Exploration drilling at the Ntaka Hill ultramafic intrusion outside the Sleeping Giant Zone has focused on:
-- Testing previously untested electromagnetic anomalies;-- Testing coincident nickel and copper soil anomalies; and-- Following up on nickel mineralisation intersected south and east of H zone in 2011.
To date, eleven drill holes totalling 1,802 metres have been completed to test seven exploration targets, all of which have intersected various concentrations of sulphides hosted within the Ntaka Hill ultramafic intrusion.
During the quarter, a 2,409 line kilometre airborne magnetic and versatile time-domain electromagnetic ("VTEM") survey was completed over selected regional areas. The survey identified 25 new high priority conductor anomalies within the northern portion of the Nachingwea Project. The delineation of multiple late time electromagnetic anomalies enhances the regional prospectivity of the Nachingwea property.
Lionja Intrusion
Exploration drilling at the Lionja ultramafic intrusion located 8 kilometres to the south of Ntaka Hill intersected new high-grade and disseminated nickel sulphide mineralisation. Four diamond drill holes totalling 1,049 metres were drilled to target extensions to the Lionja intrusion where previous drilling had reported up to 2.25 metres at 2.03% Ni and 0.41% Cu. All holes intersected wide intervals of disseminated nickel sulphide mineralisation which exhibit high nickel tenors similar to the Ntaka Hill sulphide zones, the highlights of which included:
-- 1.07% Ni & 0.10% Cu over 5.0 metres (including 0.60 metres at 7.1% Ni & 0.44% Cu)-- 0.67% Ni & 0.12% Cu over 8.4 metres (including 0.45 metres at 3.52% Ni & 0.60% Cu)-- 0.51% Ni & 0.12% Cu over 8.8 metres
As with the Ntaka Hill intrusion, the Lionja high-grade lens occurs within a wider disseminated nickel sulphide halo. An initial review of the gravity results over the Ntaka trend stratigraphy has highlighted the potential for a link between the Ntaka and Lionja intrusions, which are located approximately 10 kilometres from each other.
Zeppelin
During the quarter, the Company confirmed the discovery of a new nickel sulphide zone 750 metres east of the Sleeping Giant Zone. This followed the completion of five diamond drill holes totalling 838 metres to follow up initial nickel sulphide mineralisation intersected east of H Zone in 2011 drilling.
Also, surface and borehole electromagnetic surveying that was completed in November 2012 identified a highly conductive area at the southern end of Zeppelin that was subsequently drilled and intersected various intervals of net-textured (and disseminated) sulphides.
Lightning
A single diamond drill hole totalling 392 metres was drilled at Lightning, 100 metres south of H Zone, to follow up high-grade nickel sulphide mineralisation and a new off-hole electromagnetic anomaly identified from previous drilling in 2011. The new hole intersected a zone of strongly disseminated to net-textured sulphides grading 1.92% Ni and 0.26% Cu over 4.5 metres from 263 metres.

HOG Prospect
As part of a 1,500-2,000 metre reverse circulation ("RC") drilling program to test selected high priority regional VTEM and geochemical anomalies, five RC holes totalling 424 metres were completed at the HOG target. Of potential significance is the identification of a high amplitude late time electromagnetic anomaly, coincident with the HOG gold prospect, where surface gossan sampling returned values of up to 4.96 g/t Au and 0.64% Cu.
