The road-accessible 48,043 hectare Água Branca Project (“Água Branca”) is located in the Tapajós Gold District. Talon holds option agreements to acquire a 100% interest in the Água Branca from several vendors, with net smelter return royalties of 1 to 2%.
Heaven West Zone
Recent work has led to the discovery of Heaven West, a zone of high-grade gold mineralization. High-grade grab samples from quartz veins include 132.2, 109.9, 107.0, 66.0 and 29.9 g/t Au. Highlights from channel sampling of quartz veins and hydrothermally altered monzogranite include:
- 48.5 g/t Au over 1.50 metres in PGM-11
- 14.5 g/t Au over 1.40 metres in CGM-02*; including 37.6 g/t Au over 0.40 metres
- 3.23 g/t Au over 5.70 metres in PGM-01**; including 22.6 g/t Au over 0.20 metre
- 44.3 g/t Au over 0.30 metres in PGM-15

Geological and structural mapping was conducted in conjunction with systematic channel sampling of hand-dug pits and limited surface exposures; channel widths often being limited by extent of exposure. A total of 95 rock samples (87 channel samples and 8 grab samples) were collected from a 900 by 250 metre area at Heaven West. The actual limits of the zone have not yet been defined.
Mineralization at Heaven West is hosted in sulphide-bearing quartz veins and saprolitic and hydrothermally altered medium to coarse-grained monzogranite, assigned to the Parauari intrusive suite. Hydrothermal alteration includes sericite, silica, pyrite and minor chlorite. Observed veins ranged in thickness from 1 to 70 centimetres and areas with closely spaced veins show pervasive wallrock alteration. Structural interpretation indicates the presence of a complex brittle zone composed of four main structural systems within a poorly developed broad northwest trending shear zone which parallels the dominant structural orientation of the region. North and northeast structures which crosscut the northwesterly shearing host high-grade gold mineralization.
Serra da Abelha Target
As reported in the Company’s news release of May 14, 2007, the Serra da Abelha target is defined by an 800 by 250 metre wide northwest trending +100 ppb gold in soil anomaly. Anomalous gold in soil values range from 100 to 521 ppb Au and the anomaly is open to the northwest. Geological mapping and surface sampling is being conducted at Serra da Abelha prior to drill testing. Based on limited outcrops exposures, a similar geological and structural setting to the Heaven West area is recognized at Serra da Abelha.
2007 Exploration Program
The Company has commenced a Fall 2007 exploration program at Água Branca which will include geological and structural mapping, rock and channel sampling, grid based soil sampling and diamond drilling. Surface work is underway, with diamond drilling to commence in early October. The 2007 drill program is designed to provide an initial test of both the Heaven West and Serra de Abelha targets. Additional target areas may be tested based on the results of ongoing surface work.
Additional target areas at Água Branca include Jerimum, Carlinhos and Araguari. Geological mapping is ongoing and rock and grid-based soil sampling has been conducted at the Jerimum target; assay results are pending. Mapping and rock and soil geochemistry has commenced over the Carlinhos target. Similar exploration is planned for Araguari and other pre-selected geophysical targets. Power auger drilling equipment was recently moved to the Project and will provide additional information to define new drill targets.
Exploration at Água Branca is being managed by Talon’s VP Exploration, Mr. Paulo Ilidio de Brito (Member: AusIMM), who is a qualified person within the meaning of National Instrument 43-101. Mr. Ilidio de Brito, who is responsible for the technical material on this page, has verified the data disclosed, including the sampling, analytical and test data underlying the information.
