Haggard Land Co Section 4-12N-7W

We received a letter from Haggard Land company and Camino about leasing our rights. This is all pretty new to us.

Their offer is to lease our minerals at $1,000 per net acre at 1/5th royalty. We are believed to own 0.45 acre so our bonus payment would be $450 a long with royalties. Does this sound accurate or fair?

thanks
