2 ASX All Ords shares smashing multi-year highs
Silex Systems Ltd (ASX: SLX)
The share price of Aussie tech company Silex Systems hit a nine-year high on Wednesday, leaping to $3.36 in intraday trade.
That represents a 12% gain and came on the back of news of a milestone for the company's Zero-Spin Silicon project.
A stage 3 demonstration plant has been constructed to verify the commercial production capability for the quantum computing material.
The production technology for the silicon is based on a variant of the company's Silex laser isotope separation platform technology.
Silex Solutions expects to begin selling small amounts of Zero-Spin Silicon next year.
Whitehaven Coal Ltd (ASX: WHC)
It might not come as any surprise, then, that coal prices lifted once more overnight. Thermal coal futures rose 0.9% to reach US$399.65 in Tuesday trade.
The Whitehaven Coal share price has been on a tear in 2022, gaining 130% year to date. Meanwhile, the black rock's value has surged amid sanctions on Russian commodities resulting from the nation's invasion of Ukraine.
The ASX All Ords coal producer announced earlier this week it expects to report $3 billion of earnings for financial year 2022. For comparison, the company brought in $200 million in earnings last financial year.
