Boss Project

The Boss project covers approximately 25.12 sq km (8,500 ACRES) and the Crystal Pass project covers over 7.77 sq km (1,920 ACRES), located in the Goodsprings Mining District 60 km west of Las Vegas. Boss, as well as the recently acquired Crystal Pass and Columbia Pass projects are all areas located in the Goodsprings District and owned 100% by Boxxer Gold.

The Goodsprings District was mined between 1886 and 1931.  The historical mining on the property is very similar to other porphyry districts worldwide, and specifically in copper-porphyry districts in Western USA.  Goodsprings has recorded historical production at 280 million pounds of lead and zinc at a combined grade of 26%, 2.7 million pounds of copper at an average grade of 13% and 65,000 ounces of gold at an average grade of one ounce per ton, resulting in the second largest mineral producing district in the Western USA at that time.

Goodsprings Mining District:
The Goodsprings Mining District is located at the interpreted intersection of the northwest trending La Caridad-Mineral Park Belt and the southwest trending Frontal Thrust Belt, both of which host very large porphyry copper deposits such as Butte in Montana and Bingham Canyon in Utah.

The Goodsprings Mining District exhibits all the typical signatures indicating a porphyry copper district, including the mineral zonation, styles of mineralization, copper sulphide minerals, alteration, geochemical signature and skarn development. The Goodsprings District exhibits an exceptionally large copper zone which typically occurs in the center of a porphyry district surrounded by base metal (lead-zinc) mineralization on the outside of the zone.  

Copper mineralization in the form of chalcopyrite, bornite and chalcocite as well as malachite, azurite, tenorite and cuprite occurs as disseminations, fracture and veinlet fillings and in breccia zones. 
Using recent mapping, sampling, and the results from airborne geophysical survey, Boxxer believes that  regional scale faults are the major controls over the location of the copper mineralization and intrusive activity within the District. 

Boxxer is using the mineralized skarn and geophysical data to guide its exploration for porphyry copper style mineralization in the Goodsprings Mining District. The exploration model being used is similar to the porphyry copper-gold deposits that occur at Butte in Montana and at Bingham Canyon in Utah.

Exploration to date on the Boss, Crystal Pass and Columbia Pass has identified an intrusive suite of rock that is typical of hosting porphyry copper style mineralization, two very large area of mineralized skarn development, areas of conductivity, and large Induced Potential/Resistivity and corresponding Magnetotelluric anomalies. Two areas of mineralized skarn occur on the Boss property.  The Boss Extension skarn hosts a total of 22 large yet undefined zones of copper-gold-silver mineralization, with significant concentrations of platinum and palladium.  The strike length is approximately 2,400 m with a width of 1,500 m  (results are summarized below).  The Copperside skarn, located approximately 1,000 m north of the Boss Extension, has a strike length of 1,500 m, a width of 900 m and hosts three large yet undefined zones of copper-gold silver mineralization. 

The exploration target Boxxer is using for the Boss and Crystal Pass projects expressed in a range of tonnes and grades that possibly could occur  is between 500 and 800 million tonnes grading between 0.7 and 1.0 % copper and between 0.20 AND 0.40 G/T gold. 

The potential quantities and grades for the exploration target on the Boss Project are conceptual in nature.  There has been insufficient exploration to define a resource and it is uncertain if future exploration will result in the target being delineated as a mineral resource. The basis for the potential quantities and grade are the historical and the 2005 to 2010 sampling results, the horizontal and vertical dimensions of the 22 mineralized zones, the dimensions of the mineralized skarn, the weighted average grade of the channel samples, the dimensions of the airborne geophysical anomalies and the dimensions of the recently TITAN-24 DCIP/MT targets.

The recently completed Quantec DCIP/MT survey has identified.  

• Boss Extension: 15 targets outlined;
• Crystal Pass: 17 targets outlined;

Boxxer’s President and CEO, Elmer B. Stewart, explained, “The results of the Quantec Survey are the single most significant set of data that has been generated from our Boss and Crystal Pass projects in the last 18 months.  The number of new targets has moved Boxxer a major step closer to proving the porphyry potential for this district.”

Boss Extension:
The Boss Extension is a large area of widespread mineralized skarn hosting 22 large (see table below) and yet undefined zones of copper-gold mineralization over an interpreted intrusive body. The locations of the targets identified by the Quantec Survey are shown in Figure 1 and Figure 2. Figure 1 shows the north-south oriented Induced Polarization (IP) section from the Boss area.

Numerous other smaller targets have been identified in the area of the Boss Extension that also warrant diamond drilling. 

Highlights from Surface and Adit Sampling results for the mineralized skarn exposed on TARGET # BE2 shown above include the following, note the traces of Platinum and Palladium:

Crystal Pass:
The Quantec Survey in this portion of the Boss Project consisted of three lines (labeled L3, L4 and L5) spaced at 750 m intervals (Figure 2). Two high-priority targets and a number of high-moderate and moderate priority targets that warrant diamond drill testing have been located. Positive chargeability and resistivity responses of varying dimensions occur on both sides of a zone that hosts intrusive dikes of quartz diorite and quartz monzonite composition sporadically exposed on surface (Figure 2).

Numerous other smaller targets have been identified in the area of Crystal Pass and also warrant diamond drilling.
