Aclara Resources Inc. announced the maiden mineral resource estimate (MRE) for its regolith-hosted ion adsorption clay project located in the State of Goias, Brazil, known as the Carina Module. Sampling, Assay & QA/QC Protocols: The 201 auger drill holes were sampled at intervals of 0.5 metres to 2 metres, for a total of 1,418 samples. The analytical batches included 233 QA/QC samples.

All samples were sent for total REE analysis (REY T) to the ALS Laboratory in Lima, Peru, and desorption (REY D) analysis to AGS Laboratory in La Serena, Chile. The methodology for collecting the auger drill samples was designed following recommendations by expert mining industry groups GeoAnsata and GE21. The quality of the assay data for the rare earth elements dysprosium (Dy), neodymium (Nd), praseodymium (Pr) and terbium (Tb) was statistically evaluated by GE21 based on QA/QC samples (analysis of certified reference materials, field duplicates and sample split duplicates, fine and coarse blanks) and via the execution of twin holes.

GE21 is a Brazilian based engineering consultancy with considerable experience in resource modelling and estimation. They consider the assay results to be of sufficient precision and accuracy to support the estimation of the mineral resources. Estimation Methodology & Reporting of Mineral Resources: High-grade capping supported by statistical analysis was completed on 2 metre composites and applied to the Project resource estimate.

The MRE was completed using the LEAPFROG EGDE software to generate a block model consisting of parent blocks measuring 50 metres x 50 metres x 4 metres with sub-blocks of 12.5 metre x 12.5 metre x 2 metre dimensions. Variography was performed for each of the five geological domains in the Project zone, for three groups of elements: Heavy Rare Earth elements plus yttrium (Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Y), Light Rare Earth elements minus cerium (La, Pr, Nd, Sm, Eu), and cerium (Ce), which showed a poor correlation with the other two groups. Grade interpolation for each of the 15 rare earth elements was performed via Ordinary Kriging into the parent blocks using hard boundaries.

Estimation was conducted using a strategy to control geometry and number of samples in the interpolation. Block estimation was validated visually, by global bias analysis and by trend analysis. In-situ bulk density was assumed to have a value of 1.8 t/m3 for the pedolith profile, based on similar projects in the region.

The MRE is classified as inferred mineral resources. The classification was based on level of confidence in the data, geological continuity, and geostatistical parameters appropriate to deposit type.
