Rockridge Capital Corp.: Significant Gold Discovery Identified North of Fatou Main Zone
September 05, 2013 (Source: Marketwire) — Rockridge Capital Corp. (TSX VENTURE:RRC) (“Rockridge”; the “Company”) is pleased to announce results from the 2013 drilling campaign.
- Twelve diamond drill holes (DD), totalling 3,228m, and fourteen reverse circulation (RC) drill holes, totalling 1,942m, were drilled, logged and sampled;
- Significant gold mineralisation was intersected in 3 target areas, namely G1, G2 and G12;
- The best result from this program is the new gold discovery in target G12 (12m grading 5.85g/t Au), which is located approximately 1km on strike to the NNW from the Fatou Main Zone (target G3);
- Geophysical response suggests the structure associated with the new discovery has a potential strike length greater than 1.8km;
- Mineralisation encountered in drilling to date shows that the Fatou project bears similarities to a number of large gold deposits in the West African craton;
- e.g. Essakane and Taparko in Burkina Faso, in being located on secondary splays off a major NE-trending shear (the Banifing Shear Zone), and;
- e.g. Sadiola, Tabakoto and Morila gold mines in Mali, in being spatially associated with a granitoid.
- Table 1 below summarises the best drill intercepts from this campaign.

Rockridge president Karl Kottmeier commented, “We are excited to have made this new discovery as it is on strike and more than a kilometre from the Fatou Main Zone. The impressive gold grade in hole RCF 253 is greatly encouraging and reminiscent of some of the results encountered in previous drill campaigns at the Fatou Main Zone. I am also pleased to report to shareholders that, based on a recent visit, the political and security situation in Mali is vastly improved. Yesterday in Bamako, I.B. Keita was sworn in as president and his new government will take office shortly.
Rockridge technical staff are currently completing plans for our next exploration program at Fatou and we expect to be back to work at the project this fall.”
The Fatou Gold Project
The Fatou gold project is located 270km southeast of Bamako, the capital of Mali, approximately 20km north of the border between Mali and Cote d’Ivoire.

The geological knowledge base for the 250km² Fatou project has increased substantially since the successful completion of a systematic exploration programme that included location of and mapping of current and historical artisanal miners sites, geological mapping, airborne geophysics, ground based IP survey in selected areas, geochemistry soil grid sampling and selected traverse sampling (i.e. Metal Mobile Ion – MMI sampling and auger drilling to 15m with the sampling of the upper portion of the saprolite zone).
Twelve (12) prospective targets have been identified, and named G1 to G12. Based on geology and the nature of mineralisation, the area has been divided into a Western Zone (targets G3 to G7 and G12), and an Eastern Zone comprising a continuous mineralised corridor covering an 11km strike length (targets G1, G2 and G11) and non contiguous targets G8, G9 and G10 (Figure 1).
WESTERN ZONE NEW DISCOVERY – TARGET G12
Following the discovery of gold mineralisation in the Fatou Main zone (Target G3), drilling was extended northwards into target G12 and has identified a number of NNW-SSE trending mineralised linear structures. The best mineralised intercepts were recorded in RC borehole RCF253 and diamond drill borehole DDF116. The true thickness of the mineralised zone assumes near vertical dip as determined from core orientation analysis of DDF116.
- RCF253 intersected 5.85 g/t Au over 12m (7.7m true thickness) between 78m to 90m, including 11.16 g/t Au over 6m (3.8m true thickness) between 80m to 86m.
- DDF116 intersected of 1.45 g/t Au over 18.5m (9.6m true thickness) between 173.5m to 192m, including 2.56 g/t Au over 7m (3.8m true thickness) between 183m to 190m.
Pervasive mineralisation is evident up to 7m from the high grade section. The linear structures are similar in sulphide composition and alteration type to that of the Fatou Main Zone (G3). Quartz veins associated with the mineralisation in DDF116 dipped westwards. Future drilling of these structures will be at an azimuth towards the east.
The geophysical response associated with the linear structures indicates a potential NNW-SSE strike length of more than 1.8km.
Assays from 366 samples are outstanding (drill holes RCF246 to RCF253 (Figure 1)), which targeted linear structures in G12.

The previously described technical work has indicated the Eastern Zone to be highly prospective. Several drilling campaigns between May 2010 and April 2012 were successfully completed and have identified a distinctive style of mineralisation that shows great similarities to the Mana super pit, Wona-Kona Mine, in Burkina Faso. Such similarities include silicification and deformation in very pyritic graphitic schists, and alteration including chlorite and carbonate.
Boreholes DDF107, DDF110 and DDF111 showed pervasive mineralisation over significant lengths in the core, and arsenopyrite was noted in DDF111. Whilst assay results were disappointing in these holes, the nearby RCF255 intersected 1.19 g/t Au between 13 and 15m core depth (i.e. less than 10m below surface). Gradient IP shows the trend of this auriferous zone over a 1.3km strike length, and this requires further follow up.
In the northern section of G2, continuation of gold mineralisation from the Fininko area is evident with an intersection in hole RCF 245 of 1.18 g/t over 3 metres between 166 and 169m core depth.
In borehole DDF109 (the borehole that most typifies a Wona pit analogy) several quartered 1m borehole core samples were sent to an independent laboratory in South Africa and the best assay grades over 1m recoded were 1.95 g/t, 0.92 g/t, 0.56 g/t, 0.55 g/t and 0.40 g/t. The mineralising system is obviously auriferous.
There are some 253 outstanding assays in the eastern section, the vast majority in G1. Further drilling is planned to follow up this highly prospective zone.
