The Dongwe region is much less explored than the traditional Copperbelt and is ripe for discoveries. Zamare’s project is 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. Kalengwa was reported to have mined a high-grade supergene core that yielded an average grade of 27% Cu. This core comprised around 20% of the ore body. The ore was so high grade that it was trucked unprocessed to Kitwe for direct smelting. Total production of 1.9 Mt of 9.44% Cu and 50 g/t Ag was reported from the open pit resulting in circa 15,000 tonnes of copper production per annum for the 12 years of production.

Kalengwa, along with the other mineralisation being investigated in this region, is of a different style to the traditional Copperbelt. 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.

The Kitumba project 230 km south-east of Dongwe is another example of IOCG copper mineralisation style. Similarities to Kalengwa include host rock age, regional scale faulting and the same granites.
Zamare's regional targeting that led to the identification of Dongwe as a target was corroborated by field work in October 2020 when 15.9% Cu and 0.57 g/t Au were sampled from artisanal pits active on the licence area. Since then, Zamare has acquired another licence that has grown the total project area to an impressive 781km². The acquisition was fueled by newly obtained historic BHP maps that highlight drill targets across Dongwe.
Realising the value and amount of historic data, Zamare has been actively seeking additional sources of information and building a comprehensive database. New data acquired in 2021 includes BHP magnetic and gravity results, mapping and interpretations as well as geochemical results from Western Mining Corp. (a precursor company to First Quantum Minerals Limited) and Roan Selection Trust.

The Zamare team noted inconsistencies between geochemical results in historic data and decided to test previous work with an orientation sampling programme. The orientation sampling was completed in June 2021 with analysis and interpretation on-going, the results will be used to optimise a larger sampling programme across the licence.
In addition to the orientation work, the Zamare team also sampled historic mineral occurrences and visited BHP targets in June 2021, results of the work are pending.
