A K-aggregates occurrence/pit operation located in the E½ T21N, R102W, and into western T21N, R101W, 6th PM.

Mineralization is a 0.95 Ma old volcanic deposit with cinder cones and lava flows of diopside-sanidine-phlogopite lamproite (orendite). Vugs in some of the flows are filled with microcrystals of potassic-jeanlouisite, priderite, and apatite-(CaF).

Zirkel Mesa is the largest in the region. Complex flows appear to have issued from several conduits. The lavas rest on rocks of "Montana" age which have been cut by at least three faults; therefore the flows are later than the faulting. There are four cones of fragmental pumice on the mesa and one of consolidated lava. The mesa covers 3,300 acres, and the lava has an average thickness of 75 feet. The rock in the nearly horizontal part of the mesa has indicated and inferred reserves of 940,005,000 tons of leucite rock, or 94,000,500 tons of K2O. Irregularities such as cones, protuberances, etc. contain 1202,336,276 tons of rock, or 10,233,627 tons of K2O.


Part of the mesa is actually quarried for road gravel, and it is listed as a potassium deposit by the WGS.
