The company completed a diamond tail of a hole which returned 172m at 1.68 grams per tonne gold and 0.21% copper in July.

The tail more than doubled the intersection to 362m at 1.4gpt gold and 0.16% copper from 230m, including a previously reported 78m at 2gpt gold and 0.28% copper and 47m at 2.82gpt gold and 0.22% copper.

The intersection included 0.4m at 70.5gpt gold, 1.01% copper and 13.45gpt silver from 554m.

Antipa managing director Roger Mason said the hole demonstrated the capacity of the intrusion-related breccia system to generate broad intersections and support a revised resource estimate.

Another hole returned 66m at 1.28gpt gold and 0.08% copper from 403m, including 2m at 22.17gpt gold, 1.25% copper and 6.85gpt silver.

Mineralisation has been intersected along 500m of strike, is 275m wide and at least 600m deep, and is open in several directions.

The Minyari and WACA deposits have a combined resource of 723,000 ounces of gold at 2gpt and 26,000t of copper at 0.24%.

Antipa has expanded its 2021 drilling program to target resource extensions and near-deposit greenfield targets.

Minyari Dome sits within 35km of Newcrest Mining's Telfer operation and 54km along strike from Newcrest and Greatland Gold's 3 million ounce Havieron deposit.

Antipa has a total of nine rigs drilling across its four projects, which also includes farm-ins and joint ventures with Rio Tinto, Newcrest Mining and IGO.

Shares in Antipa rose as high as 5.7c and last traded 14.9% higher at 5.4c.
