Help Establish Weld County Mineral rights Value per Acre

My senior mom and her sister are being aggressively pursued by someone trying to buy the mineral rights they own for acerage in Weld County. I am trying to determine what price per acre they should be asking so they don’t get taken by someone who is trying to close very quickly.

The property description is: Township 7 North Range 65 west, 6th P.M. Section 02

S/W 1/4 lying south of the larimer and weld irrigation company ditch.

If you can help it would very much appreciated. Thank you.

Unfortunately there is no real activity going on in section 2 to create a high valuation for your minerals there. If you owned directly south in section 14, fair market value would be @ $6000 per net mineral acre.
