The drill program and sampling protocol is managed by Southern Arc under the supervision of Andrew Rowe. The diamond drill holes are drilled at PQ, HQ and NQ sizes depending on hole depth and core recovery to date has averaged 98.0%. Half core is cut by rock saw and is generally sampled using nominal 1-metre intervals; however, sample intervals are varied according to geological contacts and have ranged between 0.2 to 2.5 metres in length. Three quality control samples (one blank and two standards) are inserted into each batch of 40 samples. The half core samples are securely transported from the project site to the Intertek Testing Services ( ITS ) sample preparation laboratory in Sumbawa Besar via private truck hired by Southern Arc. Sample pulps are then sent to the ITS Jakarta laboratory by ITS. Gold is analysed by fire assay with AAS finish and a four-acid digestion with ICP-MS finish is used to analyse a full suite of elements including silver and base metals. ITS is one of the world s largest product and commodity testing, inspection and certification organizations. The Jakarta laboratory is ISO 17025 accredited and employs a Laboratory Information Management System for sample tracking, quality control and reporting.

Qualified Person The technical information in this document has been reviewed by Southern Arc s Executive Vice President, Andrew Rowe, B. App. Sc. Geology, MAusIMM. Mr. Rowe has over 18 years of international mineral exploration experience throughout Southeast and Central Asia and Australia. During this time he has held such positions as Principal Geologist Feasibility Studies, Senior Geologist and Consulting Geologist. The technical information in this document has also been reviewed by Southern Arc s President & Chief Operating Officer, Dr. Mike Andrews, PhD, FAusIMM, who has sufficient experience relevant to the style of mineralization under consideration and qualifies as a Qualified Person as defined by National Instrument 43-101. The drill program and sampling protocol is managed by Southern Arc under the supervision of Andrew Rowe. The diamond drill holes are drilled at PQ, HQ and NQ sizes depending on hole depth and core recovery to date has averaged 98.0%. Half core is cut by rock saw and is generally sampled using nominal 1-metre intervals; however, sample intervals are varied according to geological contacts and have ranged between 0.2 to 2.5 metres in length. Three quality control samples (one blank and two standards) are inserted into each batch of 40 samples. The half core samples are securely transported from the project site to the Intertek Testing Services ( ITS ) sample preparation laboratory in Sumbawa Besar via private truck hired by Southern Arc. Sample pulps are then sent to the ITS Jakarta laboratory by ITS. Gold is analysed by fire assay with AAS finish and a four-acid digestion with ICP-MS finish is used to analyse a full suite of elements including silver and base metals. ITS is one of the world s largest product and commodity testing, inspection and certification organizations. The Jakarta laboratory is ISO 17025 accredited and employs a Laboratory Information Management System for sample tracking, quality control and reporting.
