Cangold Reports on Phase I Drilling Program at Plomo
VANCOUVER, BRITISH COLUMBIA–(Marketwire – Sept. 8, 2008) – CANGOLD LIMITED (TSX VENTURE:CLD) (the “Company”) has completed the Phase I core drilling program on the Plomo Project in northwestern Sonora, Mexico. The objective of the first-pass drilling was to gain a better understanding of the structural control of the gold mineralization within the 5 by 3 kilometre structural corridor identified by surface mapping and sampling, and to look for areas where the flat-lying gold-bearing structures coalesce into a larger zone with resource potential.
The Phase 1 drilling program comprised 1,498.5 metres in 10 widely spaced holes. Targets tested in this program included the gold-bearing, altered, low angle structures of Banco de Oro (1 hole), Pavorreal (6 holes), San Perfecto (2 holes), and Bonancita (1 hole) zones. In most holes, the targeted structures were intersected as planned and, to some degree, were gold-bearing.
Hole SP08-001, drilled immediately below the Banco de Oro workings (up to 298.0g/t gold), did not intersect the structure, likely due to a fault offset. Drill holes SP08-002 and SP08-003 were drilled at San Perfecto (see drill-hole map on the Company web-site at www.cangold.ca). The low angle structural zones noted on surface were intersected and show variable intensity of fracturing, brecciation, chloritization, quartz veining, silicification and disseminated pyrite. SP08-002 intersected 4.0 metres grading 0.92g/ t gold starting at 5.7 metres. SP08-003 was more intensely fractured and altered and intersected 11.65 metres grading 0.66g/t gold starting at 18.3 metres, including 2.28g/t over 2.0 metres. Drill intersections are believed to represent true widths.
Core holes SP08-004 to SP08-009 were drilled in the Pavorreal area and intersected wide sections of intense alteration. SP08-006 intersected 30 metres of well foliated rock with tourmaline and hematite-jarosite alteration but yielded no significant assays. Holes SP08-005 and SP08-008 intersected wide intervals of silicified, fractured, and pyritic diorite but contained only narrow intervals of gold mineralization with anomalous copper, lead and zinc (see table below). SP08-010 was drilled at Bonancita with the objective of hitting the very fractured/sheared pyritic zone observed on surface. It intersected 130 metres of sheared and crackle-brecciated andesite, with disseminated pyrite and sporadic brecciated quartz veins but returned no significant assays.
The Phase I widely spaced drilling at Plomo has demonstrated that the flat lying structures observed on surface play an important role in localizing gold mineralization. It would appear that another set of controls, such as cross-cutting structures, is required in order to upgrade the gold. As such, detailed geological mapping and rock sampling continued in the San Perfecto area after the drilling was completed, with a particular effort towards identifying major structures, alteration types and geological units in order to better discern the spatial relationships and controls of the gold mineralization. This work continues to outline significant gold mineralization, over an area approximately 400 metres across, associated with tourmaline-sericite alteration, gossan, and low angle structures in diorite and granodiorite east of SP08-003. Of 21 new chip channel samples collected across veins, structures, and more intensely altered areas, 13 assayed greater than 0.3g/t gold, and of those 5 were greater than 1.0g/t gold.
At Pavorreal, where widespread gold was encountered in surface sampling yet no significant values encountered in the subsequent drilling, a similar program of detailed geological, alteration and structural mapping is proposed. A new compilation of all this data will then be used to generate new targets for future drilling.

In a regional context, gold mineralization at the Plomo Project is believed to be related to the Mojave-Sonora Megashear (MSM). The MSM is a northwest-trending left-lateral, strike slip fault zone up to 5 kilometres wide and extending for hundreds of kilometres through northern Sonora, southern California and Arizona, and is interpreted to transect the southwest corner of the Plomo Project area. Many of the gold mines and prospects in Sonora occur within or are adjacent to the boundary of this regionally extensive structure, including Mexico’s largest gold mine, the Penoles / Newmont La Herradura deposit, which lies 25 kilometres to the west of Plomo and contains a global resource of 104,063,824 tonnes averaging 0.84 g/t gold (Penoles 2006 Annual Report). Other gold mines along the MSM include La Choya, and El Chanate in the Caborca region of north- western Sonora, and Mesquite and Picacho in the Yuma area of south- western Arizona and south-eastern California. The targets at Plomo are low grade, high-tonnage fault-related gold deposit amenable to open pit mining and heap leaching, similar to the aforementioned mines. The relationship of gold mineralization to flat-lying structures is typical of deposits within the MSM and the Company is encouraged by the confirmation of this relationship on the Plomo Property.
The 4,279 hectare Plomo Project lies within the Altar desert of north-western Sonora, approximately 320 kilometres northwest of Hermosillo, Sonora. It is easily accessible by paved highway and secondary gravel roads. Cangold is earning a 100% interest in the Plomo Property, subject to a 2% NSR.
Robert F. Brown, P. Eng and Vice-President of Exploration for Cangold and its wholly owned subsidiary, Coboro Minerales de Mexico, S.A. de C.V., is designated as the Qualified Person for the Plomo Project under the meaning of NI 43-101 and has reviewed this news release. Samples were assayed at SGS Labs in Durango. The Company’s QA/QC program includes the regular insertion of blanks, splits, and standards into the sample shipments.
