PHASE I & PHASE II DRILLING

 

​

IMP due diligence exploration involved drilling 52 boreholes at locations with proven deposits based on outcrops and drilling (plus an existing mining pit) that have generated 25 intercepts with Lead and Zinc ore veins.  Drilling locations include (see diagram to right) 27 Phase I holes in three vein zones identified as the NORTHERN AREA, THE MIDDLE AREA and the SOUTHERN AREA, and 25 Phase II holes identified as SITE A and SITE B.  See a overview of drilling locations to the right.​  While this exploration is only to prove the existence of the deposit, it infers a significant resource.

​

IMP geologists have recently identified what is believed to be a vein running from the northeast to southwest connecting the various veins with the anomaly, which area crosses where the unlicensed mining occurred.  The adjacent maps do not include this vein, and reserve estimates do not include any resource estimates deriving from it as it has not been verified along its run.

ROUGH RESOURCE ESTIMATE

​

IMP MINERALS’ geologist has done preliminary drilling for 5% of the identified 15 km of vein in the concession, with 5 veins having been drilled to confirm the existence of a significant Lead and Zinc deposit.  Assuming these veins extend to an average vein depth of 100 meters and approximately 1 km in length, AIMS expects that the veins will be proven to contain a resource in the range of 10 million metric tons of Ore with an estimated average metal content of 15% to 30%.  

​

An average assay based analysis of quality has not been conducted such that indicative assays are used to represent metal content, suggesting an inferred resource of perhaps 10 million metric tons based on a 4.5 specific gravity.

 

In addition to the 5 km described, another 10 km of potential vein zones, more or less, have been identified by the Ground Magnetic Survey and by mapping outcrops, which zones have not been drilled or proven even to be Lead and Zinc metal veins, and which are not included in our general resource estimate.

 

AIMS has recommended that once permits and licenses allow, a JORC-compliant exploration program of the 5 km of veins that have already been proven to exist with drilling intercepts, be conducted, which is IMP's current plan.
