Dongwe
IOCG New Copper and Rare Earths Drill Discovery
All Dongwe licences 100% owned by Zamare, totaling 386 km².
Licences 25521-HQ-LEL, 22562-HQ-LEL, 27909-HQ-LEL.
The Dongwe region is much less explored than the traditional Copperbelt and is ripe for discoveries.
Mineralisation in the region is believed to be of the IOCG (iron-oxide-copper-gold) deposit type which includes huge mines like Olympic Dam and Ernest Henry in Australia, amongst many others worldwide. The confirmed occurrence of granites in the vicinity is encouraging as such intrusive igneous bodies act as source rocks for IOCG mineralisation. BHP conducted a comprehensive airborne geophysical program cross a large area of North and Central Zambia using Falcon gravity and aeromagnetics to identify large scale IOCG targets for ground follow up and potential drilling. This program found the Kitumba underground mine (27.9mnt @ 2.3%) which Sinomine is building with capex of US$560mn and targeted capacity of 50,000tpa. Kitumba is an underground mine with copper mineralisation only starting at around 150m depth. Dongwe’s similarities toKitumba include host rock age, regional scale faulting and the same intrusive suite.
Zamare’s Dongwe project is also located 45 km south of the old Kalengwa Copper Mine. The mine, which closed in 1982 after 12 years of operation, is believed to have been one of the highest-grade copper mines in Zambia. Moxico the private UK-based miner is currently exploring around Kalenga.
Zamare’s work program on Dongwe has included the acquisition of the old BHP Falcon data, along with other historic data and then collection of soil geochemistry in a c. 9,000 point program on 200m centres across the whole licence. This work has identified four coincident gravity and magnetic anomalies which all have significant copper in soil anomalies. Field mapping by Zamare’s geologists has reported topographic highs, small mesas, composed of iron above each target, with alteration and brecciation in local country rocks. In 2024 Zamare commissioned its maiden drill program on one of the targets.

Zamare 2024 Drill Program
- Mutiple targets identified through regional soil sampling and historical airborne gravity and magnetics.
- Maiden drill hole on Msanza target hit massive brecciated and highly altered sulphide-rich system typical of IOCG mineralisation.
- Second hole drilled up to 0.3% Cu and 49m@1.06% TREO. Hole stopped prematurely in Cu & REE mineralization due to technical difficulties with drilling.
- The highest grade TREO was at the bottom of the hole, associated with intense skarn alteration zone, and it is open at depth and along strike.
- Kitumba, a Zambian IOCG copper mine, mineralization starts at 150m deep.
To follow up on these very exciting results, Zamare has outlined the following work program for 2026.
2026 Dongwe Work Program
- 2026 Plan is to assess Cu & REE discovery at depth and lateral continuity + additional prospects
- Trenching or pitting, plus mapping and sampling, along the full strike of the REE trend, to extend footprint
- Assess three other targets for potential copper and REEs.
- Airborne magnetics and radiometrics, geological integration, geophysical inversion for refine prospectivity and targeting.
- Forward modelling and inversion of the magnetics for subsurface IOCG target delineation.
- Q3 2026 drill testing for both copper mineralisation and TREO extension and the possibility of inferred resource definition.
