The S&P/ASX 200 Resources Index (ASX: XJR) is underperforming on Thursday, but these ASX mining shares are bucking the trend to record whopping gains.

They've all surged more than 20% today – some for no apparent reason.

Let's take a closer look at what's going on with these three ASX mining shares.

3 ASX mining shares rocketing higher

Galileo Mining Ltd (ASX: GAL)

The Galileo Mining share price is surging upwards once more on Thursday, gaining 49.2% to trade at $1.41.

Its gains come on the back of assay results released by the company this morning. The results from six drill holes have confirmed palladium, platinum, gold, copper, and nickel at the company's Norseman Project's Callisto discovery.

Galilea Mining is now planning to kick off another 20-hole drilling program at the discovery next week.

Its shares are now up 509% this year to date.

Resource Mining Corporation Limited (ASX: RMI)

The Resource Mining share price is also launching higher today. It's surged 33% to trade at 14 cents right now. That's a new multi-year high for the ASX mining share.

There's been no news from the Tanzania-focused nickel explorer since 17 May. However, it did release a non-price sensitive investor presentation on Thursday.

The company is continuing to work towards its acquisition of five nickel projects in Tanzania, as announced earlier this month.

Resource Mining shares have soared 350% since the start of the year.

Ragusa Minerals Ltd (ASX: RAS)  

The final ASX mining share to post a whopper of a gain on Thursday is Ragusa Minerals. The company's stock is currently 22.7% higher, trading at 14 cents.

There's been no news from the $14 million gold-turned-lithium explorer today.

However, it announced its spin towards the 'white gold' that is lithium earlier this week.

The company has shaken on a tenement farm-in agreement that will see it able to earn an initial 90% interest in five lithium prospective tenements in the Northern Territory. It also has the option to up its stake in the tenements to 100% in the future.

Since the start of 2022, the Ragusa Minerals share price has gained 69%.

The market has come to a close for the week and all (or at least most) seems well. That's especially true in the camps of these ASX mining shares.

Despite a spot of trouble through the week, the All Ordinaries Index (ASX: XAO) finished it 1% higher than it started. It was a similar story for the S&P/ASX 200 Index (ASX: XJO), which recorded a gain of 0.9% over this week.

It was a better outcome for these ASX mining shares. They each recorded gains of up to 20% on Friday. Let's take a look at what pushed them upwards.

3 ASX mining shares rocking the market on Friday

Chalice Mining Ltd (ASX: CHN)

First up is ASX 200 mining share, Chalice Mining. The mineral exploration company recorded a gain of 19.06% on Friday, closing the week at $6.81.

The company released good news about its Julimar Project today. The project is being explored for commodities including nickel, copper, platinum group elements, cobalt, and gold.

Excitingly, Chalice Mining today announced it has been granted approvals needed to start low-impact exploration drilling at the project's Hartog-Dampier targets. The drilling will test for green metals in the area.

Nico Resources Ltd (ASX: NC1)

Next up is the Nico Resources share price. The ASX mining share surged 11.06% today to close the week at $1.16.

Interestingly, there's been no news from the recently listed nickel explorer since late last month.

However, the price of nickel surged 8% on the London Metal Exchange overnight, rising to trade at around US$28,200 a tonne. That's the highest it's been since 10 May.

Resource Mining Corporation Limited (ASX: RMI)

The third ASX mining share recording a major gain on Friday is Resource Mining. It's share price soared 19.57% to close at 11 cents.

Market watchers will be forgiven for not instantly recognising Resource Mining. The company is focused on nickel exploration in Tanzania and has a market capitalisation of around $36 million.

Thus, it could also have gained on the back of higher commodity prices. Though, today's gains might also be related to a capital raise and debt repayment the company announced on Tuesday.
