Yamana Gold Inc. (USA) (NYSE:AUY) provided an exploration update for its Chapada and Jacobina mines. Results from the recent exploration programs at these mines continue to support a positive operational outlook and strong long-term potential for these operations.
Significant results to date from the Company’s Brazilian exploration program include:
- Chapada – exploration drilling at the recently discovered Sucupira target continues to support the extension of the high grade gold and copper core, and surrounding moderate to low grade gold and copper halo to the southwest.
- Jacobina – the infill drill program is returning assay results at or significantly above reserve grade along mineable widths at Canavieiras Sul, Norte and within the Morro do Vento mine complexes.
Sucupira is a recent discovery that has been quickly advanced at Chapada.
During the first half of 2015, over 4,230 metres of exploration drilling was completed in 12 holes at the Sucupira target in support of the objective of further testing the target that was discovered in 2014. The Sucupira target is located 200 to 300 metres beneath the surface, aligned northeast to southwest and immediately parallels the main Chapada pit, potentially accessible from the pit bottom.
The Sucupira mineral body is comprised of a high grade gold and copper cigar-shaped core surrounded by a broad, low grade halo. The high grade core is associated with quartz veins and contains chalcopyrite, pyrite and bornite. The bulk mineralization surrounding the high grade core has grade and thickness similar to those at Chapada and Corpo Sul.
Drilling at Sucupira has intersected mineral intervals along a 1.1 kilometer northeast-southwest trend and supports the extension of the Cava Norte mineral body for a minimum of 1.5 kilometers to the southwest. This mineral trend remains open to the southwest and to depth. The 2015 exploration drill program has confirmed continuity of the mineralization zone with numerous high grade intercepts.
Select assay results include:
- 79.7 metres at 0.44 grams per tonne (“g/t”) Au and 0.51% Cu from 212.2 metres; including
- 31.3 metres of 0.83 g/t Au and 0.67% Cu from 252.0 metres;
- 93.0 metres at 0.21 g/t Au and 0.31% Cu from 204.0 metres; including
- 8.1 metres at 0.65 g/t Au and 0.68% Cu from 266.9 metres; and
- 107.5 metres at 0.30 g/t Au and 0.42% Cu from 226.4 metres; including
- 30.6 metres 0.81 g/t Au and 0.91 Cu from 302.4 metres.
More detailed results from the exploration program at Sucupira are provided in the attached Appendix 1.
Exploration at Chapada’s Sucupira target will continue to test both the southwest strike and down dip extensions of the mineral body with the objectives to expand the size and geometry of the mineral body. Sucupira is expected to increase overall mineral resources at Chapada at higher grades.
Exploration at Jacobina in 2015 is focused on infill drilling of certain high grade zones in support of advancing development into the high grade areas of the mine and to test down dip extensions of these higher grade areas. Advancing exploration and development of the high grade areas identified as Canavieiras Norte and Sul and Morro do Vento has been a priority at Jacobina.
During the first half of 2015, over 7,200 metres of infill drilling was completed in 66 holes at the Jacobina mine. The objective of the infill drilling program is to improve geologic knowledge and mineral continuity in support of mineral resource conversion and mineral reserve delineation. The specific goal of the infill drill program at Canavieiras Norte and Sul and Morro do Vento is to better define the mineralized reefs found within the Upper Conglomerate units of the Serra Di Corrego Formation. The infill program will outline the ore bodies at a nominal 30 metre by 30 metre grid with locally tighter spacing. Results received to date are encouraging, with many holes reporting composite grades at or above reserve grade with some local intercepts reporting significantly higher than reserve composite grades. The recent infill drilling campaigns at Jacobina are particularly encouraging given that the targeted zones are areas close to existing infrastructure and/or areas already having development plans in place.
In addition to the infill program, an exploratory drill program began late in the second quarter to test for the deep, down dip extensions of the prolific Main Reef ore bodies mined at João Belo and Morro do Vento. The four hole program will test the Morro do Cuzcuz and Canavieiras Norte and Sul mines for the Main Reef to depths approaching 1,000 metres below the surface.
Figure 1 shows a plan view map of the geology on the left with infill targets highlighted in black rectangles and deep exploration targets located by blue dots. The right portion of the figure shows the stratigraphic column of the geologic units found at Jacobina. The infill program will test various mineral reefs in the Upper Conglomerate package and the Deep Main Reef exploration program will test for the down dip extensions of the high grade Main and Footwall Reefs previously exploited at João Belo.

Composite assay results from the 2015 Infill drill programs at Canavieiras Norte and Sul support the higher average reserve grade at the Canavieiras mine complex, with local results significantly exceeding the reserve grades along significant intercept widths.
Select composite assay results from Canavieiras Norte include:
- 1.5 metres of 14.32 g/t Au from 85.5 metres; including
- 0.5 metres of 40.63 g/t Au from 86.5 metres;
- 7.1 metres of 12.35 g/t Au from 160.4 metres; and
- 15.5 metres of 6.49 g/t Au from 137.0 metres; including
- 1.8 metres of 18.07 g/t Au from 146.7 metres.
Select composite assay results from Canavieiras Sul include:
- 9.4 metres of 8.72 g/t Au from 156.1 metres;
- including 1.9 metres of 17.7 g/t Au from 156.1 metres;
- 6.3 metres of 15.93 g/t Au from 135.0 metres;
- including 1.85 metres of 27.86 g/t Au from 137.7 metres; and
- 2.63 metres of 12.17 g/t Au from 144.9 metres.
More detailed results from the infill program at Canavieiras Norte and Canavieiras Sul are provided in the attached Appendices 2 and 3.
The new geologic and assay data from the infill programs at Canavieiras Norte and Sul is updated daily to the mine database in an effort to continuously improve the geologic, structural and grade shell models. The updated models will result in better defined ore zones and will support planned development into these higher grade ore zones starting in the third quarter of 2015.
MORRO DO VENTO
The infill drilling program at Morro do Vento aims to intersect the Main Reef Zone, Footwall and Basal Reef. Results to date have returned visually interesting results at the Main Reef Zone with visible gold in almost all holes, and have confirmed high grade zones associated with the Main Reef Zone and to the Hangingwall Zone. The Main Reef Zone is characterized by an interfingering of narrow layers of quartzite and small to medium pebble conglomerates.
Select assay results include:
- 2.0 metres of 5.51 g/t Au from 94.0 metres; including
- 0.5 metres at 14.10 g/t Au from 96.0 metres
- 3.0 metres at 1.57 g/t Au from 100.0 metres; including
- 0.7 metres at 4.10 g/t Au from 100.0 metres; and
- 2.0 metres at 9.31 g/t Au from 77.5 metres; including
- 0.5 metres at 34.63 g/t Au from 78.5 metres.
