Roxgold intersects 52.3 gpt au over 6.1 metres at QV1, extends strike length by more than 100 metres & completes initial QV1 metallurgy testwork program

TORONTO, Jan. 14, 2016 /CNW/ - Roxgold Inc. ("Roxgold" or "the Company") (TSX.V: ROG)  is pleased to announce results from its latest drilling program from the QV1 and QV Prime (QV') structures at the Bagassi South regional exploration target 1.8 km south of the 55 Zone.

Bagassi South Drilling

Drilling at QV1 focused on extending the mineralization encountered at this target in previous drilling (see Roxgold Press Release dated May 05, 2015, May 19, 2015 and Aug 11, 2015).  Previous results from this target include:

  • 23.6 gpt gold over 10.9 m and 8.2 gpt gold over 6.0 m in DDH YRM-15-DD-BGS-083
  • 7.5 gpt gold over 10.6 m including 22.2 gpt gold over 3.2 m in DDH YRM-15-DD-BGS-084
  • 10.4 gpt gold over 19.4 m including 25.1 gpt gold over 7.1 m in DDH YRM-15-DD-BGS-085
  • 8.9 gpt gold over 9.4 m including 36.1 gpt over 1.2 m in DDH YRM-15-DD-BGS-087
  • 11.0 gpt gold over 7.5 m including 33.7 gpt over 0.8 m and 19.4 gpt over 1.7 m in DDH YRM-15-DD-BGS-089
  • 13.7 gpt gold over 7.2 m including 13.7 gpt over 1.5 m and 40.3 gpt over 1.5 m in DDH YRM-15-DD-BGS-090
  • 14.5 gpt gold over 6.1 m in DDH YRM-15-DD-BGS-095.

This program, accounting for approximately 3,000 m of Reverse Circulation ("RC") and Diamond Drilling ("DD"), was successful in further extending the high grade QV1 mineralization along strike and down plunge from existing intercepts by approximately 100 metres in hole YRM-15-RD-BGS-104A (see Figures 1, 2 & 3).

"We are pleased with the results from this extension drilling program at QV1," stated John Dorward, President and CEO of Roxgold.  "We recommenced drilling this week with the goal of delivering a maiden resource on the QV1 structure in the second quarter."

The QV1 target at Bagassi South is located 1.8 kilometres to the south of the 55 Zone where Roxgold continues construction activities on the Yaramoko Gold Project.

No resources have yet been estimated for the QV1 target at this time.

Bagassi South Drill Program Results

The results announced today are from an 11 hole 3,000 m Diamond and RC drill program that was designed to test for mineralization to the south of the Bagassi dyke as well as evaluate the up-dip potential and infill gaps in the drilling to the north of the dyke. Holes were drilled with an RC pre-collar to approximately 10 m above their intended target depth and were subsequently competed with a diamond tail. Of this program, approximately 640 m of Diamond and 1,730 m of RC were drilled at QV1. At QV', 155 m of Diamond and 470 m of RC were completed.

All holes targeting the QV1 structure intersected the structure where expected. Holes were targeted to explore the south easterly plunging QV1 structure and enlarge the mineral envelope; hole 104A is the most southern intersect to date where the hole swung to the south intersecting high grade mineralization 100 m further south than previously encountered. The QV1 structure remains open down plunge and along strike (see Figures 4 & 5).

At QV', 2 holes were drilled to test for the continuity of the structure to the south east (see Figure 3). QV' is located within the hanging wall of the QV1 structure. Both holes intersected anomalous mineralization and structure consistent with the intersection in YRM-14-DD-BGS-056 (39.6 gpt gold over 4.5 m including 136.0 gpt gold over 1.3 m; see Roxgold Press Release dated Sep 08, 2014) and this structure remains open along strike and plunge to the south east.

Follow up drilling at QV1 has commenced with the aim of drilling out the mineralized envelope as currently defined with sufficient drill spacing to enable the completion a resource estimate.

Metallurgical Test Work Program Results

A preliminary metallurgical test work program was conducted on approximately 30kg of sample material from the QV1 target at Bagassi South.  Sample material was selected from drill core taken from previous drilling at QV1 and included 4 composite samples and 2 variability samples. These samples were selected from intervals along the strike length of the QV1 area and are representative of all mineralization types encountered at QV1 to date.

The metallurgical test work was completed in Perth, Western Australia by Ammtec ALS laboratories and at the program was designed to define the metallurgical characteristics of the high grade material from Bagassi South. Gravity response, leach kinetics, hardness, reagent consumption and overall potential recovery rates were assessed.

The metallurgical test results are consistent with the metallurgical response observed in ore from the Yaramoko 55 Zone deposit.

Bond Ball Mill Work Index Tests, to assess the ore hardness, were completed on the QV1 Composite and QV1 Ext Composite, returning values of 17.4 kWh/t and 18.0 kWh/t, respectively.  These values are comparable with the ore hardness results recorded at Yaramoko's 55 Zone.

Both the gravity-leach and whole ore leach recovery rates were comparable, with high recoveries being recognised whether inclusive of the gravity stage or not.

Paul Criddle, Roxgold's Chief Operating Officer commented, "We are very pleased with the preliminary metallurgical test results.  This initial stage program will provide the necessary foundation as we progress towards defining a maiden resource at this newly discovered mineralized area.  The excellent recovery rates and the consistency of the results across a broad grade range are reminiscent of the results of the more extensive test work program previously undertaken for the high grade 55 Zone, located less than two kilometres to the north."

Qualified Persons

Ben Pullinger, P.Geo, Vice President of Exploration for Roxgold Inc., and Paul Criddle, FAUSIMM, Chief Operating Officer for Roxgold Inc., are Qualified Persons within the meaning of National Instrument 43-101, having verified and approved the technical data disclosed this press release. This includes the sampling, analytical and test data underlying the information.

Quality Assurance/ Quality Control

The holes were RC pre-collars to approximately 10 metres above the target zone. From there, NQ2 diamond drill bits were used for drill holes reported in this press release. Company personnel are located at the drill site. Contractors and employees of Roxgold conducted all logging and sampling. The core was logged, marked up for sampling using standard lengths of two metres outside of the "zone" and adjusted to lithological contacts up to one metre within the "zone". Samples are then cut into equal halves using a diamond saw. One half of the core was left in the original core box and stored in a secure location at the Roxgold camp within the Yaramoko area. The other half was sampled, catalogued and placed into sealed bags and securely stored at the site until it was shipped to Act Labs and SGS Laboratories (the "Labs") in Ouagadougou. The core was dried and crushed by the Labs and a 150 gram pulp was prepared from the coarse crushed material. The Labs then conducted routine gold analysis using a 50 gram charge and fire assay with an atomic absorption finish. Samples returning over 5.0 gpt were also analysed by gravimetric analysis. Quality control procedures included the systematic insertion of blanks, duplicates and sample standards into the sample stream. In addition, the Lab inserted its own quality control samples.
