Element 25 is up over 800% since its March lows, buoyed by Teslas announcement of moving its battery technologies to a new innovative type of lithium-ion battery with a cathode that contains around 33% manganese, made directly from manganese metal. Could be worth a look - especially being a "green" producer of Manganese.
From their website:
Element 25’s wholly owned Butcherbird Project hosts a very large manganese resource containing over 260 million tonnes of resources. This world class resource underpins the Company’s core strategy of entering the manganese market with a low capital cost manganese concentrate export start up operation following by a downstream processing pathway to produce high purity manganese products powered with renewable energy. A cleaner, lower carbon flowsheet coupled with high penetration renewable energy place Butcherbird at the forefront of sustainable metal production.
