ValOre Provides Update on Rhodium Assay Program at Pedra Branca PGE Project
May 6, 2021
All targets and deposits return rhodium mineralization, highlights of 1.44 and 1.37 g/t Rh from Esbarro deposit, 1.27 g/t Rh from Cedro deposit
Vancouver, B.C. ValOre Metals Corp. (“ValOre”; TSX-V: VO; OTC: KVLQF; Frankfurt: KEQ0, “the Company”) today provided an update on the rhodium (“Rh”) assay program of historical and 2020 drill core samples (“samples” being pulps, pulverized rejects and coarse rejects of historical core) from ValOre’s 100%-owned Pedra Branca Platinum Group Element (“PGE”) Project in northeastern Brazil.
“The potential of rhodium as a significant value driver at Pedra Branca had not been assessed prior to ValOre,” stated Colin Smith, Vice President of Exploration. “After four phases of rhodium assaying in 2020 and 2021, we have firmly established the presence of significant district-wide rhodium mineralization in all five currently delineated PGE deposits and both selected pre-resource targets.”
Rhodium Assay Program Highlights:
- ValOre has conducted four phases of Rh assay programs to date
- 1,069 samples from 154 drill holes (125 historical holes, 29 holes from 2020)
- All five deposits with NI 43-101 defined resource estimates, as well as two 2020 drill targets;
- All deposits and targets returned Rh assays, establishing that Rh mineralization is present throughout the Pedra Branca PGE district;
- Highlight assays of 1.44 grams per tonne rhodium (“g/t Rh”) over 0.50 metres (“m”) and 1.37 g/t Rh over 0.50 m from the Esbarro deposit, 1.27 g/t Rh over 0.97 m from the Cedro deposit, and an average of 0.07 g/t Rh in samples with detectable Rh;
- >40% (432) of samples assayed to date have returned Rh assay results (≥0.01 g/t Rh);
- A strong positive correlation between palladium + platinum + gold (“2PGE+Au”) grade and Rh grade is observed, with 78% of samples with 2PGE+Au grades >5 g/t returning anomalous Rh;
- Rh mineralization is shallow in nature, with the average Rh-bearing sample starting at 54 m drill hole depth.
ValOre has completed four Rh assay programs to date, totaling 1,069 assayed samples from 154 drill holes (125 historical holes and 29 holes from ValOre’s 2020 drill campaigns). The fourth phase of Rh assaying comprised 786 samples selected on the basis of historical and 2020 core assay 2PGE+Au grade thresholds of ≥1 g/t and was initiated based on the strong Rh assay results from the three previous Rh programs conducted by ValOre in 2020 and 2021 (see news releases dated March 12, 2020, November 19, 2020 and March 2, 2021).
All five PGE deposits having NI 43-101 defined resource estimates and two pre-resource 2020 drill targets were examined and confirmed to host Rh mineralization. Prior to ValOre’s involvement in the Pedra Branca PGE Project, no drill core samples had been historically assayed for Rh, and ValOre’s positive results to date demonstrate Pedra Branca as a 3PGE+Au district. A strong positive correlation between 2PGE+Au grade and Rh grade is further corroborated, with 78% of samples with 2PGE+Au grades of ≥5 g/t producing anomalous Rh. Rhodium mineralization established to date is situated near-surface, with an average Rh-bearing sample interval depth starting at 54 m drill hole depth.
The C-04 target, which generated a drilling discovery in 2020 (see news release dated October 27, 2020), and the pre-resource Cana Brava target (three shallow PGE drill intercepts in four 2020 drill holes), exhibited the highest percentage of Rh-mineralized samples, at 70% and 64% of submitted samples. The Cedro, Esbarro and Curiu PGE deposits demonstrated significant Rh potential, with 51%, 50% and 47% of samples assayed returning Rh mineralization. The Trapia and Santo Amaro PGE deposits also returned notable Rh assays in 32% and 13% of submitted samples.

Rhodium is the rarest of the platinum group elements, occurring only up to one part per 200 million in the Earth's crust. The main use for rhodium is in catalytic converters designed to clean vehicle emissions. Due to its brilliance and resistance to oxidation, it is also used as a finish for jewelry, LCD monitors, and mirrors. In the chemical industry it is used in the production of nitric acid, acetic acid and hydrogenation reactions. Rhodium is found in platinum and nickel ores together with the other PGEs. South Africa is the world’s largest producer of rhodium (~80%), followed by Russia (~10%), Zimbabwe (~5%), Canada (~2%) and the U.S.A. (~2%). The global average resource/reserve grade is 0.281 g/t Rh, with the lowest reported resource/reserve grade of 0.010 g/t Rh (Canadian project) and the highest reported resource/reserve grade of 0.381 g/t Rh (South African project) (source: S&P Global).
Quality Control/Quality Assurance (QA/QC)
Historical Pedra Branca drill core samples were collected from ValOre’s secured core logging and storage facility located in Capitão Mór, Ceará, Brazil. A minimum sample weight of 50 g ensured an adequate sample for assay. Selected pulp samples were sent with an ensured chain of custody to SGS Geosol, Vespasiano, Minas Gerais, Brazil for analysis, which is an accredited mineral analysis laboratory. All samples were analyzed for Rh content using standard 50 g Fire Assay Atomic Absorption ICP-MS. Certified PGE ore reference standards, blanks and field duplicates were inserted as a part of ValOre’s quality control/quality assurance program. No QA/QC issues were noted with the results reported herein.

At Pedra Branca, 5 distinct PGE+Au deposit areas host, in aggregate, a current Inferred Resource of 1,067,000 ounces 2PGE+Au contained in 27.2 million tonnes grading 1.22 g/t 2PGE+Au (see ValOre’s July 23, 2019 news release). All the currently known Pedra Branca inferred PGE resources are potentially open pittable.
Comprehensive exploration programs have demonstrated the "District Scale" potential of ValOre’s Angilak Property in Nunavut Territory, Canada that hosts the Lac 50 Trend having a current Inferred Resource of 2,831,000 tonnes grading 0.69% U3O8, totaling 43.3 million pounds U3O8. For disclosure related to the inferred resource for the Lac 50 Trend uranium deposits, please refer to ValOre's news release of March 1, 2013.
ValOre’s team has forged strong relationships with sophisticated resource sector investors and partner Nunavut Tunngavik Inc. (NTI) on both the Angilak and Baffin Gold Properties.
