Sampling and Analysis and Security of Samples

Sample preparation and analysis of core samples taken by Talon were performed by SGS Lakefield-Geosol Ltda. ("Geosol"), an ISO 9000-2001 certified laboratory. Sample preparation procedures completed by the Geosol preparation laboratories based in Parauapebas and Itaituba were:

Sample pulps were air freighted to the Geosol analytical laboratory in Belo Horizonte, Minas Gerais State, Brazil and were analyzed for gold using a lead flux fire assay technique with an atomic absorption finish. Selected samples were subsequently sent for silver, lead, zinc analysis by ICP spectrometry using a multi-acid digestion technique. Abnormally high assays were re-analyzed by the laboratory. The detection limit of gold assays was 5 ppb Au. Coarse rejects from the Parauapebas and Itaituba laboratories were sent to the São Jorge exploration office and stored in the core shed. 50 g pulp rejects were also stored in the Talon offices in Rio de Janeiro.

Sample preparation and analysis of core samples taken by BGC, for the 2011/2012 campaign were performed by Acme Analytical Laboratories Ltd. of Vancouver, British Columbia ("Acme").

Acme performed each procedure for sample preparation and analysis, as follows: (i) crush split and pulverize 500 gram drill core to 200 mesh; and (ii) fire assay fusion Au by ICP-ES on 50 gram charges.

Core was stored in a locked and secure core shed. After logging, core samples were marked for splitting and sampling by BGC geologists. Core sample intervals were measured and collected by BGC technical staff. Each core sample was placed in a doubled plastic bag and with two sample tags. Each bag was closed with a uniquely numbered plastic seal that was tamper proof. Seal numbers, sample numbers and sample intervals were recorded by BGC. Sample bags were collected for shipping in rice bags with each rice bag closed with a numbered plastic seal. Samples were stored in the BGC core shed until transported by truck to the Acme preparation laboratories in Itaituba in Pará state. The referred laboratory is 320 km by road from the São Jorge Project. After samples were received by the lab, seal numbers and sample numbers were reported to BGC for confirmation.

Quality control data from the RTDM period was not available for analysis in connection with the São Jorge Project as it had not been located.

Quality control samples consisting of coarse duplicate rejects, blanks and standards were inserted in the sample stream by Talon and BGC to monitor the quality of the analytical results.
