Beta Hunt Gold Mineralized System Continues to Grow

 

 

 

 

 

RNC Minerals (TSX: RNX) (RNC) is pleased to announce results of the recently completed Exploration drilling program that was drilled from underground positions within the Beta Hunt mine. A total of six holes were completed for 2,190 m. Drilling targeted three shear zones – Fletcher (one hole), Western Flanks north (four holes) and East Alpha (1 hole).   Drilling was designed to test conceptual targets, and to investigate the potential for extension of the Western Flanks Mineral Resource to the north. The balance of the original 5,000 m planned for exploration drilling has been deferred for the time being to focus on other priorities. Exploration at Beta Hunt will continue to focus on the identification of gold and nickel drill targets based on a review of historic (and current) drill holes, supported by an improved understanding of the mineralization and geological controls generated by the 2019 resource definition drill program.

 

Paul Andre Huet, President and CEO of RNC, commented “The extension of the Western Flanks mineralization is very positive for RNC, as it is consistent with our view regarding the potential for continued mineral resource additions  at Beta Hunt. With our recent results, we have extended the strike length of the Western Flanks shear zone by an additional 200 m to the north of the current resource base. The potential for the Fletcher zone to be added as Beta Hunt’s third major mineralized zone is progressing well based on our recent drilling, leading us to identify further high priority drilling targets along the shear. Our drilling campaign this year resulted in a major increase (+395%) to our Measured and Indicated resource base, now totaling 944 koz. These ounces came at an extremely low discovery cost of $7.30 per oz. Overall, I am extremely pleased with the ongoing drilling program, which has intersected mineralized zones beyond our already significantly increased mineral resource base.”

 

Fletcher

 

In 2016, an exploration drill hole, WF14-98, first intersected the Fletcher Shear Zone (FSZ) – refer RNC news release dated July 6, 2016. Drilling tested a conceptual gold target using the A-Zone and Western Flanks shear zones as structural analogues. Drilling confirmed the existence of a third significant mineralized shear zone within the Beta Hunt sub-lease with the discovery hole yielding two mineralized intervals within the FSZ – results reported below use estimated true thicknesses1.

 

  • WF14-98 (Lode A) – 2.67g/t Au over 6.2 m including 3.1g/t Au over 3.1 m; and
  • WF 14-98 (Lode B) – 2.32g/t Au over 11.2 m, including 3.8 g/t Au over 4.8 m.

 

The recent drill hole, FZ350-001 (642.1 m), targeted the down-dip extension of the FSZ, 150 m down dip of the WF14-98 intersection. The follow-up hole was collared on the 350L crosscut of the Western Flanks. Drilling was successful in intersecting the extension of the FSZ in the targeted position (Figure 2). The FSZ comprised biotite-pyrite altered, foliated and irregularly quartz veined basalt – similar to that found at Western Flanks. Assay results confirmed a broad zone of gold mineralization of similar widths to the up-dip hole:

 

  • FZ350-001: 1.21 g/t Au over 17.5 m including 5.87g/t over 0.54 m

 

The lower gold grades compared to WF14-98 appear related to reduced quartz veining and a 4.5 m wide porphyry intruding into the FSZ at this location which carries an average grade of 0.3 g/t Au.

 

The confirmation that the FSZ comprises a broad mineralized zone provides added confidence and evidence that the FSZ is Beta Hunt’s third major mineralized shear zone system. Drilling has confirmed it has over 150 m of down dip extent, while potential remains for the system to extend over 2 km of strike.

 

Potential also exists for nickel mineralization to occur along the basalt/ultramafic contact, directly above the Fletcher shear zone in a similar geological setting to the nickel trough mineralization found directly above the A Zone and Western Flanks shear zones. This target will be considered as part of the next phase of drilling at Beta Hunt which is currently under consideration by management.

Western Flanks (north)

 

Much of the success of the recently completed resource definition program in defining a Mineral Resource of 710,000 oz (Measured and Indicated) and 250,000 oz (Inferred)1 was built on the extension to the north of the previously defined resource. To further test the northern strike potential of the Western Flanks, four exploration holes (1,229.4 m), tested for mineralization on sections 100 m and 200 m north of previous drilling. All four holes intersected Western Flanks shear-style mineralization, with the strongest intersections on the most northern section as follows (all intersections are estimated true widths).

 

  • WFN-084: 1.2g/t Au over 9.9 m and 3.2 g/t Au over 3.5 m
  • WFN-085: 2.2 g/t Au over 3.4 m
  • WFN-086: 2.0 g/t over 21.2 m including 2.6 g/t Au over 8.4 m (including 22.0 g/t over 0.3 m)
  • WFN-087: 2.3 g/t over 6.2 m including 7.8 g/t Au over 0.5 m

Drill results show the Western Flanks shear zone continues to extend a further 200 m further north of previous drilling and highlights the potential for significant additions to the recently completed mineral resource estimate. The Western Flanks mineralized system now extends continuously over 1.4 km in strike to a depth of 150 m to 250 m below the basalt contact and remains open at depth and along strike to the north. 

 

East Alpha

 

Drill hole EA63-031 (318.1 m) was the first hole designed to specifically test the East Alpha shear zone interpreted to be associated with, and directly below, the East Alpha nickel trough. Drilling targeted 100 m below the ultramafic/basalt contact and historic drill hole EA63-13 (4.8 m @ 5.9 g/t Au down hole). Best result recorded in the drill hole was 0.53 g/t Au over 3.3 m (est. true width) associated with sheared basalt and associated quartz breccia veining. The main East Alpha shear was intersected from 135 m to 161 m (down hole) and comprises sheared basalt hosting extensional quartz-carbonate veining and pyrite alteration. Early results (0.8 g/t Au from 157 m to 158 m down hole) although not showing mineable grade do highlight the need for further evaluation of East Alpha geology to fully understand the results of this initial hole

 

Nickel

 

Work has commenced on a review of existing nickel mineral resources and targets to take advantage of the current nickel price with the objective of supplementing gold revenue. The nickel mineral resources for Beta Hunt previously reported by RNC (effective as of February 1, 2016) are- Measured and Indicated 379 kt @ 4.2% Ni (15,840 t Ni), Inferred 216 kt @ 3.4% Ni (7,400 t Ni). Since the effective date of this estimate (February 1, 2016), RNC has processed a total of 124 kt grading 2.6% Ni (3,354 t contained Ni) from the Beta Hunt mine.

 

Beta Hunt has the advantage of having existing mine development adjacent to nickel mineral resources that would provide the potential for short term production without interfering with the planned gold production. The operation is currently assessing requirements to allow for nickel production to be placed on a more sustainable basis.

 

Preliminary review of historic drilling is already providing significant encouragement. An example of work to date has already indicated continuous, high-grade nickel mineralization located above the Western Flanks gold Mineral Resource (Figure. 4) This mineralization is outside of any nickel mineral resources previously reported by RNC and occurs parallel to the historically-mined D Zone nickel trough (above A Zone gold Mineral Resource) 150 m to the east.

 

In addition to the nickel mineralization on the ultramafic/basalt contact, there is also the potential for coarse gold to occur on or just below this contact, as occurred on the A-Zone contact. Historical records show 3,295 oz gold was mined from specimen stone by WMC at or just below the nickel contact at the top of the A Zone shear. Coarse/Specimen gold mineralization is intermittently found where the mineralized shears intersect iron sulphide-rich contacts represented by the main basalt/ultramafic contact and pyritic interflow sediment.

 

Going Forward

 

The reported drilling results will contribute to our updated exploration strategy for Beta Hunt. The strategy aims to continue to grow the Western Flanks shear zone, test additional areas along the 2km strike potential of the FSZ and target more prospective segments of  the East Alpha shear. To support this process a systematic review and re-sampling program on all historical core has commenced to drive our updated geological model for mine planning and future drill program design. 

 

With respect to nickel, work will continue on re-evaluating existing resources and exploration opportunities with the aim of prioritizing future work which most likely will include drilling to test newly identified targets as well as upgrading/extending current nickel resources.
