Copper Intelligence Reports Drilling Results Validating Copper System at Butembo, Eastern DRC
OTC: CUAI
Overview
Copper Intelligence ("the Company") announced a comprehensive update on exploration results from its flagship Butembo Copper Project, located in the eastern Democratic Republic of Congo (DRC), according to the company. The Company stated that it considers the results obtained from this maiden drilling campaign to represent a major step forward in unlocking the value of the Butembo Copper Project and further establishing the project as a highly prospective copper discovery within one of the world's premier copper-producing jurisdictions, according to the company.
According to the company, results from the maiden diamond drilling campaign continue to demonstrate the presence of a substantial copper mineralising system hosted predominantly within a package of prospective schist sequences, which the company describes as similar to the package mined at the Kilembe Copper Mine in neighbouring and adjacent Uganda, a mine that the company states extracted 420,000 tons of copper metal over its life to date. The company stated that drilling has consistently intersected broad zones of copper mineralisation across multiple sections of the project area.
To date, the company reports that thirteen diamond drill holes and one deep extension hole have been completed, with numerous intersections returning what the company describes as economically significant copper grades over mineable widths. The company noted the repeated occurrence of mineralisation within laterally continuous schist-hosted horizons and the recognition of native cuprite within several drill holes, including BCDD001, BCDD006 and BCDD007.
Key Highlights
- Copper mineralisation intersected in all 13 principal drill holes completed, according to the company.
- Mineralisation remains open along strike and at depth, according to the company.
- Schists have been confirmed as the principal host lithology for copper mineralisation, according to the company.
- Highest-grade intersection returned 7.55 metres at 5.39% Cu from surface in hole BCDD001, according to the company.
- Broad intervals include 29.1m at 1.28% Cu from 1.0m in BCDD006; 16.0m at 1.65% Cu from 23.0m in BCDD007; 12.5m at 1.78% Cu from 35.5m in BCDD011; and 11.1m at 2.75% Cu from 17.9m in BCDD013, according to the company.
- Native cuprite identified in mineralised zones within BCDD001, BCDD006 and BCDD007, according to the company.
- Mineralisation occurs over a strike length exceeding the current drilling area and remains open, according to the company.
Strategic/Operational Context
According to the company, the Democratic Republic of Congo hosts some of the world's largest and highest-grade copper resources, largely concentrated within the Central African Copperbelt, which are commonly hosted within sedimentary units of the Roan and Kundelungu Groups. The company stated that the Butembo Copper Project presents a somewhat different geological setting, with the drilling programme establishing that copper mineralisation at Butembo is primarily hosted within a sequence of highly prospective metamorphosed sedimentary schists that display strong structural alterations and evidence of hydrothermal fluid activity.
The company stated that the continuity of mineralisation across numerous drill sections strongly supports a district-scale mineralising event, and that copper occurs consistently within the same schist package, suggesting the presence of a predictable stratigraphic control that may facilitate future resource delineation. The company noted that the recognition of native cuprite, a copper oxide mineral it describes as indicative of strong copper enrichment processes, within holes BCDD001, BCDD006 and BCDD007 demonstrates the intensity of mineralising fluids and provides additional confidence regarding the fertility of the Butembo copper system. The company said it is also considering whether the cuprite might signal areas of significant supergene enrichment.
Richard Rice, the company's head of Technical Services and Chief Geologist, commented: "The drilling results achieved to date at Butembo have materially exceeded our initial expectations. The consistency of copper mineralisation, the exceptional grades encountered in several holes, and the presence of native cuprite within the mineralised schist package provide compelling evidence that we are dealing with a significant copper system. Particularly impressive are the broad intersections returned in holes BCDD006, BCDD007, BCDD011 and BCDD013, together with the outstanding near-surface grades encountered in BCDD001. We believe Butembo has the potential to emerge as an important new copper project globally, and we look forward to aggressively advancing exploration in the months ahead. Internally we are discussing the possibility that we have discovered a new copper district which links up towards what was mined at Kilembe, some 65km away along the same strike direction. We have an exceptional geological team on the ground and will continue to expand and define what we believe to be a discovery of global significance."

The company stated that the drilling completed to date has identified several characteristics it associates with significant copper deposits, including a consistent stratigraphic host horizon, strong structural controls, broad intervals of continuous mineralisation, multiple higher-grade shoots, near-surface mineralisation, evidence of copper enrichment through native cuprite development, and persistence of mineralisation from surface to depth.
What to Watch Next
- Extending mineralisation along strike, according to the company.
- Testing down-dip continuity, according to the company.
- Defining higher-grade copper shoots, according to the company.
- Evaluating regional targets generated through geological mapping and geophysics, according to the company.
- Advancing the project toward an initial S-K 1300 compliant mineral resource estimate under United States Securities and Exchange Commission (SEC) modernized mining disclosure standards, according to the company.
