A three-hole reverse-circulation drilling program at the East Pilbara project intersected porphyry-related copper-molybdenum-tungsten mineralisation extending for more than a kilometre.

The mineralisation begins at surface and varies in intensity throughout the entire length of each 250m hole. It remains open in all directions.

Molybdenum intercepts peaked at 0.68%, with tungsten recorded as high at 0.38% and copper 0.42%.

Best assays include 29m at 0.22% copper and 0.03% tungsten from surface; and 32m at 0.07% molybdenum from 117m.

Platypus managing director Tom Dukovcic said the results were promising.

“The persistence of copper-molly-tungsten mineralisation to a depth of at least 250m and the presence of very high grades of molybdenum and tungsten make these very exciting results,” he said.

The drill sites were limited to creek beds and depressions in an effort to avoid the costs of extensive roadworks, meaning target anomalies are are yet to be optimally drilled.

The company said this left scope for even stronger results as exploration progresses.

“Each hole nevertheless returned excellent results for a first-pass program, confirming the large size of the mineralised area and, therefore, the real potential for a substantial source,” Dukovcic said.

“This source porphyry will be the focus of future work.”

Platypus is currently earning a 75% interest in Gobbos through a farm-in agreement with Gondwana Resources.

The company must spend $A500,000 on exploration in the first three years to reach 51% before spending a further $500,000 in the following three years. The agreement is in its second year.

The next phase of work is scheduled for around April or May after the wet season.

In the meantime, Platypus will turn its attention to its Peruvian zinc-lead-silver interests.

Shares in Platypus are currently up 12.5% to A1.8c.
