TORONTO (miningweekly.com) – The TSX-V-listed stock of Canamex Resources on Monday jumped more than 30% after the company officially released the results of reverse circulation drilling at the Bruner gold project, located in Nye County, Nevada, which returned 47.3 m grading 3.44 g/t gold.

The Vancouver-based explorer said the latest set of results confirmed the presence of a higher-grade zone that had yet to be properly quantified under Canadian National Instrument 43-101-compliant rules.

Trading in the company’s TSX-V-listed stock was on Friday halted at the company’s request, after it became apparent that news of the positive exploration update had reached certain investors before the company officially published it on Monday.

Canamex on Monday reported that drill hole B-1425, drilled into the East zone of the historic resource area, returned 44.2 m grading 6.97 g/t, within which a high-grade interval from 18.3 m to 25.9 m, grading 27.91 g/t gold and 327.3 g/t silver, was found.

The East zone remained open along strike to the north and south and was mainly untested by drilling, with work under way to assess the best access to drill stations to continue drilling the open extensions.

Other holes in the East zone included hole B-1424, which returned 47.3 m grading 3.44 g/t gold.

On the section containing the holes, the East zone was found to trend in a northerly direction and to be about 30.5 m wide, 61 m thick and lying within 6 m of the surface, Canamex said.

Canamex started its 2014 summer drilling campaign at the Bruner project early in March, after closing a $2.16-million financing with NYSE-listed Gold Resource Corp.

The company had also in recent months reported other high-grade intersections at the Bruner deposit, such as an interval of 70.1 m grading 3.17 g/t; and 6.1 m grading 11.24 g/t gold and 203.975 g/t silver within an interval of 41.2 m grading 2.078 g/t gold and 39.5 g/t silver.

Canamex is also focused on its Aranka North land package, in a highly prospective gold region in Guyana, South America, north-east of the major gold discoveries by Guyana Goldfields at Aurora and Aranka/Sulphur Rose. Under a 2011 option agreement, Canamex in June secured a 100% interest in the project after spending $1-million in exploration last year and issuing the last stage of share payments to GMV Minerals.

The property is currently under care and maintenance and field activities have been curtailed until further notice.

Canamex’s TSX-V-listed stock reached an intraday high of C$0.17 a share, before settling at C$0.16 apiece.
