Copper Intelligence Announces Significant Upgrade To Reported Copper Grades at Butembo
OTC: CUAI
Overview
Copper Intelligence Inc. announced that it has received accredited independent laboratory assay results for the first 67 samples collected from its Butembo Copper Project in the Democratic Republic of Congo (DRC), according to the company. The samples were initially analyzed onsite using handheld X-ray fluorescence (XRF) equipment as a rapid exploration screening tool to identify and prioritize mineralized zones, with these preliminary results considered indicative and accredited independent laboratory assays intended to provide definitive analysis, the company stated.
According to the company, the verification program confirmed significant copper mineralization across the sampled areas. The company reported that 21 samples representing the higher-grade population (greater than 1% Cu) averaged 8.2% Cu in independent laboratory assays, compared with 3.7% Cu from preliminary field XRF analyses. This sample was from 6 holes, with a further 10 under analysis, according to the company.
Key Highlights
- Accredited independent laboratory assays confirm significant copper mineralization at the Butembo Copper Project in the DRC, according to the company.
- The initial verification program covers 67 samples.
- 21 higher-grade samples (greater than 1% Cu) averaged 8.2% Cu, compared with 3.7% Cu from preliminary on-site handheld XRF analyses.
- The company states that results indicate preliminary field analyses may have understated grades in higher-grade mineralized zones.
- Improved sample preparation procedures are being implemented, and accredited laboratory results will progressively replace preliminary field data, according to the company.
- The company states that results strengthen confidence in the copper mineralization identified at Butembo.
Strategic/Operational Context
Management considers the variance largely reflects sample preparation and homogeneity factors affecting early-stage field analyses, according to the company. While handheld XRF remains useful for rapidly identifying mineralized zones, the company states that analytical reliability depends on representative sample preparation, including effective crushing and pulverization. For context, the company notes that average copper ore grades are reported at 2.56% in the DRC and 0.55% in Chile, the world's largest copper producer, according to the CRU Group.
Following its review of the results, Copper Intelligence is implementing improved sample preparation protocols to enhance the accuracy, consistency and repeatability of future field analyses, according to the company. Accredited laboratory assays will progressively supersede preliminary handheld XRF results for the corresponding samples as verified results become available and are incorporated into the project database, the company stated. The company regards this conservative reporting approach as prudent and consistent with industry best practice, particularly during early-stage exploration. Management believes the results strengthen confidence in the grade and significance of the copper mineralization identified at Butembo and support continued exploration across the project, according to the company.
Quality Assurance and Quality Control
According to the company, the verification program included Copper Intelligence's internal quality assurance and quality control ("QA/QC") procedures, including control samples inserted into the analytical stream. The accredited independent laboratory also applied its established QA/QC protocols, including standards, blanks, duplicates and other controls to monitor analytical accuracy and precision, the company stated. Management views these combined procedures as supporting confidence in the reliability of the reported assay dataset.
Copper Intelligence's President, Alan Kessler, commented: "From the outset, our handheld XRF program was designed as a rapid exploration tool to identify and prioritize mineralized zones rather than as a substitute for accredited laboratory assays. We have consistently maintained a conservative reporting philosophy and have always intended to rely on independent laboratory results for definitive reporting. The fact that our first batch of accredited laboratory assays has returned substantially higher copper grades within a number of our strongest mineralized samples is highly encouraging. At the same time, the program has provided important technical information that allows us to further improve our field sample preparation procedures. We believe these results strengthen confidence in the quality and significance of the mineralization identified to date at Butembo and support our continued exploration efforts across the project."
What to Watch Next
- Accredited laboratory assays for the remaining samples from the 10 holes currently under analysis, which are expected to progressively supersede preliminary field XRF results as they become available, according to the company.
- Implementation of improved sample preparation protocols intended to enhance the accuracy, consistency and repeatability of future field analyses, according to the company.
