This is one county, not this owner’s holdings. The site holds mineral rolls for 114 of 254 Texas counties, so JAMCO ENERGY LLC may hold interests elsewhere that this page cannot show. Absence is not evidence.
The ground
The Original Land Survey abstracts this owner holds an interest in, on the Commission’s own survey grid. Click any outline to open that abstract.
64 of 76 interests are on the map, across 21 abstracts. An interest is placed only where the district’s legal description names an abstract this site can resolve. The rest are listed below without a location — that is a limit of the description, never a claim that the property is outside the survey grid.
