Just checked the ASX this week and some interesting moves happening in the australian mining stocks space. Resolution Minerals absolutely crushed it - up 54% after landing FAST-41 status for their Antimony Ridge project in Idaho. Basically the US government fast-tracked their permitting, which is huge for their antimony supply play to the defence industry. They went from AU$0.046 to AU$0.077 in one day when the news dropped.

OD6 Metals wasn't far behind with a 45% jump. They released first assay results from their Quinn fluorspar project in Nevada showing some serious grades - up to 53.2% calcium fluoride. Then they came back Thursday with channel samples hitting 40.8% calcium fluoride over 12 metres. Pretty solid confirmation of what they're sitting on.

Cauldron Energy popped 34.88% this week after getting added to a uranium ETF. Their Yanrey uranium project in WA has been attracting attention with all the nuclear energy buzz going around. The ETF inclusion should bring more institutional money their way.

Xstate Resources moved 31.82% higher - they're progressing with flow testing on their Diona gas discovery in Queensland. Two-week testing window was supposed to wrap up mid-April. And Pivotal Metals rounded out the top movers with 30.77% gains on metallurgical testwork progress at their Horden Lake copper project in Canada.

Worth keeping an eye on these australian mining stocks if you're tracking critical minerals and energy plays. The sector's definitely got some momentum right now.
