Culberson County-surface rights

Hi there!

Just came back from a surreal meeting with a land man fromTexas. He said he is in our neck of the woods (Northern California) to talk to clusters of surface owners on our block and making offers to buy it. He works for Antelope/Capitan Production. He has been pursuing us via mail/phone in the last few months but we were shocked to see him in our front door with cashier’s checks on hand! Please, please, anyone out there, kindly let me know if $700/ac is a reasonable offer for 9.24 acres in NE quarter of section 2, block 112, public school lands, Culberson County. He was a very soft spoken person but he did say that if this Craig somebody is done and over with this section, he will move on and pretty much we’ve missed out. He gave us 30 days to respond but he is only here for another day or two. Please, anyone, any information on this area is well appreciated. Thank you in advance!
