In Australia, at the Tropicana Mine there was a formal hand-over to the mine-based team of the accountability for all tenements within
60kms of the mine. Further to the south in the Tropicana joint-venture on the Oak Dam tenement, the Greenfields team continued
to work with the traditional owners to determine where access for exploration would be allowed. In the Laverton District, aircore
drilling was completed over priority targets with 91 holes drilled for a total of 5,742m. At the Strawbridge Project (100% AngloGold
Ashanti) the field work comprised geological mapping, surface soil geochemical sampling and first pass aircore drilling. A total of
778 soil samples and 197 aircore holes for 8,274m were completed over priority target areas.
In Colombia, drilling was completed at the Guintar project (100% AngloGold Ashanti) situated 40km west of Medellin. Three holes
for 1,219m were completed in the first half of the year. Final compilation and review recommended that no further work is required.
Work has now shifted to the Margaritas project area 2kms to the south where mapping, rock and soil geochemistry has been
completed. Reconnaissance work was conducted in other locations within Antioquia province in the mid-Cauca belt.
Generative exploration occurred in Brazil, Argentina, USA, Guinea and Tanzania. In a significant development, the Greenfields
exploration team signed a new farm-in and joint-venture agreement with Luna Gold to explore approximately 2,000km
2
tenement
package located in the Maranhão state of Brazil. In Tanzania the Meia license applications (850 km
2
) in the Lake Victoria
Greenstone Belt of Tanzania are pending and should be granted in the third quarter. The first phase of exploration was completed at
the Niandan license in Guinea (100km
2
, 90km from Siguiri) and 491 surface samples were collected. Early stage work is progressing
in Argentina and the USA.
BROWNFIELDS
During the first half of the year, Brownfields exploration activities were undertaken across the globe. Brownfields exploration,
including equity accounted joint-ventures, completed 285,877m of diamond drilling at a total expenditure for the six months ended
30 June 2016 of which $27m was capitalised and $33m was expensed.
South Africa: The mother hole of borehole UD59 successfully intersected a 1.82m thick VCR reef at 3,888m below surface on
11 April. Borehole UD60 reached 3,345m (284m drilled during the half) and continued to experience in-hole complications.
Borehole UD58A completed piloting to a depth of 3,027m. The final establishment of the ultra-deep derrick has been completed and
drilling commenced.
Tanzania: At Geita, drilling activities included infill drilling at Nyankanga Cut 9 (Block 5 UG), Nyankanga Cut 8, Star & Comet Cut
3, Geita Hill East Cut 2, and Mineral Resource delineation drilling at Star & Comet UG and Geita Hill East UG. A total of 10,372m
was drilled, comprising 4,392m reverse circulation (RC) and 5,980m diamond drilling (DD).
Guinea: At Siguri, a total of 29,415m was drilled. Exploration drilling included infill and reconnaissance drilling at Bidini North,
Bidini South, Soloni, Kalamagna PB2, Seguelen PB2, Seguelen satellite pit, Silakoro, Kami ‘starter pit’, Balato NE and sterilisation
drilling at Boukaria. Additionally, exploration supported the drilling of 12,893m allocated to Advance Grade Control within the Kami
starter pit.
Ghana: At Iduapriem, on the Bankyem/Block 1E target, the remaining trenches from 2015 exploration were sampled early in the first
quarter. A total of 1,597m drilling was completed over the target, comprising 421m RC and 1,176m DD. At Block 4S, 2,456m drilling
was completed, including 501m RC and 1,955m DD, with some encouraging assay results returned. Within the southern area at Block
7&8, a total of 796m were drilled during the quarter with some encouraging results. The programme is ongoing.
Democratic Republic of the Congo: At Kibali, exploration focused on Kombokolo, the Agbarabo-Rhino-Pakaka corridor, Tete
Bakangwe, Sessenge SW and the KCD super pit. The forecast production shortfall has resulted in an emphasis on projects
with potential to deliver oxide ounces to the plant in the relatively short term. Regional targets explored include Aindi Watsa,
Memekazi Ridge and Zambula. A total of 7,953m was drilled near mine and 3,519m was drilled on regional targets.
Republic of Mali – At Sadiola and Yatela, RC drilling totaling 11,716m was completed during the first half of the year. Drilling
focused on Sadiola North/FN (4,624m), FE2S (5,454m) and FE1W (1,638m).
In Argentina, drilling commenced at Cerro Vanguardia during Q2 after a delayed start with most of the drilling meters completed at the
nearby Claudia joint-venture. During the second quarter 4,174m were drilled in total, including 3,618m at the Claudia joint-venture.
In Brazil, exploration continued at the Cuiabá, Lamego and Córrego di Sítio production centers for AGABM with 61,221m drilled during
the quarter from the combined surface and underground drilling programmes.
At Serra Grande, 36,295m were drilled as part of the exploration and Mineral Resource conversion programmes. Surface exploration
continued as preparation to establish drilling targets.
In Colombia, the Gramalote joint-venture completed 1,279m of drilling to support site and infrastructure investigations as well as infill
drilling to better define the saprolite horizon. At La Colosa, 1,453m were drilled as the site investigation geotechnical drilling continued.
The Quebradona JV programme did not complete drilling during the half year and was focused on study work.
In Australia, at Sunrise Dam drilling targeted Vogue South, Vogue Deeps, north extensions to Cosmo and Cosmo East, Carey Shear,
Below Carey high grade zone and Ulu Steeps for a total of 28,758m.
At Tropicana, a 100m x 100m exploration drilling programme continues to test the along-strike and down dip extensions of the
Tropicana gold system to provide data for the Long Island Mining Study. Infill drilling was also carried out on the Havana South high
grade zone identified during the June quarter. A total of 16,670m of RC and 34,695m of DD drilling was completed in the first half of
2016. A Mineral Resource model update is in progress.
A new regional exploration group was set-up based at Tropicana to manage the TJV exploration tenements (excluding the mine
lease). In the first half of the year, regional exploration consisted of drilling and a ground-based geophysical survey. Aircore, RC and
DD totalled 13,360m.
The regional dataset review and a large amount of regional structural re-interpretation work to aid targeting has been completed with a
number of areas identified as being potentially prospective. A large number of these will be systematically targeted.
