ASX-listed Tawana Resources’ Mofe Creek Zaway iron ore prospect in Liberia is delivering extremely positive results – highlighting its potential to be a high grade iron ore producer.This latest discovery (additional high-grade outcropping coarse grained itabirite mineralisation at the Zaway prospect) follows the company’s recent preliminary assessment and metallurgical announcements which indicated the itabirite mineralisation has excellent weight recoveries of between 44% and 57% and concentrates into a high quality, 60%+ iron product from a simple coarse crush and gravity processing circuit.“The occurrence of direct shipping ore (DSO) magnetite boulder float and exceptionally coarse grained; up to 2 cm particle size itabirite at Zaway adds further encouragement to the potential discovery of blind DSO similar to that mined at the historic Bomi Hills mine 20km along strike,” says Tawana Resources MD, Len Kolff. He adds, “This latest new discovery of high grade iron ore demonstrates why we consider the Mofe Creek iron ore project, at only 20 km from the coast, is an exciting new iron ore discovery in Liberia, West Africa.” Itabirite outcrops over a combined 1 km strike have been mapped and sampled at the main Zaway prospect with grades ranging between 44% to 62% iron and low contaminants. On the main target, outcrops dip steeply to the south and occur along both flanks of a 1.35 km x 280 m hill. Additional itabirite outcrops have been mapped along low ridges to the west and north of the main Zaway prospect hill over a combined strike length of >4.5 km. Due to the lack of outcrop on top of the hill, pitting has commenced to determine the geology in-between the iron outcrops and the potential width extent of the mineralisation discovered.
The extremely coarse grained nature of the itabirite and presence of metre scale magnetite boulder float down slope of the outcrops is extremely encouraging and confirms the prospectivity of the Mofe Creek discovery.The structures mapped to date could be interpreted to represent a south dipping synformal fold structure with coarser and higher grade iron formation occurring along the footwall contact. This is the same structural and lithological setting hosting the historic Bomi Hills mine 35 km along strike to the east, which produced 50 Mt of DSO through the early 60s to late 70s. Although smaller scale then the Bomi Hills pit (roughly 750 x 500 m), Zaway represents a high priority target with outcropping high-grade itabirite with DSO boulder float and the potential for blind magnetite DSO along the footwall contact.
Zaway occurs in-between the Gofolo and Koehnko drilled prospects with a combined high-grade itabirite exploration target of 95 Mt and is
within 20 km of the coast. A global exploration target size potential of between 360 Mt and 670 Mt of friable mineralisation has been estimated for the Mofe Creek project area. This estimate includes both friable itabirite and friable intermixed itabirite/amphibolite mineralisation. The estimate does not include hard itabirite below base of oxidation, potential blind DSO or additional mineralisation associated with targets which have not had sufficient field work to date to justify inclusion.
About Mofe Creek
Mofe Creek is located within one of Liberia’s historic premier iron ore mining districts. The project is 10 km along strike from the abandoned Bomi Hills mine, 80 km along strike from the historic Bong mine, 45 km from Mano River mine and 20 km from Bea Mountain resource.
