A little-known ASX mining share is setting the bar high today.

In morning trade, the All Ordinaries Index (ASX: XAO) is up a healthy 0.38%.

But this mining stock is leaving those gains in the dust.

Any guesses?

If you said Rox Resources Ltd (ASX: RXL), give yourself a gold star.

Rox Resources entered a trading halt on Friday pending today's announcement.

The gold miner's shares closed Thursday trading for 14.5 cents each. This morning, the Rox Resources share price shot as high as 23.5 cents, up a whopping 62%. At the time of writing, it remains up an impressive 48% at 21.5 cents a share.

Here's what's driving investor interest in the ASX mining share today.

ASX mining share rockets on bonanza gold strike

The Rox Resources share price is off to the races after the company reported some very promising initial drilling results. Those come from the reverse circulation (RC) and diamond drilling (DD) programs at its Youanmi Gold Project, located in Western Australia.

The announcement was made in conjunction with its joint venture partner, Venus Metals Corp Ltd (ASX: VMC). The Venus Metals share price is up 11% on the news.

The ASX mining shares reported that the first of a series of holes at Youanmi returned continuous bonanza grades in RC drilling.

The release highlights results of 28 metres at 34.81grams of gold per tonne from 204 metres including:

• 18m @ 51.96g/t from 207m, including;
• 10m@ 79.55g/t from 211m, including;
• 3m @ 138.07g/t from 218m

The miner said the results open up a new near-mine area for exploration and potential high-grade resource growth. With the true widths currently unconstrained, follow-up drilling is planned to determine the orientation and dip direction of the discovery.

Commenting on the initial drill results sending the ASX mining share soaring today, Rox Resources managing director Robert Ryan said:

Youanmi South is just 250 metres from the Youanmi main open pit, yet historical drilling was largely restricted to the weathered zone so true geology has been unconstrained.

The exceptional grade and continuous high-grade tenor of the intersection in an area previously untested by drilling is cause for cautious optimism whilst we determine orientation of the mineralised zone.
