New mineral alert! My first new mineral, wildcatite, is officially published - a calcium iron tellurate hydroxide, CaFeTeO5(OH). It is named for the small gold prospect in which it was found, Wildcat prospect in Utah, USA, which I visited in 2018.

#OreCup R2M2: It's slippery and silvery #Molybdenite vs peacock rock #Bornite! Are you supporting the only molybdenum (and rhenium) ore, or the hefty copper sulphide?

Huge dragon-shaped aggregate of native #Copper crystals from Ajo Mine, Pima Co., Arizona, USA.

Not copper metal like in #OreCup today, but (poorly managed) copper mining in general can leave to blue-green precipitates along waterways - and play host to some amazing Cu-tolerant plants!

Some giant clusters of very copper tolerant Nepenthes fusca seen here.

Congratulations, #Copper, and welcome to the #OreCup semi-finals.

Condolences, #Galena, we know this is a heavy loss.

[Stuart Batten @SBattenResearch]

Here's me getting my PhD with my supervisors - Bernard Hoskins and newly minted #NobelPrize Laureate Richard Robson. So thrilled for Richard, and thinking also of Bernard tonight (who passed away many years ago but was a crucial part of the story). #ozchem #ChemTwitter

One of the original contenders finally salutes in 2025! Tugtupite couldn't quite do a quetzalcoatlite. Already looking forward to next year!

[Mineral Cup #MinCup @MineralCup]

We have our #MinCup25 champion!!

Congratulations, #Kyanite!

After eight years of competing, another few hours to verify votes was nothing, right?

Amazing first run, #Tugtupite, and better luck next year.

Cuprosklodowskite for me, for its extra dose of vibrancy and interesting geochemistry!

Voting for tugtupite today!
too many perovskite votes aren't for the mineral but for the eponymous group of structures.
Tugtupite is also a beryllium containing mineral, and I do love a mineralogical oddity!
