Mantaro Precious Metals (TSXV:MNTR) has announced results from the down dip extension of five historically mined veins at its La Escarcha project, and that it has completed the first four drill holes at its Golden Hill Property. 

As part of the maiden 5,000-metre drill program at the La Escarcha deposits, Mantaro has drilled 720 metres. The news of the completion of the first four diamond drill holes also came with the confirmation of down dip extensions, intercepted from the five primary gold-bearing quartz shear zones exploited via surface open and underground workings at the mine. This work was historically completed to depths of 150 metres beneath surface.

Craig Hairfield, Chief Executive Officer of Mantaro Precious Metals, commented in a press release: “We are extremely pleased with the progress made by our team and Leduc Drilling at La Escarcha.  Core recovery has been excellent. The four holes drilled to date have all intercepted sulphidic quartz-carbonate veins and veinlets beneath mineralization mapped in underground workings. Mineralization is open in all directions and the next phase of drilling will initially target the southern and northern strike extensions of the system. The system remains open at depth. It is anticipated that the first batch of samples will be dispatched to ALS this week and assays are expected approximately 6 weeks after.”

Highlights from the results are as follows:

  • Four diamond drill holes completed for a total of 720 meters, confirming down dip extensions of the La Escarcha gold deposit (See Figure 1).
  • Initial drilling has successfully intercepted down dip extensions of the five primary gold bearing quartz shear zones historically exploited via surface open pit and underground workings at La Escarcha Mine, to depths of 150 meters beneath surface.

The initial holes are targeting down dip extensions of historically mined veins at La Escarcha open pit, aiming to confirm high-grade gold mineralization beneath the extent of historic mining (ie. below 60 meter depth).  Drilling has successfully intercepted broad multiphase quartz shear zones typical of greenstone hosted orogenic gold deposits.  The program has also confirmed down dip extensions of the historically mined C1, C2, C3, C and C4 gold bearing quartz shear zones at La Escarcha gold deposit, to depths of 150 meters beneath surface.

The vast majority of the diamond drilling was drilled in PQ diameter and reduced to NQ size at 150 meters depth in hole GH0003.  Holes have been drilled from -34 ° to -61 ° dip, with hole lengths ranging from 170 to 250 meters, and an excellent core recovery of nearly 100%.

Additional drilling aims to further extend the down dip and strike extensions of the five key gold bearing structures at La Escarcha gold deposit.  Thereafter, the drill programs focus will shift to the southern strike extensions of the Golden Hill vein system, beneath areas with historic surface workings, at the Gabby and Garrapatillia prospects. Drilling will then be utilized to test gold mineralization across the parallel vein swarm located directly west of La Escarcha at the Westfield prospect.
