TETHYAN Copper Co is drilling out its H4 resource at the Reko Diq copper-gold project in Pakistan as part of a bankable feasibility study begun last quarter and set to run over the next 12 months.

The company aims to reduce hole spacings to 100m or less at H4 by the end of November.

During the June quarter, thirty-four holes were drilled into and around the current H4 resource, with the best intersections to date including 42m grading 1.33% copper from 46m, 48m at 1.12% from 44m, and 102m at 0.92% copper from 78m.

H4 currently contains 93.5 million indicated tonnes grading 0.7% copper and 14.8Mt inferred at 0.6% copper.

Tethyan also anticipates a significant extension is likely for the H4 resource after intersecting mineralisation to the west. Six out of eight holes returned ore-grade mineralisation, with significant intersections so far being 44m grading 0.78% copper, 48m at 0.5%, and 19m at 0.53%.

In regional exploration during the quarter the company identified a broad geophysical anomaly 70km north-west of Reko Diq along with two previously announced anomalies 20km and 30km to the west of the project.

The areas, not previously explored by Tethyan, form part of the company's goal of finding a large high-grade supergene enriched ore body outside of the Reko Diq complex.

At the H35 porphyry complex located approximately 2km from H4, Tethyan made the significant intersections 51m grading 1.05 grams per tonne gold, 129m at 0.83gpt, and 27m at 1.00gpt.

According to the company, the complex shows strong continuity vertically and horizontally, with mineralisation extending the full lengths of the four holes drilled at H35 during the quarter.

At the H11, H27 and Parrah Koh porphyries, Tethyan has intersected extensive low-grade copper-gold mineralisation, after completing three initial holes.

Tethyan shares were off 0.5 cent to 35.5c during afternoon trade on the ASX.
