In 2010, an aerogeophysical survey was carried out, resulting on the generation Magnetometric (Analytical Signal, Total Field) and Gamma-spectrometric (Total Count and Channels of K, Th and U) maps, totaling 4,223 km of survey lines, covering a 778 km2.

In the sequence of the exploration activities, Rare Earths’ exploration areas have been claimed, later divided into the following targets: Nova Esperança, Ema, Centro Norte, Montividiu and Ribeirão Grande. Detailed work were initiated by Alvo Nova Esperança, sampling stream sediments, PAN concentrates, soil and rock, followed by terrestrial geophysics. In the second half of 2011, the first survey campaign started at the New Hope Grid (Grid Nova Esperança) and was finalized at the beginning of 2012. A further diamond drilling campaign was started, all drill holes with HQ diameter.




The SVPM areas consist of 75 mineral rights, covering an area of 70,363 hectares, comprising 5 municipalities in the northern portion of the state of Goiás (GO) and two counties in the southern state of Tocantins (TO): Minaçu-GO, Trombas-GO, Montividiu do Norte-GO, Palmeirópolis-TO and Jaú do Tocantins-TO.




Rare Earths occur associated in saprolites of Serra Dourada granite, which is the largest intrusion of the Goiás Tin Province. It occupies the axial zone of a Brachianticlinal bound by rocks of the Serra da Mesa Group and has an area of approximately 450 km2 (Marini et al. ., 1976). The intrusion is elongated and oriented according to regional structures, is approximately 64 km long in the NS direction and varies between 3.5 and 12 km wide (mean 7.5 km) in the EW direction.

The type of deposit found in the Pela Ema is that of Rare Earths adsorbed on clays, very similar to what is found in lateritic granite coasts of southeastern China. The enrichment of Rare Earths occurs during the laterization process of these granites, which results in the generation of exchangeable ions of REE, besides a residual source of REE minerals contained in the colluvium and saprolite. This type of deposit is known as "Rare Earths Deposit in Elution Crusts" (Chi and Tian, 2008) and is also referred as a Rare Earths deposit of the ion-adsorbed type.





In September 2016, Serra Verde Pesquisa e Mineração (SVPM) carried out metallurgical tests over two months at pilot scale to validate the agitated leaching and continuous filtration through pressure filters processes (ALF).

A total of 105 bench tests were performed, establishing the guidelines for the operation of the pilot plant. The pilot plant performed twelve (12) tests in sequence. At the end of the program, the operability of the ALF process was confirmed and a scoping study was completed in December 2016.

A second phase of the metallurgical testing program started in February 2017. Serra Verde Exploration and Mining planned a full process piloting operation for three months, from April 2017 to July 2017, in order to confirm and optimize the scoping study presented in December 2016.

The full pilot scale process consisted of the following steps: ore drying and homogenization, screening, continuous agitated leaching followed by filter press filtration, Rare Earths precipitation as Rare Earths mixed carbonate, carbonate filter filtration and recirculation of the processing solution.

Between May 15, 2017 and July 14, 2017, operating 24 hours a day, 6 days a week, a total of eleven (11) continuous piloting campaigns were performed using the ore mixture of three mine zones, processing tons of tons of ore into Rare Earths concentrate.

Chemical analyzes were performed by the SVPM laboratory team of mass and operational control. The test results provided data for engineering studies, CAPEX, OPEX and capital expenditure and variable costs assessments.




Serra Verde is currently developing the basic engineering of the Serra Verde project.

The company hired to carry out this stage of the project is TETRA TECH, a multinational company specialized in the development and implementation of mining projects.

The project under development has the following features:

• Open pit, with no need to dismantle for ore extraction;
• Process route with equipment conventionally used in the mining industry;
• Plant designed for modular expansion allowing expansion with no significant production impact.

The next step will focus on the elaboration of the detailed engineering and start construction.

SVPM aims to be operational in the fourth quarter of 2021.

Rare Earths

REEs have widespread industrial uses; however, the most valuable REEs are those tied to magnet technologies used in electric vehicles, wind turbines and electronics (Nd, Pr, Dy, Tb). REEs have a number of uses in electric vehicles and wind turbines and the forecasted increase in electrification is expected to translate into higher demand (see Figure 3.6-3.8).

REEs are also used extensively in electronics, including smartphones and tablets (see Figure 3.9). There are 17 REEs in the periodic table, of which 16 are used in smartphones.3 Specifically, neodymium, terbium and dysprosium, give smartphones the power to vibrate. Terbium and dysprosium are also used in in touchscreens to produce the colors of a phone display.

Mineração Serra Verde names Eric Noyrez as Chief Executive Officer





For Immediate Release





Industry veteran and board of director member will lead

Brazilian rare earth project into next phase


Goias State, Brazil -- [5 September, 2018] -- Mineração Serra Verde (MSV), an advanced development stage rare earth project in central Brazil, announced that it has appointed Eric Noyrez to Chief Executive Officer.


Leading Project Milestones

Previously a member of the MSV Board of Directors, Noyrez was instrumental in many of the project’s recent milestones including achieving industrially representative piloting and product acceptance.


“Since joining the team in 2017, my focus has been to deliver the project on time and within budget, while also ensuring we’re producing a strongly sustainable new source of competitive rare earths,” said Noyrez, who previously served in several executive roles at Lynas Corporation Limited. “We’ve achieved our goals to-date but must continue strengthening our team as well as find partners who can help us take the Serra Verde project to the next phase. I’m very excited about what is to come and am looking forward to my new role with MSV.”


Noyrez previously was also tasked with moving the project further toward implementation and oversaw a four-month long evaluation process to select an engineering firm. Currently, he is working to recruit an experienced industrial project development and operations team to continue the project’s progress, in addition to selecting equipment suppliers.


“Construction will start in early-2019, so right now we working to get the right partners in place and have already issued an RFP for suppliers. We are serious about this next phase and, thanks to the continued support of our capital partner Denham Capital, confident the project will soon be brought into production,” added Noyrez.



The Serra Verde Deposit

Located in the State of Goias, an established mining region, Serra Verde hosts an NI 43-101-compliant resource of 911 million tonnes @ 0.12 percent TREO (based on an exploration area representing approximately 15 percent of the overall Serra Verde deposit area), with high-value critical and heavy rare earths representing more than 60 percent of the resource. 


Serra Verde’s ionic clay mineralogy is analogous to the mineralogy currently detained by market-dominating southern China producers, but with rare earth grades three times higher than the average of those deposits, and ore volume 10 times larger. The Serra Verde deposit also benefits from access to roads, water and power within 40 kilometers of the site, plus community support.


The region’s high-value rare earth mix is consistent with projected demand growth from next-generation applications ranging from clean energy and hybrid vehicles to high-performance consumer electronics, industrial and military applications.  


In 2017, samples tested were approved as market compliant at all major Rare Earth separators, receiving positive feedback from industry leaders. The project is currently preparing for the engineering phase and is expected to start commercial operations in 2020.


About Serra Verde

Mineração Serra Verde is an advanced development stage rare earth project located near Brasilia, in the State of Goias, a mining friendly jurisdiction. The size of the resource and the project’s ionic clay geology and freely liberated mineralization is similar in geology to the well-known heavy rare earth Chinese deposits.  The weathered rock, saprolite ore allows for open pit, truck-and-shovel extraction -- providing for cheaper, simpler processing and lower capex versus peers.  Further, a large portion of the deposit is comprised of heavy and critical rare earths, which have a higher value as compared to light rare earths, giving the project the potential to challenge China's dominance of the heavy and critical rare earth market.

Business environment gets more favorable – 2018

Business environment gets more favorable

The federal government, with the edition of decrees, beyond change in distribution of Financial Compensation for the Exploration of Mineral Resources (CFEM), brought new standards as a determination to close mines after exploration. The standards were well evaluated by the market because they are close to those practiced internationally and by leaving the environment more favorable to the business.

For Luciano de Freitas Borges, the executive vice president of Serra Verde (with the Rare Earth project in Minaçu), there are improvements in parameters and rules that are easy to apply and will help the sector.
