The 1,100m ASL project is located close to the southern limb of the Zambian copperbelt approximately 35 km from the regional centre of Kapiri Mposhi and 220 km north east of the State capital of Lusaka. The site is easily accessible via a 20 km gravel road leading from the sealed highway from Lusaka through Kapiri Mposhi towards Tanzania.

Based on drill results an interim resource of 10.7 Mt at 1.11% copper was estimated. The resource is non NI 43-101 compliant.

Discovered in 1922, the project deposits were first mined by underground workings, then developed as an open pit operation in the late 1960's. The operation closed due to the nationalization of the Zambian copper industry in the 1970's. A 2008 pre-feasibility study concludes that the project is economically viable at current prices.

The study contemplates the use of a mining contractor, for an open pit mining operation, operating 60t haul trucks and 100t excavators, on a two shift per day basis, six days a week. Local labour would be used extensively, with the mining contractors training local operators. The study has assumed an annual production rate of 1.6Mt per annum with an 18 month pre-production period. Mining would probably progress from the north to the south along the strike of the deposit.

The results of a metallurgical program indicate a potential 96% recovery of copper using conventional copper sulphide flotation technology, yielding a concentrate containing 28% copper.

The plant will comprise primary crushing followed by single stage autogenous milling and a standard flotation circuit followed by pressure filter drying, to recover a concentrate from the run-of-mine ore. The concentrate will be trucked about 200km to nearby smelters in Zambia for sale.

The proposed tailings dam is designed to allow surplus water to be recovered and returned for use in the process plant.

Process water can be abstracted either directly from the nearby Lumsemfwa River or from a dam to be constructed on the Lumsemfwa or one of its tributaries.

Electrical power can be sourced from either an existing National Grid power line, located 300m north of the planned open pit or from the nearby Lumsemfwa hydrostation.
