Revised production schedule reflects higher plant throughput capability; raising 2020 guidance

(All amounts are in U.S. dollars unless otherwise stated)

TORONTO, Aug. 06, 2020 (GLOBE NEWSWIRE) -- Teranga Gold Corporation (“Teranga” or the “Company”) (TSX: TGZ) (OTCQX: TGCDF) is pleased to report an updated life of mine (“LOM”) plan and new 2020 guidance for its Wahgnion Gold Operation (“Wahgnion”), located in southwest Burkina Faso, West Africa.

Since achieving commercial production on November 1, 2019, Wahgnion’s processing plant has performed approximately 25% above nameplate capacity for throughput and gold recovery, resulting in higher than planned production. As such, Teranga has updated the LOM plan to accommodate the higher plant throughput capability, increasing Wahgnion’s average annual production by 25% and reducing the mine life to 10 years. With a goal of extending the mine life to 15 years, Teranga has commenced a multi-year drilling and exploration campaign around three of the existing deposit areas and at more than a dozen promising targets at Wahgnion.

Teranga has also increased Wahgnion’s 2020 guidance for gold production to between 150,000 and 165,000 ounces, up from earlier guidance of 130,000 to 140,000 ounces. The higher guidance for 2020 is based on mill throughput of between 3.0Mtpa and 3.2Mtpa and total material movement of between 22Mtpa and 26Mtpa.

“The updated life of mine plan is very good news for Wahgnion, and for Teranga overall,” said Richard Young, President and CEO. “With production averaging about 150,000 ounces of gold per year through 2025 at reasonable costs and at current gold prices, we expect to generate significantly more net cash flow from Wahgnion in the coming years, compared to the original feasibility study.”

Mr. Young added: “The Wahgnion update further demonstrates our team’s exploration, development and operating expertise, which we will leverage at the newly integrated Sabodala-Massawa complex and across our pipeline of early to advanced stage exploration properties in West Africa.”

Year-to-date, total gold recovered in the plant is reconciling well to reserve models following a minor negative reconciliation to reserves in 2019 due to the impact of historic artisanal activities and start-up conditions during plant commissioning. As of December 31, 2019, Wahgnion had a proven and probable reserve base of 1.55 million ounces (30.32 Mt at 1.59 g/t Au at $1,250 gold) and measured and indicated resources of 2.37 million ounces (49.62 Mt at 1.49 g/t Au at $1,500 gold).

“We are extremely pleased with the results of the Wahgnion life of mine plan update, with the confirmation of sustainable higher plant throughput rates and the corresponding increase in production,” said Paul Chawrun, Chief Operating Officer. “We are also confident in Wahgnion’s potential to increase resources and ultimately reserves in the coming years. Our reserve development drill program will focus on Nogbele, Fourkoura and Stinger, which are all near-mill deposits that demonstrate room for expansion, as well as at over a dozen regional prospects that have undergone limited drilling and present further upside.”

Wahgnion’s priority exploration prospects demonstrate favourable lithology and structural characteristics with positive geochemical and geophysical signatures similar to the known deposits comprising the current reserve base.

Updated Wahgnion LOM Mine Plan

The mine plan for Wahgnion focuses on open-pit mining of four initial gold deposits within the mine lease, which includes the Nogbele, Fourkoura, Stinger and Samavogo deposits (see Figure 1 in Appendix).

The Wahgnion processing plant is adjacent to the Nogbele deposit, which contains approximately 50% of total mineral reserves. The Fourkoura, Stinger, and Samavogo deposits are each located within 25 kilometres of the plant.

Operating Costs(2)

Operating costs include all direct costs for the production of gold doré. The estimates are based on annual rates determined in the mining schedule with ore delivery from the Wahgnion pits.

Unit mining costs have increased by approximately 20 cents per tonne, compared to the National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) amended technical report on Wahgnion dated July 31, 2019 (“the Report”). Cost increases are due to the change in the composition of the mobile equipment fleet to accommodate more challenging than expected ground conditions in the oxide zones of the pits, as well as extending contractors to increase the mining rate to accommodate the higher mill throughput. Unit processing costs are marginally lower than those set out in the Report, while general and administrative costs are higher than those in the Report by $1.30 per tonne milled, largely due to additional security costs. Overall, total gold production and recovery rates are in line with the Report. Total capital, including development and sustaining capital, has increased by approximately $30 million due to additional mobile equipment required to move approximately 25% more material annually.

Endnotes

(1) The Company has included non-IFRS measures in this document, including total cash costs, total cash costs per ounce, AISC, and AISC per ounce. The Company believes that these measures, in addition to conventional measures prepared in accordance with IFRS, provide investors an improved ability to evaluate the underlying performance of the Company. The non-IFRS measures are intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. These measures do not have any standardized meaning prescribed under IFRS, and therefore may not be comparable to other issuers. Total cash costs figures are calculated in accordance with a standard developed by The Gold Institute, which was a worldwide association of suppliers of gold and gold products and included leading North American gold producers. The Gold Institute ceased operations in 2002, but the standard is considered the accepted standard of reporting cash cost of production in North America. Adoption of the standard is voluntary and the cost measures presented may not be comparable to other similarly titled measure of other companies. Total cash cost per ounce sold is a common financial performance measure in the gold mining industry but has no standard meaning under IFRS. The Company reports total cash costs on a sales basis. We believe that, in addition to conventional measures prepared in accordance with IFRS, certain investors use this information to evaluate the Company’s performance and ability to generate cash flow. Accordingly, it is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. The measure, along with sales, is considered to be a key indicator of a Company’s ability to generate operating profits and cash flow from its mining operations.

Beginning in the second quarter 2013, we adopted an AISC measure consistent with the guidance issued by the World Gold Council (“WGC”) on June 27, 2013, of which Teranga became a member on November 27, 2018. The Company believes that the use of AISC is helpful to analysts, investors and other stakeholders of the Company in assessing its operating performance, its ability to generate net cash flow from current operations and its overall value. This measure is helpful to governments and local communities in understanding the economics of gold mining. AISC is an extension of existing “cash cost” metrics and incorporate costs related to sustaining production. The WGC definition of AISC seeks to extend the definition of total cash costs by adding corporate general and administrative costs, reclamation and remediation costs (including accretion and amortization), exploration and study costs (capital and expensed), capitalized stripping costs and sustaining capital expenditures and represents the total costs of producing gold from current operations. AISC excludes income tax payments, interest costs, costs related to business acquisitions and items needed to normalize profits. Consequently, this measure is not representative of all of the Company’s cash expenditures. In addition, the calculation of AISC does not include depreciation expense as it does not reflect the impact of expenditures incurred in prior periods. Therefore, it is not indicative of the Company’s overall profitability. Life of mine total cash costs and AISC used in this press release are before cash/non-cash inventory movements, and exclude any allocation of corporate overheads. Other companies may calculate this measure differently.

For more information regarding these measures, please refer to Teranga’s Management’s Discussion and Analysis for the three months ended March 31, 2020 accessible on the Company’s website at www.terangagold.com.

(2) Life of mine assumptions include:

  • Gold price: $1,600 per ounce

  • Heavy fuel oil (HFO): $0.72 per litre

  • Light fuel oil (LFO): $1.04 per litre

  • Euro to USD Exchange Rate: 1.10:1

Please refer to non-IFRS Performance Measures.
