Argent Mineral Management

Maximizing Wealth from Mineral Assets

Argent Mineral Management (AMM) exists to help our clients protect their property while maximizing wealth from their mineral assets. We provide all-encompassing mineral management services, including the accounting and auditing of royalty payments. 

Formed in 2005 to serve clients with mineral interests, we have been very successful in helping landowners protect and maximize their oil and gas assets. Our diverse staff of 30+ employees has decades of experience in banking, forestry, landman services, and accounting. We currently manage approximately 3 million acres of mineral interests across 30 states, and to date we have recovered over $30 million in revenue for our clients. 

Because of our size and reach, AMM clients also gain an unseen advantage – strength in numbers. Our lease negotiations on behalf of our clients benefit from our vast network of client landowners, which allows us a broad range of property-related information and intelligence, as well as increased leverage in negotiating with regional exploration companies, adding significant strength to each and every landowner’s portfolio.

Learn more about AMM’s services on our Oil & Gas Management Services page.
