Polymetals Resources (ASX:POL) has completed its recently expanded drilling program at the Carpark prospect.
Carpark is located 150m to the south of the Endeavor Mine from which 32 million tonnes of ore has been mined to produce 91.8Moz of silver, 2.6Mt of zinc, and 1.6Mt of lead.
Since 15 February 2024, some 1,198m of reverse circulation drilling, 318m of oriented HQ core, and a 360m down hole electromagnetic survey (DHEM) has been completed. A total of 8 holes have now been drilled at the Carpark prospect since mid-December 2023.
Geological observations in combination with semi-quantitative multi-element data collection using a portable pXRF strongly indicate a buried sulphide source to the immediate south of the Endeavor Main Lode orebody.
Broad coherent zinc anomalism proximal to quartz-ankerite veins preferentially developed in the coarser sediments of the CSA lithology, are thought to represent an outer halo to a deeper sulphide source.
Secondary enrichment of zinc oxides in combination with pyrite-chlorite development on fractures and cleavage, are considered as additional evidence of a potential sulphide source south of the Endeavor Main Lode.
Zinc and Lead anomalism first identified in RC drill hole PCP0012 now extends for over 150m in an east west direction and over at least 100m along a 310° to 330° corridor. The company says this presents an immediate and compelling target proximal to existing underground infrastructure.
A subsequent DHEM survey of hole PCP008 has located a conductive plate some 50m north of the hole. The significant zinc anomalism and DHEM survey results from the recent drilling has further strengthened the prospectivity of the Carpark Prospect to potentially host a down dip primary sulphide source.
Work has commenced to design a further drill program to test the down dip potential of current drill intercepts via percussion and oriented core.
