Five of seven sample lines confirmed the previous highly anomalous soil sample results and the extensive porphyry-type gold mineralisation intersected in the Phase 1 drill programme, the company reported.
Other significant results included 0.4gpt gold over 84m in Line C; 0.32gpt over 183m in Line D; and 0.53gpt over 81m in Line E.
Aztec highlighted Line G, which returned 0.02gpt gold over 111m as being of particular interest, next to drill hole 18CER017, which intersected 0.35gpt gold over 116m, including 62m at 0.5gpt.
"More studies are required to understand the controls on mineralisation and infill drilling should help to better define the geometry of the subsurface mineralised zones," the company said.
Its current C$182,000 Phase 2 exploration programme is focused on geological mapping, rock, soil and sediment sampling and airborne magnetic and radiometric surveys to better define more drill targets on the recently expanded 3,649ha Cervantes property.
To date, soil sampling results ranged from 0.005gpt gold up to 3.3gpt gold, but mostly between 0.05 to 1gpt gold and confirmed four historic prospects as highly anomalous gold targets.
These include soil assays up to 0.33gpt gold at the California north extension, which remains open to the north and west; Purisima East soil assays up to 3.3gpt gold, 15 samples of which reported more than 1gpt gold over a 700m by 700m anomaly; Purisima West soil assays up to 0.61gpt gold, which remains open to the east; and the Jacobo target soil assays of up to 0.66gpt gold, which remains open in all directions.
The California prospect remains a top drill priority to expand the known porphyry-type mineralisation. An airborne magnetic and radiometric survey is scheduled for completion in October, which should assist in identifying new drill targets and to refine the company's understanding of the deposit.
The Cervantes property is held under an earn-in option whereby Aztec can acquire up to 100% interest in the property in two stages. Upon completion of the earn-in, Kootenay Silver will retain a 2.5 % net smelter return royalty and receive a payment of US$5/oz of gold or gold equivalent, based on the establishment of a compliant resource estimate.
