Evolution Mining Ltd (ASX: EVN), Whitehaven Coal Ltd (ASX: WHC), and Santos Ltd (ASX: STO) shares are turning heads today.

Two of the big-name ASX shares are charging higher today, while one is trailing the 0.4% losses posted by the S&P/ASX 200 Index (ASX: XJO) as we head into the Wednesday lunch hour.

Here’s what’s catching investor interest.

Santos shares lift on growth outlook

Santos shares are jumping higher today.

At the time of writing, shares in the ASX 200 oil and gas stock are trading for $8.37 apiece, up 3.2%.

This follows the release of Santos half year results (H1 2026).

On the positive side of the ledger, the company reported a 2% year-on-year boost in sales revenue to US$2.62 billion.

Production volumes were up as well, with sales volumes increasing by 1.7% to 48 million barrels of oil equivalent (mboe).

And investors appear to be eyeing the forecast future growth and shrugging off the 19% decline in Santos’ half-year statutory net profit after tax (NPAT), which fell to US$355 million.

As for that growth that could support Santos shares longer-term, the company revealed that Barossa has reached 97% of planned rates since the end of June. And in Alaska, the company’s Pikka Phase 1 project achieved first oil. Management expects the project to hit plateau production in the third quarter of 2026.

Santos CEO Kevin Gallagher noted:

The first half marked an important step forward for Santos. We brought the Pikka project online safely and continued to progress Barossa through commissioning towards steady-state production, while the base business continued to perform strongly.

Whitehaven Coal shares slide on revenue decline

Unlike Santos shares, Whitehaven shares are slipping following the release of the ASX 200 coal stock’s full-year FY 2026 results.

At time of writing, the Whitehaven share price is down 1.8% at $7.62.

For the 12 months the company reported revenue of $5.40 billion, down 7% from FY 2025.

And underlying earnings before interest, taxes, depreciation and amortisation (EBITDA) of $1.25 billion were down 8%.

On the bottom line, Whitehaven’s full year NPAT declined by 29% to $227 million, impacted in part by lower coal prices.

Still, management declared a fully franked final dividend of 6 cents per share, in line with last year’s payout.

Which brings us to…

Evolution Mining shares jump on record profits

Joining Whitehaven and Santos shares in making waves today, we find ASX 200 gold stock Evolution Mining.

Evolution Mining shares are up 1.1% at time of writing, changing hands for $13.80 apiece.

Investors are bidding up the gold stock following the release of Evolution’s own FY 2026 results.

Amid a rising gold price environment and its own operational successes, the miner reported a 44% year-on-year increase in underlying EBITDA to $3.17 billion. And cash flow surged 76% to a record high of $1.39 billion.

Evolution Mining also achieved an all-time high statutory profit after tax of $1.48 billion, up 59% from FY 2025.

This saw management boost the final fully franked dividend to 21 cents per share, up 62% from last year’s payout.

Rio Tinto Ltd (ASX: RIO) has been one of the stronger performers in the mining sector over the past year.

After a run like that, it is reasonable to wonder whether much of the opportunity has already been captured.

So, would I still put $5,000 into Rio Tinto shares this week?

The valuation still looks reasonable

Rio Tinto shares are currently trading around $168.84.

According to CommSec, consensus earnings per share estimates stand at $12.07 in FY26 and $12.04 in FY27.

That puts the miner on a forward price-to-earnings multiple of around 14 times in both years.

I think that looks reasonable for a global mining company with substantial exposure to iron ore, aluminium and, increasingly, copper.

There is passive income to consider as well. CommSec expects fully franked dividends of $6.63 per share in FY26 and $6.62 in FY27, which would represent a forecast yield of roughly 3.9% at the current share price.

That gives investors something back while waiting for the longer-term growth story to develop.

Copper is where I get more excited

The copper side of Rio Tinto is becoming increasingly important to my investment case.

Demand for the metal should benefit from spending on electricity networks, renewable energy, electric vehicles, data centres and other infrastructure needed as the global economy becomes more electrified.

Rio Tinto already has major copper operations, and Oyu Tolgoi in Mongolia is giving it a meaningful source of production growth.

Copper production from Oyu Tolgoi increased by 31% to 198,000 tonnes during the first half of 2026 as the underground operation continued ramping up.

I think the longer-term opportunity is even more interesting. Rio Tinto expects Oyu Tolgoi to produce around 500,000 tonnes of copper per year on average between 2028 and 2036 from its open pit and underground operations. At that scale, it is expected to become one of the world’s largest copper mines.

That gives Rio Tinto a growth project already moving towards much higher production at a time when I expect copper to become increasingly valuable.

What would make me cautious?

Rio Tinto shares have risen by around 50% over the past 12 months, so expectations are certainly higher than they were a year ago.

Mining earnings can also change quickly when commodity prices move. Iron ore remains an important contributor, while a weaker copper price could reduce some of the excitement around the company’s expanding production.

The relatively flat consensus earnings forecasts for FY26 and FY27 are a reminder of that cyclicality.

But I think Rio Tinto is becoming a more interesting business for the years ahead. Its copper production is growing, Oyu Tolgoi still has a long ramp-up ahead, and the wider portfolio gives the company several major commodities to work with.

Foolish takeaway

I would invest $5,000 into Rio Tinto shares this week.

The strong share price performance over the past year has made the entry point less attractive than it once was, but I still think around 14 times forecast earnings represents good value.

More importantly, I like where the business could be heading over the next several years as copper becomes a larger part of the story.

For investors prepared to accept the ups and downs that come with mining shares, I think Rio Tinto remains a strong long-term buy.

PLS Group Ltd (ASX: PLS) shares are pushing higher today.

Shares in the S&P/ASX 200 Index (ASX: XJO) lithium stock– formerly known as Pilbara Minerals – closed yesterday trading for $4.93. In late morning trade on Wednesday, shares are swapping hands for $4.96 each, up 0.6%.

For some context, the ASX 200 is down 0.4% amid renewed concerns over the enduring conflict in the Middle East.

Today’s outperformance is par for the course for the Aussie lithium producer, with PLS shares up 117.7% since this time last year, smashing the 1.6% one-year gains posted by the benchmark index.

Some of that strong performance has been fuelled by the 79% increase in global spodumene (a lithium bearing ore) prices. Though the miner has hardly been sitting idle.

So, with PLS having turned $10,000 into $21,770 in the last 12 months, is the ASX lithium stock still a good buy today?

PLS shares: Buy, hold, or sell?

Dolphin Partners Financial Services’ Arthur Garipoli recently ran his slide rule over the lithium miner (courtesy of The Bull).

“This high-quality pure play lithium producer recently delivered a solid June quarter report in fiscal year 2026,” he said.

“Sales were up 28% compared to the March quarter and group revenue was up 31%,” Garipoli noted.

PLS released those results on 30 July, with shares closing up 2.7% on the day. The revenue boost Garipoli mentioned saw the company report $743 million in revenue for the three months, with sales volumes of 249,900 tonnes.

While Garipoli sounded a positive note on the miner, including renewed dividend potential, he issued a hold recommendation on PLS shares for now.

According to Garipoli:

The company has benefited from rising spodumene prices and sustains a solid balance sheet. Restarting the Ngungaju processing plant is expected to materially lift sales into full year 2027. Speculation exists that PLS may resume paying dividends following stronger than expected cash generation in full year 2026.

In 2023, PLS paid two fully-franked dividends, totalling 25 cents per share. Those passive income payouts were suspended in 2024 amid slumping lithium prices.

What’s ahead for the ASX 200 lithium stock?

Looking to what could impact PLS shares in the months ahead, the company provided FY 2027 spodumene production guidance in the range of 1.03 million to 1.10 million tonnes, with growth spurred by the ramp up at the miner’s Ngungaju plant.

Costs are also expected to rise, with PLS forecasting FY 2027 unit operating costs (FOB) between $575 to $625 per tonne.

PLS also plans to increase its investment spend, forecasting full-year capital expenditure between $620 million to $685 million.
