Firstbrook is a 100%-held mineral-claim block in Firstbrook Township promoted for natural geologic hydrogen. Protium initially staked 51 claims in September 2024, added 52 in October and announced another 24 in December, describing more than 2,600 hectares in total; its latest annual filing conservatively describes 103 claims over more than 2,100 hectares. Satellite surveys outlined persistent hydrogen-related spectral targets, but these are remote-sensing indications rather than surface samples, drilling or a discovered resource. Natural hydrogen is not available in the commodity schema, so commodity fields remain null.
