-V, OTCQB:AZZTF) reports high goldrecoveries by cyanide leach analysis of five (5) drill holes from the Californiaporphyry gold-copper prospect on the Cervantes property in Sonora, Mexico. Thedrill holes were selected from a northeast to southwest fence to represent thefollowing main types of mineralization: oxide, mixed oxide-sulphide, copperenriched, and sulphide. Excellent gold recoveries by cyanide leachanalysis include 87% gold and 45% silver recovery over 98.0 meters in hole18CER007, 84% gold and 54% silver over 106.0 meters in 18CER006, and 84% goldand 49% silver over 93.5 meters in hole 17CER003.Silver recoveries around 50% are considerednormal for most oxide gold deposits, as silver has slower leach kineticscompared to gold.\"We are very happy to see such high goldrecoveries using the ALS-Chemex cyanide leach analysis, a clear indication thatthe precious metals in the gold oxide cap of this newly discovered porphyrygold-copper system are amenable to leach processing\", commented Joey Wilkins,President and CEO.\"We plan to conductmore detailed metallurgical test-work on both leach and flotation recoveries inorder to more fully un-lock the mineral potential of the California zone butthese positive leach results are a great start.\"Table 1: Cyanide leach results, holes 17CER003,18CER006, 18CER010, & 18CER015 Drill Hole Interval(m)From(m)To(m)Au Rec(%)Au(gpt)Ag Rec(%)Ag(gpt)MineralizationType17CER00393.50.093.584%0.7249%3.0Oxide17CER00325.593.5119.051%0.2457%1.2Mixed 18CER006106.00.0106.084%0.3654%1.9Oxide 18CER00798.00.098.087%0.7045%1.7Oxide 18CER01042.00.042.075%0.7255%3.8Oxide18CER01054.042.096.019%1.0517%3.8Cu Enriched18CER01040.096.0136.073%0.1224%2.4Mixed18CER01029.0136.0165.033%1.1019%3.3Sulphide 18CER01542.00.042.070%0.5468%3.3Oxide18CER01529.042.071.022%0.4030%0.9Cu Enriched18CER01516.071.087.052%0.4149%0.4SulphideNote: Au gpt and Ag gpt grades are original weighted average assays fromBureau Veritas In addition to excellent gold recoveries from oxidematerial, significant cyanide leach r...
