Is it permissible to deal with a gold and silver mining company that offers shares online and pays a variable monthly percentage based on the daily price of the ounce?

Firstly: Working in the field of mining and extracting gold and silver, and trading in them, is permissible. There is no objection to purchasing shares in the company, but it must be confirmed that the company does not sell gold or silver on credit (deferred payment), because selling them for cash requires immediate possession (taqabud) at the time of the contract. If it becomes clear that the company sells on credit, then it is considered one of the mixed (forbidden) companies.

Secondly: The principle regarding profit distribution is that it should be linked to the proportion of capital contributed and the percentage of profits achieved by the company. There is no issue with the profit amount varying from month to month according to the price of gold, but the shareholder's percentage of the profit must be fixed in every contract and agreed upon in principle. It is preferable to send the text of the agreement for review to understand the nature of the contract.
