TORONTO, Dec. 16, 2020 /CNW/ - Karora Resources Inc. (TSX: KRR) ("Karora" or the "Corporation") is very pleased to announce a 334% increase in consolidated gold Proven and Probable ("2P") Mineral Reserves to 1.33 million ounces for its Beta Hunt and Higginsville operations in Western Australia. The updated Mineral Resource and Reserve estimate is effective as of September 30, 2020.
The Corporation is also pleased to announce new consolidated Measured and Indicated ("M&I") gold Mineral Resources of 2.52 million ounces, representing a 167% increase. The Mineral Resource and Reserve update announced today does not include the high grade Spargos Reward Project, which is expected to be completed in the first half of 2021.
Paul Andre Huet, Chairman & CEO, commented: "The 334% increase in the 2P gold Mineral Reserves to 1.33 million ounces and 167% increase in gold Mineral Resources to over 2.5 million ounces is an outstanding achievement for Karora. This update marks the establishment of our very first consolidated Mineral Resource and Reserve estimate across our two primary assets in Beta Hunt and Higginsville, completed on schedule despite significant drilling delays associated with COVID-19 precautions during the middle of the year. Importantly, the very large increases are net of mining depletion through to the end of the third quarter of 2020.

At Beta Hunt, where we announced our maiden Karora Mineral Reserve estimate last year, we added 176,000 ounces, representing a strong 57% increase over 2019. Grades remained robust, however we are certainly excited to further define the newly discovered high grade Larkin Zone announced in mid September which will be included in our 2021 estimate next year.
At Higginsville, when compared to the previous historical estimate completed by Westgold Resources in 2018, our 2020 drilling and re-estimation efforts added nearly 500,000 ounces, increasing 2P Mineral Reserves by 130%.
At Higginsville Central, where mining will be focused over the short and medium term, we have outlined a Reserve of 218,000 ounces at high open pit grades of 2.0g/t. This Reserve is backed by a high grade M&I Mineral Resource of 382,000 ounces at 2.8g/t, which we expect to be further bolstered by mid-2021 via the addition of feed from our high grade Spargos Reward open pit into the Higginsville plant.
Due to the very strong recent drilling results announced in November, we now expect to have an updated Mineral Resource and Reserve estimate completed at Spargos in the first half of 2021. Next year will also see further drilling across all main projects, including the highly prospective targets at Lake Cowan and the first of the underground mines at Higginsville. After our first year of ownership, Higginsville is certainly shaping up to be both a high grade and long-lived operation.
While this is an outstanding start to our Mineral Resource and Reserve growth plan, I am even more encouraged by the exciting exploration targets we have selected for drilling in 2021. Moving forward, this updated Mineral Resource and Reserve estimate will form the basis for Karora's organic growth strategy which I look forward to outlining to the market during the first quarter of next year."

Higginsville
Reporting for the Higginsville Mineral Resource and Reserve inventory is split into two main areas – Higginsville Central and Higginsville Greater. The former covers Mineral Resources within a radius approximately 10 kilometres of the Higginsville mill while Higginsville Greater covers all Mineral Resources that fall outside the Higginsville Central area (see Figure 1).
Higher grade Higginsville Central will form the basis of the short and medium term mine plan at Higginsville which will be outlined as part of Karora's organic growth plan early next year. Importantly, numerous brownfields opportunities remain to target significant additional high grade, near term additions at Higginsville Central in 2021 including, but not limited to, the Aquarius Project and underground at Two Boys.

During 2020, Karora completed a comprehensive re-estimation of the Higginsville Mineral Resources and Reserves, replacing the historical estimate previously compiled by Westgold Resources as at June 30, 2018. The Higginsville Mineral Resource and Reserves are now part of Karora's consolidated Mineral Resource and Reserves.
At Higginsville, gold Mineral Reserves increased by 478,000 ounces, or 130% over the previously reported Historical Mineral Reserves of 367,000 ounces (see Karora's Technical Report dated February 6, 2020 available under Karora's profile on Sedar.com). Higginsville Central, the focus of near and medium term mining, hosts a high grade Mineral Reserve of 218,000 ounces at 2.0 g/t.
Measured and Indicated gold Mineral Resources at Higginsville increased by 242,000 ounces, or 20%, compared to the Historical Measured and Indicated Mineral Resource of 1,223,000 ounces. At Higginsville Central, Resource grades improved to a strong 2.8g/t (382,000 ounces), highlighting the success of Karora's early 2020 focus on upgrading the Historical Mineral Resource for short-term production mining options.
For 2021, exploration and resource definition drilling at Higginsville is planned to upgrade and extend short-term mining production targets (<2 years) in Higginsville Central, underpinned by a strong commitment to greenfield exploration targeting significant new discoveries across the 1800km2 property. The latter is demonstrated by the recent expansion of drilling activities on the underexplored Lake Cowan area based on targets identified through regional gravity/aeromagnetic surveys. 2021 will also see a renewed focus on resource definition and exploration drilling at Spargos Reward ahead of initial mining by mid year.

Gold Mineral Reserves at Beta Hunt increased by 176,000 ounces from the November 1, 2019 Mineral Reserve estimate, an increase of 57%.
Gold Mineral Resources at Beta Hunt continued to grow through a well supported and targeted drilling program. Measured and Indicated Mineral Resources increased by 111,000 ounces, or 12% compared to the 2019 Measured and Indicated Mineral Resource estimate.
As with the 2019 estimate, it is important to note that high grade coarse gold discoveries at Beta Hunt associated with the shear zone / Lunnon Sediment intersection horizon, such as the Father's Day Vein are not represented in the resource model due to the extreme nuggety nature of this type of mineralization.
During 2020, exploration and resource definition activities at Beta Hunt were focused on infill and extensional drilling of the A Zone and Western Flanks. Two new discoveries were announced on September 8 and September 10: a new footwall zone in the main Western Flanks shear and the new high grade Larkin Zone discovered south of the Alpha Isla Fault. The Larkin Zone is similar in style to the A Zone and Western Flanks deposits north of the Alpha Island Fault and is interpreted as the southern fault off-set extension of the Western Flanks. This newly discovered zone requires further drilling before a resource estimate can be completed and is expected to be included in the 2021 update.
For 2021, resource definition drilling at Beta Hunt will prioritize the Larkin Zone as well as continue to extend and upgrade the Western Flanks and A Zone resources building on results from the 2020 program. Exploration drilling at Beta Hunt will test the along-strike continuity of the A Zone north and up-plunge of the existing resource, and the along-strike continuity of the Fletcher Zone, which is interpreted as a structural analogue to Western Flanks.

2020 marked the re-invigoration of the nickel by-product opportunity at Beta Hunt. After a four-year pause in nickel focused drilling, a targeted and well-planned exploration drilling program successfully discovered and defined the 30C Nickel Trough located between the two historical work areas of Beta and Beta West. The 30C trough is the first new nickel discovery at Beta Hunt in 13 years (see Karora news release dated September 10, 2020). Although only partially drilled out, this new discovery forms part of the current nickel Mineral Resource.

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.
