Highlights:

  • Further drilling to extend the 50C nickel trough discovery has confirmed significant nickel mineralization over 200 metres in strike and up to 120 metres in width.
  • New drilling north of the previously reported high grade 50C discovery hole G50-22-005E (11.6% Ni over 4.6 metres downhole) has intersected further high grade nickel mineralization, including intersections1 of:
    • G50-22-011NR: 3.2% Ni over 3.1 metres
    • G55-22-006NR: 5.1% Ni over 2.1 metres
    • G50-22-004NR: 2.1% Ni over 7.5 metres, including 4.0% Ni over 3.0 metres
  • Infill drilling of the 10C nickel trough, which lies adjacent to the 50C trough, has returned encouraging results that support the current Mineral Resource and include the following intersections1.:
    • G10-22-008NR: 3.8% Ni over 10.9 metres, including 5.2% Ni over 3.8 metres
    • G10-22-011NR: 4.2% Ni over 3.0 metres
  • Nickel mineralization in the Beta Hunt Gamma Block remains open to the southeast beyond the 10C and newly defined 50C nickel troughs, with an encouraging historic drill intersection of 11.4% Ni over 9.5 metres located 1 kilometre southeast of current Karora drilling.
  • Results from the 30C nickel trough drilling provide encouragement for an extension of the current Mineral Resource and include the significant results1:
    • B30-19-008NR: 2.0% Ni over 8.9 metres

TORONTO, March 1, 2022 /CNW/ - Karora Resources Inc. (TSX: KRR) (OTCQX: KRRGF) ("Karora" or the "Corporation") is pleased to announce that new nickel exploration results from the 50C nickel trough at Beta Hunt have extended the known strike length to over 200 metres (previously 150 metres, see Karora news release dated October 8, 2021). The new results include drilling along strike of the 50C discovery and the parallel 10C nickel trough.

Paul Andre Huet, Chairman & CEO, commented: "We are very pleased with the latest results received from our nickel drilling program at the 50C nickel discovery and parallel 10C nickel trough. The new drilling supports the extension of the 50C discovery to over 200 metres in strike length and up to 120 metres in width, all delivered in just 10 months since discovery (see Karora news release dated April 6, 2021). A key feature of the Beta Hunt Mine is the extensive existing mining infrastructure. This provides us with the advantage of moving very rapidly from initial discovery to Mineral Resource definition and, ultimately, with the goal of mining.

Drilling results from the 10C nickel trough further support our objective to upgrade and extend the existing 10C nickel Mineral Resource, which forms part of the current Beta South Mineral Resource. Our team is now working on a new nickel mineralization model for the Gamma Block that will utilize the new drill results from both 50C and 10C to enhance identification of drill-ready targets. We will use this model to support an updated nickel Mineral Resource incorporating the 50C discovery and 10C upgrade and extension during the second quarter of 2022.

The potential growth of the 50C and 10C nickel mineralization is not capped at the current strike length. A historic drill intersection of 11.4% Ni over 9.5 metres is located approximately 1 kilometre southeast of our current drilling, supporting our hypothesis that nickel mineralization may be significantly more extensive – an exciting prospect.

With respect to the new 50C nickel discovery, which is located just 140 metres from existing mine development, we expect to move rapidly to grow our nickel production and, increase our nickel by-product credits which would then further reduce our overall AISC gold production costs in future years. Mine planning for the Gamma Block is underway with a view to bring these new nickel areas into production as soon as practicable with the goal of first mining taking place in the first half of 2023.

Lastly, new drill results received from the 30C nickel trough, located proximal to the Larkin Gold Zone, demonstrate the potential to further extend the nickel Mineral Resource in this area. To be able to move this quickly from discovery into production yet again demonstrates the infrastructure advantage we enjoy at Beta Hunt."

Gamma Block - 50C and 10C Nickel Troughs

The drill program designed to test and extend the recently discovered 50C nickel trough and upgrade the 10C nickel Mineral Resource was completed. Drilling totaled 40 holes for 6,505 metres. All results have now been received. The original 50C discovery was highlighted by the previously reported intersection of 11.6% nickel over 4.6 metres (downhole) in drill hole G50-22-005E.

50C Drilling: Drilling both north and south along strike from the discovery intersection (hole G50-22-005E) now supports continuous nickel sulphide mineralization over 200 metres in strike length (Figure 1). The new intersections are spaced on drill fans targeted to intersect the trough on 30 to 50 metre line spacings. Results from drill hole G55-22-002NE on the discovery section were received and show the 50C trough to be up to 120 metres in width (Figure 2).

Assay highlights include:

    • G50-22-011NR: 3.2% Ni over 3.1 metres1
    • G50-22-004NR: 2.1% Ni over 7.5 metres1, including 4.0% Ni over 3.0 metres
    • G55-22-006NR: 5.1% Ni over 2.1 metres
    • G50-22-014NE: 3.7% Ni over 2.0 metres
    • G50-22-010NR: 2.7% Ni over 3.2 metres
    • G50-22-002NE: 1.3% Ni over 1.6 metres

1.       Downhole intervals. True widths cannot be determined with currently available information.

Nickel mineralization on the targeted basalt/ultramafic contact has been logged as massive, matrix-supported and disseminated nickel sulphide and indicate an intact nickel trough.

As previously referenced (see Karora news release dated October 8, 2021), porphyry intrusions in the northern drill sections have replaced parts of the nickel contact mineralization position as drilling moves north toward the Gamma Island Fault. Overall, results show an extensive, wide and continuous nickel trough supporting the discovery section (Figure 3).

10C Drilling: The 10C nickel trough is a parallel trough east of the 50C and is part of the Beta South Mineral Resource (see Technical Report Higginsville-Beta Hunt Operation, Eastern Goldfields, Western Australia dated January 29, 2021 available under Karora's profile at www.sedar.com). The 10C drill program is designed to upgrade the existing Inferred Mineral Resource and extend known nickel mineralization. The 10C results are highlighted by an intersection of 3.8% nickel over 10.9 metres, including 5.2% nickel over 3.8 metres in drill hole G10-22-008NR (Figure 2). The atypical thickness in this intersection is believed to be due to thrust-related stacking of the nickel sulphide horizon. This is not an unusual geological setting at Beta Hunt where this type of structural repetition is evident from historical mining of these nickel deposits. Overall, assay results to date support the current Mineral Resource.

Significant results1 returned to date from the 10C drilling are highlighted below:

  • G10-22-008NR: 3.8% Ni over 10.9 metres, including 5.2% Ni over 3.8 metres
  • G10-22-011NR: 4.2% Ni over 3.0 metres
  • G10-22-007NR: 3.3% Ni over 2.2 metres
  • G10-22016NR: 3.3% Ni over 2.3 metres

1.       Downhole intervals. True widths cannot be determined with currently available information.

The 50C and 10C recent drill results continue to reinforce the potential for a significant nickel mineralized system similar to the Beta Nickel Block which historically produced approximately 33,000 nickel tonnes. 

With the new 50C area only 140 metres from existing mine development, this represents a significant growth opportunity for by-product nickel production at Beta Hunt. Mine planning is underway to ensure sufficient ventilation, infrastructure and resources are available to enable development to commence as soon as possible. 

All nickel assay results from the first stage of drilling the Gamma Block have now been received and work has commenced on producing a revised nickel mineralization model to assist in designing a follow-up drill program planned for the second half of 2022. An updated nickel resource that includes the 10C and newly defined 50C nickel trough is expected to be completed during the second quarter of 2022.

30C Nickel Trough and Western Flanks Nickel 

Outside of the Gamma Block drilling, nickel results were also received for drill holes designed to extend and upgrade the 30C nickel resource. This included dual purposing of drill holes to upgrade the Western Flanks Gold resource by extending the gold focused holes to also test for nickel mineralization on the ultramafic/basalt contact.

Results from the 30C drilling provide encouragement for an extension of the current Mineral Resource and include the significant results1 listed below:

  • B30-19-008NR: 2.0% Ni over 8.9 metres
  • B30-19-018NR: 2.4% Ni over 2.3 metres
  • B30-19-020NR: 3.9% Ni over 1.3 metres

1.       Downhole intervals. True widths cannot be determined with currently available information.

The limited amount of gold-targeted drilling extended to test for nickel mineralization above the northern end of the Western Flanks Mineral Resource confirmed the presence of nickel sulphide mineralization on the basalt/ultramafic contact.

Follow-up work, including reviewing of all historical drill data, is planned to fully assess the nickel potential prior to the next stage of follow-up drilling. The best result received from the new Western Flanks extension drilling is shown below and highlights the potential for a new nickel trough discovery at Beta Hunt by Karora:

  • AW17LN-17AR: 1.2% Ni over 2.0 metres1

Compliance Statement (JORC 2012 and NI 43-101)

The disclosure of scientific and technical information contained in this news release has been reviewed and approved by Stephen Devlin, FAusIMM, Group Geologist, Karora Resources Inc., a Qualified Person for the purposes of NI 43-101.

At Beta Hunt all drill core sampling is conducted by Karora personnel. Samples for gold analysis are shipped to SGS Mineral Services of Kalgoorlie for preparation and assaying by 50 gram fire assay analytical method. All gold diamond drilling samples submitted for assay include at least one blank and one Certified Reference Material ("CRM") per batch, plus one CRM or blank every 20 samples. In samples with observed visible gold mineralization, a coarse blank is inserted after the visible gold mineralization to serve as both a coarse flush to prevent contamination of subsequent samples and a test for gold smearing from one sample to the next which may have resulted from inadequate cleaning of the crusher and pulveriser. The lab is also required to undertake a minimum of 1 in 20 wet screens on pulverised samples to ensure a minimum 90% passing at -75µm. Samples for nickel analysis are shipped to SGS Australia Mineral Services of Kalgoorlie for preparation. Pulps are then shipped to Perth for assaying. The analytical technique is ICP41Q, a four acid digest ICP-AES package. Assays recorded above the upper detection limit (25,000ppm Ni) are re-analyzed using the same technique with a greater dilution (ICP43B). All samples submitted for nickel assay include at least one Certified Reference Material (CRM) per batch, with a minimum of one CRM per 20 samples. Where problems have been identified in QAQC checks, Karora personnel and the SGS laboratory staff have actively pursued and corrected the issues as standard procedure.

Cautionary Statement Regarding the Higginsville Mining Operations
A production decision at the Higginsville gold operations was made by previous operators of the mine, prior to the completion of the acquisition of the Higginsville gold operations by Karora and Karora made a decision to continue production subsequent to the acquisition. This decision by Karora to continue production and, to the knowledge of Karora, the prior production decision were not based on a feasibility study of mineral reserves, demonstrating economic and technical viability, and, as a result, there may be an increased uncertainty of achieving any particular level of recovery of minerals or the cost of such recovery, which include increased risks associated with developing a commercially mineable deposit. Historically, such projects have a much higher risk of economic and technical failure. There is no guarantee that anticipated production costs will be achieved. Failure to achieve the anticipated production costs would have a material adverse impact on the Corporation's cash flow and future profitability. Readers are cautioned that there is increased uncertainty and higher risk of economic and technical failure associated with such production decisions.
