233.9 g/t Gold Roxgold Drills 233.9 g/t Gold Over 4.5 Meters (3.58 True Width) at 237 Meters Depth and Confirms High Grade Gold Mineralization Below 400 Meters at 55 Zone
Thursday, October 25, 2012
TORONTO, ONTARIO--(Marketwire - Oct. 25, 2012) -Roxgold Inc. ("Roxgold" or the "Company") (TSX VENTURE:ROG) -
Roxgold is pleased to announce the most significant intercept to date from the drill program at its 100% owned Yaramoko gold deposit in West-Central Burkina Faso.
Diamond drill hole 223 which intersected 233.89 gpt gold (uncut) over 4.5 meters (3.58 meters true width) from 237.6 meters to 242.0 meters, represents the most significant intercept within the 55 Zone to date.
The results released today cover 109 holes totalling 42,390 meters of drilling. This includes 70 holes from the 55 Zone, 10 holes with pending results, and 39 holes from the regional drilling.
The highlights included in today's release are;
- The 55 Zone remains open at depth.
- Three drill rigs are engaged in a step-out discovery and definition program.
- The previously reported drill core assay backlog will be eliminated within three weeks.
- Since the management transition on September 25th, 11,720 drill core samples have been assayed with 5,965 core samples remaining in the backlog.

Geological Interpretation
Orix Geoscience was contracted to prepare a geological interpretation of the 55 Zone. Their work confirms an easterly plunge to the ore body that remains open at depth. The Company is using this model to plan its current and future drilling and updating it as new information is gathered.
The very deep drilling initiated in July/ August has confirmed the presence of quartz veins at depth. These veins have returned no significant results and it appears that the drill holes targeted are under the plunge of the ore body. However, this drilling is not considered to have downgraded the prospectivity of the 55 Zone at depth.
The three diamond core rigs onsite are now focusing on step-out holes designed to expand known mineralization from between 400 to 700 meters vertical depth.
Regional Results
Regional work has been deferred pending the return, compilation and assessment of all outstanding assays. Roxgold strongly believes in the potential of the Yaramoko Concession which covers 167 sq km and plans to implement an aggressive regional exploration program in 2013.

John Dorward, Interim CEO commented:
"The results we have released today have given us confidence that the upper sections of the 55 Zone ore body are very robust and we are encouraged by results from deeper sections which remains open down plunge and to the east."
Transition to New management
Following the election of a new board on September 25th, 2012 and the appointment of John Dorward as Interim CEO the transition has progressed smoothly without interruption. A comprehensive update of transition activities will follow within the next few weeks.
Quality Assurance/Quality Control and Qualified Person
Drill holes reported in this press release were drilled using HQ and NQ2 sized diamond drill bits. Contractors and staff working for Roxgold conducted all logging and sampling. The core was logged, marked up for sampling in lengths of up to 2 meters. "Zone Samples" are sampled on intervals down to 30 cm depending on the core length of the intercept. The core is then cut into equal halves using a diamond saw. One half of the core was left in the original core box and stored at the Roxgold compound in Koussaro. The other half was sampled, placed into sealed bags and securely stored at the site until it is shipped to a certified lab in Ouagadougou or Canada. "Zone Samples" have been typically sent to TSL laboratories in Saskatoon while non "Zone Samples" have been shipped to Actlabs' Ouagadougou facility. The core is dried and crushed by the labs, and a 150 gram pulp is prepared from the coarse crushed material. The labs conduct routine gold analysis using a 50 gram charge and fire assaying with atomic absorption finish. Quality control procedures included the systematic insertion of blanks, duplicates and sample standards into the sample stream at the rate of one duplicate or one certified reference blank or standard per 11 samples. In addition, ALS and Actlabs insert their own standards, blanks and duplicates as per internal company procedures.
Pierre Desautels, P.Geo, a Qualified Person within the meaning of National Instrument 43-101 who is an independent consultant to the company, has verified and approved the data disclosed in this release. This includes the sampling, analytical and test data underlying the information.
