Galp drops plans to build Aurora lithium refinery in Portugal
Galp was left alone in early 2024, when Northvolt said it would not invest in the 50-50 joint venture set up in November 2021.
Russia’s Alrosa (MCX:ALRS), the world’s top diamond producer by output in carats, said Wednesday it has found two large rough diamonds this week at its operations in Yakutia, in the country’s far East.
On Wednesday, a very large rough diamond weighing almost 110 carats was found at the company’s’ Mirny Mining and Processing Division. Two days earlier, a 75-carat rough diamond was recovered at the Processing Plant No. 14 of Aikhal mining and processing division.
Alrosa believes both rocks are gem-quality, but will confirm that once the diamonds are analyzed at the company’s diamond sorting centre.
Both rocks, said the Russian miner, are octahedron crystals with small inclusions, one of them with a straw-yellow tint. Following the company’s tradition, they will be given a name in the coming days.

Alrosa “believes” they are gem quality, meaning they are not D/E/F/G color, small inclusions meaning they may not be IF/VVS/VS clarity. Going by conventional wisdom the 110 carat raw stone may turn into 25 carat max diamond of G or lower color, VS or SI clarity. The 75 carat raw stone into a 15-20 carat diamond of same quality. Combined, both may be worth a quarter million max. This is minute compared to the billions they make out of millions of carats small stones. These stones are only good for once in a while media exposure for Russian, Canadian diamonds.
I believe quality diamonds come from Africa and sometimes from Australia.
