Big River Gold Ltd Receives Assay Results for an Additional 5 Drillholes of the Resource Extension Drilling Program at the Borborema Gold Project in North East Brazil Big River Gold Ltd. announced that assay results have been received for an additional 5 drillholes of the resource extension drilling program at the Borborema Gold project in north east Brazil. Drillhole details for these 5 holes along with summaries of assay results returned. Drill holes CRD182 to CRDD185 are in close proximity to section 20,000mN along which several high grade intercepts were reported to the ASX on 12 April, 2012 and 6 June, 2012. The details drill holes CRDD 138 which intersected 50m at 4.95g/t Au (including 27m at 8.49 g/t Au) and CRDD134 which intersected 47m at 2.31 g/t Au (including 15m at 3.61 g/t Au). These holes are located approximately 70m from hole CRDD184 (33m at 4.27 g/t Au) which confirms the potential for defining a higher-grade feeder zone or core to the resource and warrants additional follow up drilling. Assay results were received for an additional 5 of the extension drillholes completed at Borborema. Assay results from 2 holes are awaited. Highlights of these drillholes include: CRDD-184 intersected 33m at 4.27 g/t Au (including 8m at 11.12 g/t Au and 6m at 4.64 g/t Au); CRDD-185 intersected 41m at 1.58 g/t Au (including 10m at 2.21 g/t Au and 3m at 7.69 g/t Au) and, CRDD-182 intersected 44m at 1.38 g/t Au (including 7m at 2.45 g/t Au). All holes have now been completed for the first stage of the resource extension drilling program. All holes intercepted elevated grades in projected zones of mineralisation at 100m down dip to the resource and along 1.2km of strike. Drilling the central zone has confirmed thick zones of significantly high grades over 300m of strike extending below the depth of previous drilling. It further indicates the potential to define high grade feeder zones to the Borborema project. Elevated grades encountered in holes CRDD182-185 are in close proximity to previously reported drillholes CRDD138 and CRDD134 that intercepted 50m at 4.95g/t Au and 47m at 2.31g/t Au respectively.

Big River Gold Limited Recommences Borborema Resource Extension Drilling Big River Gold Limited announced that drilling is underway at the Borborema Gold Project to test depth and high grade shoot extensions which can be incorporated into mine planning for expanded production scenarios. Big River's objective is to better define the width and grade of the resource at depth for improved mine planning and investigation of expanded production scenarios for the Borborema project. In addition there are significant previously reported high grade intercepts that appear part of a southerly plunging shoot development and warrant follow up. These intercepts include 50m at 4.95g/t Au (CRDD-138) and 47m at 2.31 g/t Au (incl 15m at 3.61g/t Au) in CRDD -134. Big River has planned approximately 5,000 meters in the first stage diamond drilling program initially targeting the high grade down plunge and below pit extensions. This comprises: Step out drilling 100m down plunge from prior intercepts will test continuous higher-grade zones. Pit optimisation work is limited to the current drilling and Big River is confident this current drilling will identify and extend mineralisation down dip >100m over 1.2km strike, and Additional infill drilling will be planned once this initial stage is completed.

Big River Gold Ltd Provides Update on its Project Developments Big River Gold Ltd. announced progress in advancing the Borborema Gold Project and exploration in the surrounding area. Despite the impact of COVID-19, travel to the Borborema Project site is still possible with appropriate precautions and activities are still being undertaken on behalf of Big River by various engineering groups. The project timeline is not expected to be materially impacted. The main areas of activity include: Option study of comminution circuits to facilitate a possible future expansion. Early commencement of water catchment construction. Securing additional water supply. Power line design and consideration of possible future capacity requirements. Establishing an Owners Team to implement project construction. Preparing exploration programs targeting high grade mineralisation in and around the planned pits. Plans to secure project finance will resume following the end of year break and required due diligence will accommodate the results of the plant option review. Project Progress: Plant design option review planning for the future: The mine plan as outlined in the July 2020 Definitive Feasibility Study (DFS) is to commence with a processing plant designed with a throughput of 2 million tonnes per annum (Mtpa) and anticipates a future expansion to a throughput of up to 4Mtpa. Any future expansion will be subject to ongoing economic and technical studies and the availability of sufficient process water. However, the BGP currently holds permits for a 4Mtpa operation and it is the Boards view that an expansion up to that level would be a better match for a project that comprises 42.4Mt reserves containing 1.61M oz gold. That reserve figure excludes any of the 17Mt contained within the inferred resource category. The option review seeks to ensure that the current DFS plant design is best suited for any anticipated expansion without incurring excessive capital costs or disruption to production that could be prevented by improved planning and provisions now. Importantly the essential process path will not change but certain equipment choices and/or layout may be refined. This process is being undertaken by Wave International Ltd. using previously quoted costs. It is anticipated that the initial phase will take only a few weeks although additional time may be required to bring any revisions up to the necessary level of accuracy during the first quarter of 2021. The appointment of an EPCM contractor for project implementation will be finalised subsequent to the review. Water catchment construction fast tracked: Construction of the water dyke and catchment will commence earlier than previously anticipated to take advantage of any rainfall that may occur before the mine is commissioned. Engineering groups have quoted to complete detailed design following geotechnical and other ground assessment. Construction of the water dam should be completed in the third quarter of 2021. Securing additional process (sewage) water: The current DFS plant design of 2Mtpa is underpinned by the sewage water offtake contract supplying 70m3/hr that was finalised with the Currais Novos Water Authority (CAERN). Big River is actively looking to secure additional supplies from several sources. Options include increasing the size of the offtake agreement with CAERN and a formal request to increase that supply was submitted by Big River in January 2021. In the meantime, upgrades to the greywater collection system at Currais Novos have been undertaken in and around the Caça e Pesca treated effluent pumping station. Exploration Re-activated: With additional funding, exploration programs in the tenements around and along strike of the BGP are being re-activated, subject to appropriate Covid19 restrictions and safety precautions. In addition, planning has commenced to test previously undrilled high-grade zones adjacent to the reserve and pit designs as well as attempt to upgrade part of the 560,000 oz gold Inferred resource immediately below the reserve to Indicated status. Mica Testwork & Marketing Study: Testwork on producing a saleable mica concentrate from the Borborema plant tailings was completed during December. This included tests on plasticity and compounding characteristics which were conducted in the UK due to COVID-19 constraints in Melbourne. Annuncio • Dec 30

Big River Gold Ltd Announces Significant Stage of the Analysis Being Undertaken to Assess the Commercial Viability of Mica Production at its 100% Owned Borborema Gold Project Big River Gold Ltd. announced that a significant stage of the analysis being undertaken to assess the commercial viability of mica production at the Company's 100% owned Borborema Gold project, has been completed by Nagrom in Perth, WA with positive results. The program currently being undertaken by Nagrom follows on from the testwork completed successfully by Dorfner Analysenzentrum und Anlagenplanung Gmbh (ANZAPLAN in Germany). The aim of Nagrom's work is to produce a commercially viable bulk concentrate in the first instance of which details of the chemical and physical properties can be made available to potential distributers or other offtake counterparties. The Borborema ore body contains very significant quantities of auriferous mica that will be processed through its planned 2Mtpa CIP process plant1. Initial work showed that after processing through the milling, cyanide leach and elution circuits, a substantial amount of mica could be readily separated by magnetic separation. This product retained attractive commercial chemical and physical properties including flake size and importantly, being free of deleterious crystalline silica (quartz). Magnetic separation represents a technically simple, low cost and chemical free process that could be readily included or retro-fitted to the currently designed gold plant to process the dry tails. Potential applications for this type of product are in the large volume plastic filler market, (in particular dark coloured polymers). Other uses could be for coatings and in the paint market where it would serve as a key additive with anti-corrosive properties. The 2018 pricing for a wet ground fine mica concentrate of this type from the USA was USD 300 USD 500 per tonne. All of the work in Nagroms scope was completed in August. Additional testwork investigating the physical and plasticity characteristics is being completed by Microanalysis Ltd. in Perth after some delays in receiving the samples due to Covid19 restrictions. A Technical data Sheet (TDS) will be made available for the market at that time. Annuncio • Sep 17
Big River Gold Ltd Provides Update to Shareholders Big River Gold Ltd. announced the shareholders of the Company's recent activities primarily in relation to project funding for the Borborema Gold Project, progress of the mica testwork and receipt of Posse progress payments. On-site activities continued to be adversely impacted by COVID-19 restrictions during 2020. However, negotiations regarding the sourcing of project funding is continuing along with range of other activities that can be performed from abroad as well as within Brazil. The Company expects that mobilisation of construction teams to site will be possible in early 2021 when the coronavirus restrictions are expected to be relaxed sufficiently to allow freer movement of personnel and equipment. Consequently, Big River has sought expressions of interest (EOI) from EPCM contractors who could undertake detailed engineering design, establish project teams and identify long lead-time capital items. This work will be funded with existing cash reserves and other project financing. Project Funding - Engagement of Auramet International: Big River has engaged Auramet International LLC (Auramet) to assist with securing the debt funding component of the Borborema project finance. Project Progress: Appointment of EPCM contractors: In anticipation of securing project funding and to continue development momentum, Big River has advanced the process leading to appointment of the EPCM contractor for project implementation. Other activities: Work continued on progressing other Borborema planning and site works. Environmental: Discussions and planning with IDEMA (Environment Agency of Rio Grande do Norte State) continued in relation to the licensing of the road access and the installation of the sewage treatment plant and pipeline. IDEMA also renewed the Operating Licence for the Borborema plant which is testament to the Company's performance on site to date. COSERN (Electric Power Agency of Rio Grande do Norte State): The Company has continued to work with the COSERN team via virtual meetings and progressed all necessary measures including the application for Federal Electric Power Agency authorizations which imminent return is anticipated. The Cascar Brazil team is also progressing the final design layout of the power line with COSERN and the agency's consent. DNIT (Federal Roads Agency): The Company presented DNIT with the designs for the construction of the 30 km greywater pipeline and access to be built alongside Highway 226 from Currais Novos to the Borborema project. DNIT requested further information which was provided and the Company expects to receive the authorizations and permissions in the next few months. Mica Testwork: Testwork on producing a saleable mica concentrate from the Borborema plant tailings progressed well. Aspects that could be actioned from abroad were completed during August. The remaining tests on plasticity and compounding characteristics were delayed as these works were being conducted from Melbourne which was forcibly shut due to COVID-19 and samples had to be retrieved and sent to another facility which has a more limited capacity to complete the tests which are currently being undertaken. In summary, the results achieved by Nagrom during August were very encouraging: A final grade mica concentrate was achieved that is equivalent or slightly better than that produced by ANZAPLAN and by removing the desliming stage provides a 25% better mass yield. The Nagrom magnetic separation circuit is much less complex than was previously proposed with only 3 stages of magnetic separation required in Nagrom's program compared to the 6 stages in the ANZAPLAN flowsheet. The reduction in the number of stages will result in improved capital and operating costs. Nagrom have demonstrated that the use of conventional fine grinding equipment is able to produce a product that is similar to that sold into the plastic and polymer markets. Overall the results have continued the positive trend of previous testwork and identified further improvements in product quality and costs. At present the plan is to take the simplest route and produce a bulk concentrate that will target the plastic filler market. Sample results will be made available to prospective purchasers in the next few weeks. Posse Sale Receipts: The final instalment has been received which concludes the sale of the Posse iron mine in 2017. A total of AUD 920,000 was received in several instalments that commenced in April 2020.
