I hold shares in company to achieve SP gain from profitable operation of mining the discovered mineral
Below comparison of 2 minerals

• 
  The production costs of lithium and copper in December 2023 can be estimated as follows:

	Metal	Source	Production Cost (US$/kg)
1	Lithium	Brine	7.71
2	Lithium	Hard Rock	14.33
3	Copper	Average	4.52

• Market prices: Lithium prices have dropped significantly in the last 12 months, from $23.5 per kg in November 2022 to $14.5 per kg in December 2023, a decrease of 38.3%¹.This is due to low demand and high supply of lithium in China, the largest market for electric vehicles and batteries, increased production and competition from lithium miners in Australia, the largest producer of lithium raw material spodumene, and technological innovations that can reduce the cost and environmental impact of lithium extraction and processing²³. Copper prices, on the other hand, have risen slightly from $9,500 per tonne in October 2022 to $9,800 per tonne in December 2023, an increase of 3.2%.This is due to the ongoing Russia-Ukraine war, which has disrupted the supply of energy commodities and increased the demand for copper as a substitute, as well as the continued growth of the renewable energy and electric vehicle sectors, which require large amounts of copper³.

Seems hard rock lithium hardly profitable
