Rocky Mountain Discovers Zinc at Gibellini Vanadium Project, Nevada

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Nov. 15, 2007) - Rocky Mountain Resources Corp. (TSX:RKY) is please to announce the discovery of low grade zinc within a vanadium resource identified by reverse circulation drill program at the Gibellini project located in Eureka County, Nevada. The zinc appears to be a disseminated sediment hosted style of mineralization.

The initial program was designed to drill three holes through the portions of the Gibellini vanadium resource to collect metallurgical samples. A resource estimate was completed on the Gibellini Resource for the Company in conformity of National Instrument 43-101 by Wakefield, T and Orbock, E. III, of AMEC of Sparks, Nevada and reported on April 18, 2007. The resource consisted of:

Gibellini Mineral Resource at 0.1 V2O5 (%) Cutoff Grade and $5.50 V2O5
Price (April 9, 2007)

Tons V2O5 (%)
Indicated 20,796,348 0.338
Inferred 872,490 0.277

Assays of the new holes identified large blanket of low grade disseminated zinc within the vanadium deposit. A fourth hole (GIV-4) was drilled to test the southeast margin of the resource, which appeared to be open for expansion. The locations of the holes with respect to the resource are shown on the map below. The zinc may be significant if it can be recovered by sulfuric acid heap leach techniques. Vanadium is a metal used in the fabrication of high quality steel and currently sells for over $7 per pound. The number of pounds per ton of ore can be calculated by multiplying percent of by 20 (% X 20 equals pounds per ton).

The results of the holes are summarized using a 0.1% vanadium pentoxide (V2O5) and 0.1% zinc cut-off. The resource was explored by several companies in the 1960's through the 1980's. The Gibellini deposit is hosted in 150 to 300 foot thick Devonian shale enriched with vanadium. The Company is testing the resource for application of low cost open pit heap leach mining and processing techniques that might lower operating costs. The Gibellini deposit is unique in that most of the deposit lies on a hill with little waste rock. Additional testing will be required to determine if the zinc will be recoverable using heap leach methods. These drill holes indicate thicker intervals and lower total vanadium values (average 16% lower) than the nearby older holes. A drilling program using diamond drill core is currently in progress at the Gibellini project. This program will collect geotechnical data and conduct metallurgical testing to evaluate these differences and develop processing techniques.
