There are three styles of gold occurrences identified on the Property, including: 1) intrusive-hosted sulfide disseminations and sulfide-quartz stockwork veinlets (such as the Dolphin gold deposit); 2) auriferous sulfide-quartz veins; and 3) shear-hosted gold-bearing veinlets. All three types are considered to be part of a large-scale intrusive-related gold system on the Property.

Instrusive-Hosted Sulfide-Quartz Veinlets
Intrusive-hosted, auriferous sulfide disseminations and auriferous sulfide-quartz veinlets (0.1-5 mm) within the Dolphin stock are spatially associated with the highest gold grades within the Dolphin gold deposit. Gold also occurs with disseminated euhedral arsenopyrite (1 to 5 mm) which appear to be an earlier, higher temperature mineralization event (McCoy and Olson, 1997). Gold mineralization within the deposit also occurs as mineralized fault gouge enriched with sulfides, sulfide-rich veins, and locally as narrow sulfide-quartz veins <6 inches thick; however, these comprise a relatively small portion of the total gold resource.

Gold within the Dolphin gold deposit occurs largely as inclusions in sulfides, and locally as visible grains, within the sulfide-quartz veinlets. Pyrite and arsenopyrite is the most common sulfide mineral, although stibnite, lead-antimony sulfosalt minerals, tetrahedrite, scheelite, galena and sphalerite occur locally. McCoy and Olson (1997) identified two distinct varieties of arsenopyrite in the Dol ........

Due to the pit containing both sulfide and oxide material, there will be two methods of processing.

Oxide material will be mined and processed exclusively for the first eight years of the mine production. A small amount of sulfide material will be mined before year eight; this sulfide material (approximately 800,000 tonnes) will be stockpiled until the end of mine life. In year nine, the sulfide material comes online for production. Mining of the oxide material will continue through year 14 of the 24-year mine life. Mining of sulfide material will continue from year nine through the end of the 24 -year mine life.

During production, both oxide and sulfide material will be transported from the pit to the primary crusher located near the pit exit. After primary crushing, oxide and sulfide material will be transported by conveyor to its respective process area. The oxide will be leach processed in an area to the southeast of the pit, while the sulfide will be processed northwest of the pit.

Waste will be hauled by truck to the Mine Rock Storage Facility (MRSF). The MRSF has been designed to permanently contain the overburden and waste material associated with the pit. The current MRSF design, located to the northeast of the pits, is built around the hill. The MRSF was designed with a buffer around the nearby creeks. The total MRSF design will contain 100% of the expected waste material planned to be generated - approximately 239 million tonnes o ........
