Freetown — London Mining’s extended drilling programme at its flagship Marampa project in northern Sierra Leone has uncovered two structures with an estimated inferred resource of 111 million tonnes grading 33% iron.

Consequently, the company is now targeting a steady-state 9 million tonnes per annum mining operation, with more than a 20 year mine life. The newly discovered Campbell Town ridge and Hospital ridge structures are connected to Marampa’s Masaboin Hill and Ghafal Hill zones. London Mining chief executive, Graeme Hossie, said he was excited by the new discovery, noting that a “higher grade fraction … has the potential to significantly enhance the economics of the project”.

This ‘higher grade’ area consists of around 22 million tonnes of weathered ore – of which a fraction could be processed without milling – which could be blended with tailings to increase head grade to 26% Fe. London Mining believes this could extend Phase 1 from 5 years to over 7 years, with a 3 million metric tonnes per annum peak run rate.

At  Marampa, London Mining has almost completed its original drilling schedule – with nearly 27,000 of the planned 28,000 metres complete – however in light of this latest discovery the company says it has expanded the programme up to 40,000 metres.

With the additional drilling London Mining intends to expand and upgrade Marampa’s resource further.

London Mining revealed the Campbell Town and Hospital discoveries as part of its second quarter operational update. The company also highlighted that the construction of Marampa’s Phase 1 tailings operation was well underway, and the “majority of civil earthworks” were completed as scheduled, ahead of the rainy season.
