THE DRILL SERGEANT: Azure Minerals (ASX: AZS) reported results from a recent close-spaced soil sampling program undertaken across the company’s Sara Alicia property in Mexico.
Azure Minerals said the program identified areas of strong gold, cobalt and zinc anomalism.
Additionally, a ground magnetic survey defined a highly magnetic zone, which the company interpreted to represent the skarn body hosting the high-grade gold and cobalt mineralisation.
Soil samples were collected on a 25m by 50m grid spacing, defining a discrete zone strongly anomalous in gold and cobalt, with highest values of 1.26 grams per tonne gold and 1,469ppm cobalt (0.15 per cent cobalt).
The company highlighted these as being both very high values for soil samples.
The anomalies for both elements are coincident, are approximately 200m long and 100m wide, and align along the eastern flank of a well-defined northwest-southeast trending structural zone.
The western flank also hosts a very high-grade zinc-in-soil anomaly in the southwestern quadrant of the project area.
All 26 samples taken from within the 200m by 100m anomalous area returned assays exceeding 1,000ppm zinc (>0.1 per cent zinc) up to a maximum value of 35,400ppm zinc (3.54% Zn), with an overall average zinc grade of 0.45 per cent zinc.
“This very strong zinc anomaly is hosted in a different geological setting from the gold and cobalt mineralised skarn, providing Azure with another target horizon to follow-up,” Azure Minerals said in its ASX announcement.
Azure claimed the results of the ground magnetic survey and magnetic susceptibility measurements of the drill core from its first drilling program confirmed the close spatial association of the magnetic skarn body with high-grade gold and cobalt mineralisation.
“The surface dimensions of the magnetic anomaly are similar in area to the gold and cobalt anomalies identified by the soil sampling,” Azure said.
“Encouragingly, modelling of the data indicates that the magnetic body which represents the mineralisation has considerable depth extent, particularly to the north and northeast where it dips beneath an overlying limestone horizon, providing excellent targets to extend the gold and cobalt mineralisation in those directions.”
Azure indicated it is currently designing a drilling program to follow-up these positive results by testing for along-strike and down-dip extensions and the depth potential of the high-grade gold and cobalt mineralisation.
