Arizona Silver Exploration Inc (CVE:AZS, OTCQB:AZASF) has posted the results from seven holes, which make up the first quarter drilling program at its flagship Ramsey project in the US state.
One hole hit an intercept 51.83 m (meters) thick of 19.4 g/t (grams per ton) Ag (silver) at Ramsey.
All holes hit intervals of mineralization
Another highlight threw up 24.39m at 18.6 g/t silver.
The average assay over the seven holes was around 22 metres at 18 g/t silver, or 0.53 opt (ounces per ton).
All holes hit intervals of mineralization within a package of altered rhyolite and quartz latite, which were peripheral to higher grade mineralized intervals reported previously, Arizona said.
"The seventh hole was drilled at an angle to the northwest to test the potential northward strike extension to the Ramsey Mine silver system, and also appears to have intersected the low-grade margin of the higher-grade silver system," said Greg Hahn, the president and chief executive.
"These holes all appear to represent the true thickness of the mineral system at these locations."
Creosote vein update
The resource firm also updated on the creosote vein, which has yet to be drill tested and lies southeast of the Ramsey mine.
Surface sampling has shown elevated Ag-Pb-Zn-Ba - silver, lead, zinc, barium and the vein has had limited historic production of around 10 opt (ounces per ton) silver.
Sampling by Arizona Silver returned values of up to 877 gpt (grams per ton) silver in outcrops of what might be the extension to the Creosote Vein.
Meanwhile, a similar-sized area north of the Creosote vein contains a strong Ag-Pb-Zn-Ba surface anomaly, the firm added.
Ten further holes have been permitted and are tentatively planned for the second quarter of 2018 to test the areas featuring the surface geochemical anomalies, the group added.
