The Masato deposit outcrops on the neighbouring Oromin Joint Venture Group ("OJVG") property to the east of the ML approximately 2 km from the Sabodala mill. The OJVG has defined an open pit mineable reserve at Masato. The deposit has a strike length of over 2 km. Gold is hosted in a shear zone that strikes north and sits immediately east of the Teranga/OJVG property boundary in the main deposit area.
The Dinkokhono deposit is part of the Niakafiri Shear system located about 1 km north of the Niakafiri deposit. Some of the mineralization defined by earlier drilling is included in the Inferred Resource reported from Niakafiri. Drilling in 2012 was intended to infill previous drilling and test for crossing structures, however, this was deferred to 2013.
Drilling in 2012 established the continuation of the Mamasato deposit located directly across the boundary on the OJVG property onto the Sabodala ML. Gold mineralization is contained in veins with variable strike orientations. Additional drilling is planned to delineate this potential resource in 2013.
In total, we drilled 104,400 metres at a cost of $26 million on the ML in 2012. The original ML budget was $20 million for 2012 but was expanded during the year to follow up on positive drill results at Sabodala.
We continue to methodically explore our large Regional Land Package (RLP) and are in the process of systematically building a pipeline of prospects. Unlike other West African nations, Senegal is a relative newcomer to gold mining and exploration and we look forward to discovering world-class deposits and establishing Senegal as a regional mining leader.
We currently have 10 exploration permits encompassing approximately 1,200 km2 of land surrounding the Sabodala ML (33 km2 exploitation permit). Over the past 24 months, with the initiation of a regional exploration program on this significant land package, a tremendous amount of exploration data has been systematically collected and interpreted to prudently implement follow-up programs. Targets are therefore in various stages of advancement and are then prioritized for follow-up work and drilling. Early geophysical and geochemical analysis of these areas has led to the demarcation of at least 40 anomalies, targets and prospects and we expect that several of these areas will ultimately be developed into mineable deposits. Through 2012 we were able to identify some key targets that though early stage, display significant potential. However, due to the sheer size of the land position, the process of advancing an anomaly through to a deposit takes time as it is imperative that work is done systematically.
During 2012 we completed 62,500 metres of RAB drilling, 42,300 metres of RC and 2,400 metres of diamond drilling on 25 of our anomalies and targets, at a cost of $19.1 million. Highlights from the 2012 drilling program are:
-- The discovery of a new prospect at Tourokhoto-Marougou with a minimum strike length of 1,200 metres.-- Identification of significant mineralization from RAB drilling at Saiensoutou extending for at least 1,400 metres in strike length.
A 4,500 metre program of infill RC drilling commenced at Marougou in the fourth quarter of which 2,900 metres were completed at the end of the year. The program was designed to infill drill on 200 metres spaced lines to establish the continuity of the mineralization discovered earlier in the year. The remainder of the program will be completed in the first quarter of 2013.
