Calgary, Alberta - Boxxer Gold Corp. (TSXV-“BXX”) is pleased to provide an update on its current exploration program on the Buena Vista Joint Venture project located approximately 90 miles east of Reno. Drilling that was completed in July tested a deep induced polarization (IP) anomaly and associated mineralized showing in the central portion of the property. A total of 1,849 feet of drilling in two holes were completed (see April 10 and July 9, 2007 news releases). Following the drilling program, additional geologic mapping/outcrop sampling as well as surface and borehole source IP surveys were carried out in other areas of the property.
Significant Drilling Results:
DDH-BV07-5 was a vertical hole designed to test the deep (> 600’), modest to strong (up to 23ms) chargeability anomaly defined by both borehole source and surface IP surveys in the “feeder zone” area. The anomaly is associated with an irregularly, asymmetrically zoned copper-bearing pyritic halo intersected by previous drilling and mapped at surface. The borehole source IP survey suggested the sulfide halo may be enveloping a deeper higher grade core of disseminated manto-style copper mineralization. A portion of the halo containing disseminated to stockwork chalcopyrite crops out several hundred feet to the west of the anomaly and assayed 0.14% Cu over13 feet of section. The hole was centered on the strongest portion of the IP anomaly.
Three moderately dipping, stratigraphically stacked, barren strata-bound alteration (sodic-calcic) units were penetrated by the drillhole; a fourth was intersected from 826 feet to 898.2 feet. That unit, designated “D” is characterized by widespread and intense phyllitic (sericite, sericite – clay) alteration overprint that hosts low-grade disseminated to stockwork pyrite-bornite-chalcopyrite (1%-3% total) mineralization.
A second angled (-70˚) offset hole (BV07-6) was constructed to test the up-dip extent (to the west) of the mineralized unit intersected in BV06-5 and surface chalcopyrite showing. Alteration Unit D was intersected at a hole depth of 719.2 feet to 721.5 feet but found to be mostly faulted off at this location.

Post Drilling Geophysical Surveys
Additional borehole source and surface IP surveys were completed in the feeder zone area after the drilling program in an attempt to trace mineralized alteration Unit D. The borehole source survey utilized an electrode implanted just above the mineralized intercept in BV07-5. These data clearly show a trend of increasing chargeability (10ms to 18ms) to the southeast; a deep (>600’) IP zone 300 to 400 feet wide and 1,700 long was delineated on ground controlled by Boxxer.
Conclusions
A disseminated high-grade manto-style core at depth within the sulfide halo remains a reasonable target in the feeder zone area, based on drillhole results in BV07-5 and follow up borehole source and surface IP surveys. These data suggest that mineralized Unit D is open down dip to the east and along strike with sulfide mineralization increasing to the southeast. Further, this mineralized unit may correlate across a major structural zone westward to DDH-BV07-3 which was lost in a similar type of alteration. Additional deep drilling is warranted to test further the mineralized unit.
Additional Geophysical / Geological Surveys
Follow-up surface and borehole source IP surveys (BV07-5) have also identified two new chargeability anomalies on the property. The first is a deep (> 600’) anomaly on the northwest side of the property. The moderate (10ms) chargeability zone is linear near surface trending at least 1,900 feet in a northwest –southeast direction parallel to the strike of known andesite flow units mapped in this area. However, the borehole source IP survey suggests the anomaly is much larger (at least 3000’ long and 1,100’ wide), more irregular shaped and stronger (10ms – 18ms) at depth (>600’). Geologic mapping in this area which is mostly covered by thin colluvium, suggests this portion of the property is on an up-thrown fault block that is at a high level in the IOCG system. Most flow units show little or no alteration. At least two copper showings are immediately adjacent to the IP anomaly on a juxiposed fault block to the east. The showings consist of localized bornite and/or chalcopyrite disseminations and veinlets hosted in a strata-bound albite-Fe-carbonate-hematite alteration unit; assays are shown below (northwest showings). The new IP anomaly which is persistent in both surface and borehole source IP surveys may represent deep mineralized flow tops, breccias or permeable interflow sediment units at a higher stratigraphic level in the system.
The second anomaly was identified at the northeast end of the property. Mapping and sampling in this area located a narrow (10’ – 50’ wide), northwest-trending strata-bound albite-Fe-carbonate-hematite alteration unit. The unit has been traced at least 3000 feet along strike to the northwest. A continueous zone of mineralized outcrops over 300 feet long and containing fine-graded disseminated chalcopyrite occurs at the unit’s east end. The widest part of the zone had a weighted average of 0.35% Cu and 0.122ppm Au over 13 feet of section (true thickness). All assays from the mineralized zone are shown below (northeast showings). The zone is coincident with the strong (up to 18ms) chargeability anomaly that is open in both directions. Unaltered andesite flows form a structural footwall and hanging wall to the alteration unit; the mineralized section dips moderately down slope to the southwest under thin pediment cover.
Significant Outcrop Sample Assay Results:

Exploration Pan:
Additional follow-up drilling on the feeder zone target is planed. The newly identified IP will require additional surface IP follow-up surveys to define further potential drill targets. Each anomaly will be tested by diamond drilling.
Sample Preparation and Analysis:
All drill core and outcrop samples were prepared at the ALS Chemex laboratory in Winnemucca, Nevada. Prepared sample pulps were shipped to ALS Chemex in Vancouver, British Columbia for geochemical analysis (atomic absorption and ICP-AES methods). ALS Chemex’s quality system complies with the requirements for the International Standards ISO9001:2000 and ISO 17025:1999. Analytical accuracy and precision are monitored by the use of international and in-house standards. Additional quality control measures included insertion of blanks in all drill core sample batches submitted and requests for duplicate check assays from selected pulp or coarse-reject samples.
