Aura Minerals Completes Feasibility Study for the Borborema Project and Increases Ownership Stake in Borborema Inc. to 100%

ROAD TOWN, British Virgin Islands, Aug. 30, 2023 (GLOBE NEWSWIRE) -- Aura Minerals Inc. (TSX: ORA) (B3: AURA33) (OTCQX: ORAAF) (“Aura” or the “Company”) is pleased to announce the results of the Feasibility Study for the Borborema Project (“Borborema” or the “Project”) located in Rio Grande do Norte, Brazil. Borborema will be an open-pit gold mine with anticipated production of 748,000 ounces (oz) of gold over an initial 11.3-year mine life, with additional production upside. The technical report (the “Technical Report”) titled “Feasibility Study for the Borborema Project, Currais Novos Municipality, Rio Grande do Norte, Brazil”, prepared by Aura will be filed by Aura on SEDAR+ and CVM within 45 days of this press release.

Following the completion of this positive Feasibility Study, Aura anticipates the commencement of full construction with an estimated construction budget of US$188 million. Additionally, the Company is reporting that Dundee Resources Limited, a wholly owned subsidiary of Dundee Corporation (TSX: DC.A), (“Dundee”) has elected to convert its 20% equity interest in Borborema Inc. into a net smelter royalty (the “Royalty”) of 1.50% on the first 1,500,000 oz of gold sold, and 1.00% on the next 500,000 oz of gold. Once the production threshold of 2,000,000 oz of gold has been reached, the Royalty will be terminated. Aura is now the sole shareholder of Borborema Inc., controlling 100% of its shares.

Highlights of the Feasibility Study and the Project:

  • Robust Project Economics: Net present value (“NPV”) of US$182 million and after-tax IRR of 21.9% when using the weighted average consensus gold prices for the projected period of US$1,712 per ounce. At a US$1,900 gold price and considering US$100 million debt, the IRR is 51.9% and NPV of US$262 million.
  • Competitive Costs: Life of Mine (“LOM”) all-in-sustaining costs (“AISC”) on average of $949 oz, including the royalty paid to Dundee (“Dundee Royalties”); if excluded, the AISC would be $923 oz, making it a solid first quartile project among the industry AISC curve. In the first 3 years of complete production, average AISC is $875 per ounce, including the new Dundee Royalties. Excluding such royalties, the average AISC would be $831 oz for such period.
  • CAPEX: Total investment of approximately US$188 million with payback in 3.2 years.
  • Initial Operating Life of 11.3 Years: Weighted average annual gold production is estimated at 65 koz, with an estimated LOM of 11.3 years, based on Mineral Reserves estimated in accordance with National Instrument 43-101, – Standards for Disclosure for Minerals Projects (“NI 43-101”). In the first 3 years of production, weighted average annual production is 83 koz.
  • Strong Reserve Base: The Feasibility Study includes updated Mineral Resource and Reserve estimates under CIM and NI43-101 guidelines for the comprising Probable Reserves of 812,000 oz gold.
  • Substantial Resource Profile with Upside for Future Conversion: Borborema’s Mineral Resources consists of 2,077 koz of Indicated and 393 koz of Inferred. Initial measures have already been undertaken to start obtaining the permits to move the road, and upon its successful relocation, Borborema has potential to convert in Mineral Reserves 1,265 koz of Indicated Mineral Resources (exclusive of the current Mineral Reserves), depending on future set of modifying factors, such as gold price, exchange rate and others.
  • Exploration Potential Remains: The ore body of the Borborema deposit remains open along strike and down dip. Aura believes the project will benefit from additional drilling both to extend the Mineral Resource’s footprint and also to add more contained ounces within the current envelope of mineralization.

Rodrigo Barbosa, President and CEO of Aura, comments, "Borborema is expected to contribute significantly to our overall production profile, and we are delighted to announce this highly accretive Feasibility Study. Our optimism extends beyond the current findings, as a potential additional of 1.265 million ounces are expected to be converted to reserves following the completion of a 5.3 km road relocation besides new resources that should be added in the future once ore body remains opened along strike and down dip. Furthermore, Borborema is poised to set new benchmarks with its important contributions to ESG standards by using treated greywater from the local community, utilizing renewable energy sources, and relying on a robust local labor force."

Mr. Barbosa continues, “We are grateful for Dundee’s technical insights in getting us to this stage. Both of our teams worked hard together and both companies will benefit as we advance this project to construction and production by early 2025.”

Borborema Project Overview

The Borborema Project, located in the southern portion of the state of Rio Grande do Norte in north‐eastern Brazil, is situated 26 km east of the well‐established town of Currais Novos and 35 km west of the town of Santa Cruz. The town of Currais Novos has good infrastructure and a population of approximately 45,000 people. The Project site is strategically located to benefit from direct access to the BR‐226 federal highway linking it to the state capital Natal which lies 172 km east and has a population of approximately 880,000 inhabitants.

Geology, Mineralization and Drilling

The deposit at the Borborema Project is considered to be a classic mesothermal/orogenic gold deposit type in a sheared and deformed Archaean to Proterozoic greenstone belt sequence comprised of metamorphosed volcanic‐sedimentary rocks units intruded by slightly younger post‐tectonic igneous bodies.

The Borborema deposit is hosted within a sequence of banded arkosic metapelitic schists, subjected to upper‐amphibolite facies regional metamorphism.

The mineralization types are strongly controlled by regional structure with secondary structures providing the preferred host for gold mineralization. In addition to the main mineralized zone, several thinner sub-parallel zones with gold mineralization are identified. Two distinct gold mineralization types are identified in drill cores: 1) disseminated free gold, and 2) gold in association with sulphide mineralization represented by pyrrhotite, chalcopyrite, pyrite, sphalerite, and galena. Additionally, the sulphide mineralization was observed in the outer contact between chert boudins and schist along with or associated with schist foliation.

The main Borborema ore body has overall dimensions of approximately 600 meters in the down-dip direction, 3,500 meters along the strike, and averages of 50 meters in thickness in the central and 30 meters in thickness in the southern and northern portions. The Borborema deposit is located within a NE-SW trending shear zone and displays a penetrative NNE‐trending fabric, dipping southeast at around 40 degrees. The ore body is open down dip beyond current Inferred Mineral Resources.

The Borborema deposit has been drilled out at nominal drill spacing of approximately 50m x 50m. A total of 303 diamond drill holes and 921 reverse circulation (“RC”) holes totaling 109,090m were drilled between 1979 and 2022. The property drilling database contains 74,038 sample intervals within the drilling database used in support of mineral resources.

Historical drilling at Borborema has been completed in various campaigns since 1979 by several companies including Itaperiba, Xapetuba, JICA, Santa Elina, and Caraíba. Crusader began drilling at the Project in August 2010 and drilled consistently until the end of 2012. Big River drilled 13 holes to extend known mineralization at depth and increase inferred mineral resources. Aura Minerals has not conducted any drilling on the Borborema property.

Data Verification

SRK Consulting (U.S.), Inc. (“SRK”) performed data verification and validation procedures on the drilling database prior to modeling and estimation. SRK reviewed the geological, drilling, and Au analytical data which was used to support Mineral Resources. Additionally, QP of Resources conducted a site visit to the Project reviewing pit geology, drill core, sample storage and security, as well conducting interviews with site personnel. It is the QP’s opinion that the raw drilling data used for estimating Mineral Resources have been adequately reviewed and any identified potential risks are accounted for in resource classified, in-line with CIM guidelines.

Mineral Resource and Mineral Reserve Estimates

The updated resource block model gold grade was modelled by SRK using Ordinary Kriging (OK) methodology constrained within nested grade shells at 0.2 g/t, 0.5 g/t, and 1.0 g/t indicatory grade shells.

SRK used a nested, soft-boundary grade shell technique with shells at 0.2, 0.5, and 1.0 g/t Au to limit the influence of variable Au grades in the broader mineralized volume which displays general lower grade attributes. Raw drilling data was composted to 2 m lengths with upper capping applied at 20 g/t Au. Kriging neighborhoods and variography were determined for each nested grade shell. The Feasibility Study block model showed acceptable validation against composited and raw data with acceptable smoothing and is considered suitable for use in reporting of Mineral Resources.

SRK utilized an oxidation boundary surface constructed in 2012 by Crusader (Cascar) to discriminate oxide from sulfide mineralization as the logging data was considered too variable and of lower confidence to construct this surface. The oxidation model is utilized to code bulk density as well.

Mineral Resources are classified in accordance with NI 43-101 and CIM definitions into Indicated and Inferred categories based on identified uncertainly and risks.

In order to establish reasonable prospects for eventual economic extraction (RPEEE) as per NI 43-101 definitions of Mineral Resources, SRK applied an economic cut-off grade (CoG) to blocks constrained within an economic pit shell on the Borborema property. This shell utilizes a 1.0 revenue factor, 37-degree slope on the west and 60-degree slope on the east, 2 million tonnes per annum (Mtpa) mining rate, and 5% discount rate. A long section of the resource pit shell is shown in figure below.

The Feasibility Study includes Mineral Resource and Reserve estimates for the Borborema deposit under CIM guidelines. Only Indicated Mineral Resources was considered for purpose of the Feasibility Study. A summary of the Borborema Mineral Resources estimates which are used in the Feasibility Study and expected to be included in the Feasibility Study are shown in table below.

Mine Plan

At Borborema, the ore is near surface and continues at depth. The initial 11 years and 4 months are planned for open pit mining, with operations based on the use of hydraulic excavators and a haul truck fleet engaged in conventional open pit mining techniques. The open pit mining activities were assumed to be primarily undertaken by a contractor-operated fleet.

The stripping ratio is 3.8:1 waste to ore, and 7.2 Mt of pre-stripping is proposed. The mine production schedule delivers 22.5 Mt of ore grading 1.12 g/t gold to the mill over the LOM. Waste tonnage totaling 84.5 Mt will be placed in the waste rock dumps.

Mining costs, including the mining contractor charges, stockpile re-handling and grade control, are estimated to average US$2.78/t mined over the LOM.

Production Schedule

Two low-grade stockpiles are envisaged for the Project to improve grades for the initial years and control the rate of oxide ore on the plant feed. Low grade ore will be stockpiled during the operation and reclaimed at the end of the LOM or when required. The oxide stockpile is also planned to control the maximum rate of oxide material that can be fed to the plant.

The LOM plan shows recoveries of 92.1% with a weighted average production of 83 koz of gold per year for the first three years (2025-2027) with a weighted average AISC of US$875/oz. LOM weighted average production of 65 koz of gold per year with LOM weighted average AISC of US$949/oz.


The Project includes a process plant capable of treating 2 Mtpa of ore through single-stage primary crushing, grinding semi-autogenous grinding mill in a closed circuit with hydrocyclones, gravimetry and intensive leaching, carbon-in-leach tanks, elution, thickening unit, detox and final thickening unit for tailings filtering.

Processing costs are estimated to average US$12.31/t of ore processed over the LOM. The three largest cost components are power, grinding media, and cyanide. Other significant costs are workforce, carbon, and maintenance materials.


The process considers the average G&A costs of US$5.01/t over the LOM. This workforce mainly includes management, health, safety and environmental, administration, human resources, IT, law enforcement, procurement, royalties, insurance, etc.

Taxes and Royalties

The financial model incorporates assumptions about the income tax reduction benefit made available under a government regulation. The income tax rate is calculated at 17.58%. The Project will pay royalties of 1.5% of gross revenue to the Federal, State and Local Governments (CFEM).

The Project will also pay royalties equivalent to 1.50% on the sale of any product containing economically recoverable minerals obtained from ore mined and removed from the mine to Dundee Resources Limited. The 1.50% net smelter return applies to the first 1,500,000 ounces of gold sold, then is reduced to 1.00% on the next 500,000 ounces of gold. Once the production threshold of 2,000,000 ounces of gold from the Borborema gold project has been reached, the Royalty will terminate in accordance with its terms.

Engineering, Procurement and Construction Management

Basic engineering and detailed engineering for earthmoving are completed, and engineering design for the mine is completed. Plant detailed engineering is set to begin. Aura commenced early works construction for Borborema in Q2 2023 and vegetation suppression 48% complete, plant site is almost cleared and leveled, and the longest lead-time equipment (mill) has been ordered. Of the US$188 million construction budget, US$1.1 million has been spent as of Q2 2023 and US$11.4 million is planned for the second half of 2023.

Caution Regarding Mineral Resource and Mineral Reserve Estimates

The figures for mineral resources and reserves contained herein are estimates only and no assurance can be given that the anticipated tonnages and grades will be achieved, that the indicated level of recovery will be realized or that the mineral resources and reserves could be mined or processed profitably. Actual reserves, if any, may not conform to geological, metallurgical or other expectations, and the volume and grade of ore recovered may be below the estimated levels. There are numerous uncertainties inherent in estimating mineral resources and reserves, including many factors beyond the Company’s control. Such estimation is a subjective process, and the accuracy of any reserve or resource estimate is a function of the quantity and quality of available data and of the assumptions made and judgments used in engineering and geological interpretation. Short-term operating factors relating to the mineral resources and reserves, such as the need for orderly development of the ore bodies or the processing of new or different ore grades, may cause the mining operation to be unprofitable in any particular accounting period. In addition, there can be no assurance that metal recoveries in small scale laboratory tests will be duplicated in larger scale tests under on-site conditions or during production. Lower market prices, increased production costs, the presence of deleterious elements, reduced recovery rates and other factors may result in revision of its resource and reserve estimates from time to time or may render the Company’s resources and reserves uneconomic to exploit. Resource and reserve data is not indicative of future results of operations. If the Company’s actual mineral resources and reserves are less than current estimates or if the Company fails to develop its resource base through the realization of identified mineralized potential, its results of operations or financial condition may be materially and adversely affected.

All forward-looking statements herein are qualified by this cautionary statement. Accordingly, readers should not place undue reliance on forward-looking statements. The Company undertakes no obligation to update publicly or otherwise revise any forward-looking statements whether as a result of new information or future events or otherwise, except as may be required by law. If the Company does update one or more forward-looking statements, no inference should be drawn that it will make additional updates with respect to those or other forward-looking statements.

Forward-Looking Information

This press release contains “forward-looking information” and “forward-looking statements”, as defined in applicable securities laws (collectively, “forward-looking statements”) which include, without limitation, mineral resources and mineral reserve estimates and the economic analysis resulting from the Feasibility Study (including NPV, IRR and payback periods); expected production from, and the further potential of the Company’s properties; the ability of the Company to achieve its longer-term outlook; the amount of future production over any period and LOM, capital expenditure, AISC and mine production costs, the Company’s target leverage ratio for the Project; and the completion of the conversion of Dundee’s equity interest in the Project into a net smelter returns royalty.

Known and unknown risks, uncertainties and other factors, many of which are beyond the Company’s ability to predict or control, could cause actual results to differ materially from those contained in the forward-looking statements if such risks, uncertainties or factors materialize. The Company has made numerous assumptions with respect to forward-looking information contain herein, including among other things, assumptions from the Feasibility Study, which may include assumptions on gold prices and exchange rates, which could also cause actual results to differ materially from those contained in the forward-looking statements if such assumptions prove wrong. Specific reference is made to the Company’s most recent AIF on file with certain Canadian provincial securities regulatory authorities and the Technical Reports for a discussion of some of the risk factors underlying forward-looking statements, which include, without limitation the ability of the Company to achieve its longer-term outlook and the anticipated timing and results thereof, the ability to lower costs and increase production, the ability of the Company to successfully achieve business objectives, copper and gold or certain other commodity price volatility, changes in debt and equity markets, the uncertainties involved in interpreting geological data, increases in costs, environmental compliance and changes in environmental legislation and regulation, interest rate and exchange rate fluctuations, general economic conditions and other risks involved in the mineral exploration and development industry.
