#Copper is omnipresent nowadays, but I came around to liking #molybdenite more, so my vote goes to the dark horse of the race.

#Copper has been holding on to an 8% lead most of the match. It’s a lot, but #Molybdenite could catch up.
What topics should we cover in the #OreCup victory post?

#OreCup finals are between a pair of bewitching ore minerals that glitter and gleam. But only one can have your vote.
Will it be native copper or molybdenite? You’re running out of time to choose!

correction from earlier post (about semi final 2 still!), it's native copper vs molybdenite in the final! easier one for me, much as I love copper minerals I'll go with the soft sulfide!
We’re in the final stretch of #OreCup!
Native #Copper is an ore so integral to our history that we named several eras after it and its alloys
#Molybdenite spent centuries tricking us into thinking it was something else entirely

Not sure about ores or minerals but TIL about the word "vug". It's such a weird little word with such an interesting story
(the image on the left, with the copper, apparently depicts a vug, not to be confused with a wug which is not depicted on either of the images)
