Argosy Minerals Limited has announced that it has been granted three exploration licences, through its wholly owned subsidiary Argosy Exploration Limited, over chromite prospects in Sierra Leone.
Argosy owns 100% of the exploration licenses.
Chromite in Sierra Leone
Chromite was first discovered in Sierra Leone by the Geological Survey of Sierra Leone at Jaluahun near the town of Senduma, Kenema District.
Regional Geochemical and Heavy Mineral Surveys established a north-east trending chrome province 40 kilometers wide by 120 kilometers long in the country.
All chromite bodies discovered to date lie within this chrome province and are associated with the Archean Greenstones of the Gori Hills, Northern and Southern Kambui Hills, or some other relict greenstone belts such as those found near Matakahun, Mapoima, Baraka, Gorauwahun, Tuba, Dodei, Lileima and Tomaju.
Gorahun Vaama Chromite Project
The Gorahun Vaama Chromite Project comprises a chromite exploration licence located in south-eastern Sierra Leone. The licence covers an area of 156 square kilometers.
Background
1. The Sierra Leone Geological Survey had in previous work indicated the presence of chromitite lenses in three localities:
(i) near the abandoned village of Jaluahun near the town of Sendumei,
(ii) near the deserted farm settlement of Tolobu, and;
(iii) 400 metres southwest of the Gorahun Vaama – Matakahun Road.
(ii) and (iii) are within short distances of the town of Gorahun Vaama.
2. Chromitite boulders were also observed strewn on interfluves, and;
3. Heavy mineral concentrate collected and examined in the course of geological mapping had indicated anomalous interfluves.
Bunumbu Chromite Project
The Bunumbu Chromite Project comprises a chromite exploration licence located in eastern Sierra Leone. The licence covers an area of 250 square kilometers.
Background
1. The Sierra Leone Geological Survey had in previous work indicated the presence of chromitite lenses in a number of localities – viz Dodei, Gbanahun, Kpetema, Masau, Tomaju, Lileima, Sembehun, Manjama and Bolu.
2. Chromitite boulders were also observed strewn on interfluves, and;
3. Heavy mineral concentrate collected and examined in the course of geological mapping had indicated anomalous interfluves.
Mayepema Chromite Project
The Mayepema Chromite Project comprises a chromite exploration licence located in south-eastern Sierra Leone. The licence covers an area of 138 square kilometers.
Background
1. The Sierra Leone Geological Survey had in previous work indicated the presence of a small hill near the villages of Gorauwahun and Tuba with chromite at CR2O3 ranging from 30.9 – 34.6%.
2. Heavy mineral concentrate collected and examined in the course of geological mapping had indicated anomalous interfluves.
