Description and Location of the Bruner Property

The property is located approximately 130 miles east-southeast of Reno, Nevada at the northern end of the Paradise Range and 45 miles northwest of the Round Mountain Mine. The Company has increased its holdings from 22 claims to 56 claims, which brings the total unpatented claims held to approximately 900 acres. Patriot now controls the entire Bruner Mining District.

Exploration History of the Bruner Property

The original operators at the Bruner Property are unknown. Prospecting at the property began in the early 1900's while mining was occurring on other properties located to the west. However, modern exploration of the property began in 1983 and included the following work:

  • In 1983, Kennecott Minerals Company drilled fifteen RC holes (holes left after the process of reverse circulation drilling) on the property.
  • In 1988-1990, Newmont Exploration Ltd. drilled approximately 10 RC holes; conducted detailed geologic mapping, geochemical surveys, air and ground magnetic surveys, and ground radiometric surveys.
  • In 1990-1995, Miramar Mining Corp. drilled 5 RC holes and conducted BLEG (bulk leach extractable gold) sampling and air photo interpretation. BLEG sampling involves a large sample of soil or rock that is leached using cyanide to determine gold and silver content down to a detection limit of as little as 1.0 part per billion.

Geology of the Bruner Property Mineral Claims

The Bruner mining district is underlain by a sequence of intermediate to felsic Tertiary volcanic rocks. A volcanic center, the origin of major volcanic activity, is thought to underlay the district. The exposed stratigraphic section measures over 2,500 feet in thickness. The "Duluth Tuff", a variably crystal rich ash flow tuff, is the host for gold and silver mineralization. Two generations of intrusive rocks have been described within the district. Ore in the Bruner district is hosted by vuggy, fractured, quartz-adularia (potassium-rich alternation mineral) -veined and/or stockworked tuff. Mineralization is primarily fault controlled, although some disseminated values do occur.

Geological Exploration Program

In 2003 and 2004, the Company completed an exploration program consisting of geologic mapping, surface geochemical sampling, and a ground magnetics and CSMT geophysical surveys to help identify pediment covered faults that could host gold/silver mineralization.

Geologic mapping of rocks exposed in the western portion of Patriot's claims shows several small quartz bearing structures trending northwest and dipping steeply to the northeast. These small structures may indicate larger veins at depth.

Interpretation of the geophysical surveys shows numerous northwest and north-south trending magnetic lows associated with faults. Magnetic lows are an occurrence that may be indicative of a destruction of magnetic minerals by later hydrothermal (hot water) fluids that have come up along these faults. These hydrothermal fluids may in turn have carried and deposited precious metals such as gold and/or silver.

Patriot's surface exploration program to date at Bruner has included:

  • Geologic mapping (producing a plan map of the rock types, structure and alteration);
  • Rock chip geochemical sampling (sample of rock, analyzed to detect the presence of valuable metals or other metals which may accompany them (e.g., Arsenic may indicate the presence of gold);
  • A ground magnetic survey; and
  • A Controlled Source Magneto-telluric (CSMT) survey (recording variations in a generated electrical field using sophisticated survey methods).

In October 2004 a total of 18 drill sites were located to target both extensions of the gold intercepts in previous drilling and in geophysical anomalies found by a CSMT survey.

We began drilling on the Bruner property in December 2004. This drilling program was completed in March 2005, with a total of 3,200 feet of reverse circulation (RC) drilling in 7 holes. The depths of the holes ranged from 300 to 750 feet. We have received assays for all holes and the results were encouraging enough that additional drilling was conducted.

In April 2005 we conducted additional drill testing on the Bruner property, including both reverse circulation and core drilling. Three fences of drill holes with the fences spaced 400 feet apart were drilled along the apparent trend of the mineralization. This program was completed in the fall of 2005 with 11 holes totaling 4,205 feet being drilled.

In November 2007, the Company drilled three more holes at Bruner to test deeper targets within the gold-bearing tuffaceous host rocks. The holes were drilled using an RC drill rig and totaled 3,240 feet. The holes were spaced roughly 400 feet apart on a line running east-northeast. All holes were angled steeply to the north to cut projected, south-dipping shear zones. Drill hole B-18 and B-19 were drilled 1,000 feet deep and B-20 was drilled 1,240 feet deep. All three holes contained intermittent gold at various depths.

The Company's work in the Bruner District has established two primary targets. The first are high-grade gold/silver veins associated with ancient hot springs systems. These quartz-calcite-adularia rich veins are hosted by faults within brittle, non-permeable host rocks. At the Penelas Mine, located within Patriot's claim block, a vein averaging 0.56 oz/ton gold was mined during the 1930's.

The second target is a bulk minable heap leachable Round Mountain type target. Both Patriot's drilling as well as the historic work at Bruner indicates the presence of low-grade gold hosted in permeable tuffaceous rocks. Numerous drill holes contain 20 to +100 feet long intercepts of +0.01 oz/ton gold. The Round Mountain Mine has produced over 10 million ounces of gold from a large open-pit heap-leach operation. The mine has been economic for many years producing at very low grades. The current grade being mined is 0.018 oz/ton gold according to a recent Kinross Gold Corporation report. Both the Round Mountain Mine and Bruner project occur within large volcanic centers and have similar host rocks.

Patriot has reviewed an extensive database it has acquired for the Bruner District. Besides surface work, this database includes results for 154 drill holes from various exploration programs beginning in the late 1970's.

Patriot has optioned the project to Canamex Resource Corp., which has the right to earn up to 75% of the project. Results of their exploration have been impressive to date, please see our latest news releases for current information.
