  • Third quarter gold production of 10,187 ounces of gold, resulting in total production for the year to date of approximately 30,000 ounces, an eleven per cent improvement over the same period in 2018.
  • Total ore mined for the quarter of 44,757 tonnes at 7.14 grams per tonne (“g/t”) of gold. 
  • 45,378 tonnes of run of mine (“ROM”) ore were processed through the plant from the combined Palito and Sao Chico orebodies, with an average grade of 6.84 g/t of gold.    
  • 2,433 metres of horizontal development completed during the quarter.
  • The Company anticipates full year production for 2019 will be between 40,000 and 41,000 ounces.
  • Completion of the Company’s Preliminary Economic Assessment (“PEA”) on the Coringa Gold Project in September, demonstrating strong positive economics.

Mike Hodgson, CEO, commented:

“We are delighted to report our third quarter production of 10,187 ounces of gold, which is another excellent performance and as a result the Company is very well placed to exceed 40,000 ounces of gold production for 2019 and significantly improve on the 2018 gold production of 37,108 ounces.   

“Mining and plant throughput rates and grades showed modest improvements compared to the second quarter.  As reported last quarter, being plant constrained, we focus strongly on the quality of the ore feed and maximising plant availability.  As a result, the plant has now processed 132,540 tonnes year to date, which represents an eight per cent improvement over the same nine month period in 2018.  The processing circuit for treatment of stockpiled gold bearing flotation tailings continued to perform well, and for the last five months processing rates have averaged over 100 tonnes per day with a total of 20,554 tonnes of an average grade of 4.13 g/t of gold having been processed during the year to date.  With a considerable stock of this tailings material remaining, we expect to continue processing these stockpiles to supplement run of mine gold production beyond the year end.        

“The quarter also saw the much anticipated delivery of our ore sorter.  The accompanying infrastructure is close to completion and we hope to start commissioning before the year end and with the expected benefits starting to be seen in the early part of 2020.  Its introduction will provide benefit by creating much needed space in the process plant in turn allowing for more flexibility to improve maintenance scheduling whilst also, through the liberation of process capacity, providing the opportunity to increase gold production in 2020. 

“Development and production from the Palito orebody followed the same pattern as the second quarter, with development focusing on the veins of Pipocas, Mogno and Ipe veins.  The latter two veins are narrower than most Palito veins but exhibit at times exceptionally high grades.  We are mining these veins on the 144mRL and above, some 200 vertical metres above the deepest levels in the mine, and therefore can continue to provide run of mine without any requirement for further deepening of the mine.

“At the Sao Chico orebody, development continues on the deepest level, -48mRL, with lateral development being undertaken to the west in the upper level of +186mRL.  During the quarter we contracted a surface drilling contractor to undertake step out drilling east and west of the Sao Chico orebody to follow up on the results of the last drilling campaign undertaken during 2018.  The intention of this new campaign is to drill the immediate strike extensions beyond the current mine limits, with subsequent step outs.  After this initial work, the rigs will be assigned to test the near-minesite geophysical anomalies of Abelha, Besouro, Cicada and Cinderella, all of which lie within a 10 kilometre radius of Sao Chico.

“We are very excited about the prospectivity of these anomalies. They each exhibit geophysical signatures substantially better than anything else we have encountered around the Sao Chico deposit, and all have been the subject of significant artisanal mining activity, suggesting that the conductive body that we have identified has good potential to be gold bearing.

“The most significant news of the quarter was the release of the results of the Preliminary Economic Assessment (“PEA”) at Coringa.  The highlights of the study are reproduced below, but in summary the results were very positive, indicating annual gold production, after an initial ramp-up period, averaging approximately 38,000 ounces per annum, a mine life of approximately nine years, average gold grades of 8.3 g/t, an AISC of approximately US$852 per ounces and an initial capex estimate of US$25 million.  The costs and capital each include a 20 per cent contingency, so I feel confident that we can improve on these cost estimates. 

“We are continuing to work very hard on the outstanding permitting requirements.  The amended Environmental Impact Assessment (EIA) for Coringa, revised to replace the original plan for a conventional tailings management facility with dry tailings technology (a filtration plant allowing for the dry stacking of tails), was submitted to the authorities two weeks ago.  It was our decision to make this resubmission as the original EIA had already been approved by the state environmental agency, SEMAS, in late 2018. Whilst we are now awaiting approval from SEMAS again, they have welcomed our decision to revise the tailings management solution and we expect swift approval of the amendment.  This will allow us to proceed with the necessary public hearings and we hope to be in receipt of the Preliminary Licence (“Licencia Previa”) by the year end, or early in the first quarter of 2020 at worst.      

“With 30,000 ounces of gold produced for the year to date, the Company is well on course to achieving its best ever annual level of production.  With mine production in good order and the additional ounces the tailings treatment is now bringing, I fully expect a good final quarter.  Gold prices remain strong, and even stronger in Brazilian Reals.  Following the issuing of a positive PEA and the resubmission of the EIA, we now hope we can progress Coringa permitting rapidly and see real progress on the ground at site next year.  I look forward to reporting further positive news in the coming months.”

Production Results

Total production for the third quarter of 2019 was 10,187 ounces of gold, generated from the processing of 45,378 tonnes of ore at overall average grades of 6.84 g/t of gold. This processed ore was sourced from hard rock mined ore from the Palito and Sao Chico orebodies, supplemented by the processing of 9,662 tonnes of surface stockpiled flotation tailings grading approximately 3.97 g/t gold.  Mined tonnage for the quarter totalled 44,757 tonnes with a grade of 7.14 g/t of gold.   

On 30 September 2019, there were coarse ore stocks of approximately 2,600 tonnes of ore with an average grade of 8.50 g/t of gold, and significant stockpile of flotation tails with an estimated average grade of 3.00 g/t of gold. These stockpiles are being slowly consumed, used as a ‘top-up’ to mined ROM to keep the plant full.  The stockpile of flotation tailings is considered to be sufficient to continue to process this material at current rates for a significant part of 2020.

A total of 2,433 metres of horizontal development has been completed during the quarter, of which 967 metres was ore development.  The balance is the ramp, cross cuts and stope preparation development. 

2019 Production Guidance

The Company anticipates full year production for 2019 will be between 40,000 and 41,000 ounces.
