Conrad Zone

Highlights

• Conrad Zone contains 1,290,000 ounces of gold at 4.15 g/t Au (in 9.7 Mt)
• Completed 54,609 m in 134 diamond drill holes
• Highlight diamond drill hole intersected 42.93 m of 18.44 g/t gold in OS-12-114
• Mineralization at Conrad is hosted within silty limestones and is concentrated along fold hinges, faults and lithologic contacts
• Conrad Zone is open in all directions

Conrad Mineral Resource	Gold Cut-Off	Tonnes	Grade (Au g/t)	Gold (oz)
Pit-Constrained	1.30 g/t	6,487,000	4.00	835,000
Underground	2.60 g/t	3,174,000	4.46	455,000
Total Inferred Mineral Resource		9,661,000	4.15	1,290,000

Carlin-type mineralization at the Conrad Zone is contained within several structural and stratigraphic settings. In the Conrad Upper Zone, gold mineralization occurs along the stratigraphic contact between limestone and an overlying pyritic siltstone cap unit where the thickest mineralization occurs along the crest of an anticlinal fold. The Upper Zone has been continuously traced by shallow drilling over a strike length of 800 m between sections C100E and C900 E. Mineralization at the Upper Zone remains open along strike.

Mineralization at the Conrad Middle Zone is characterized by strong alteration and mineralization within multiple stacked, flat-lying bodies proximal to a laterally extensive, near vertical siltstone-limestone contact. Only 300 m of the presently known 800 m long favourable siltstone-limestone contact has been tested. Mineralization at the Middle Zone remains open along strike and at depth.

Osiris Zone

Highlights

• Osiris Zone contains 122,000 ounces of gold at 4.21 g/t Au (in 901,000 t)
• Completed 17,960 m in 67 diamond drill holes
• Highlight diamond drill hole intersected 65.20 m of 4.65 g/t gold in OS-10-001
• Mineralization at Osiris is mostly stratabound and is open along strike and at depth

Osiris Mineral Resource	Gold Cut-Off	Tonnes	Grade (Au g/t)	Gold (oz)
Pit-Constrained	1.30 g/t	474,000	4.61	70,000
Underground	2.60 g/t	427,000	3.79	52,000
Total Inferred Mineral Resource		901,000	4.21	122,000

The Osiris Zone lies between the Conrad and Ibis zones, and similar to both, gold mineralization is best developed in the hinge or crest area of an anticline fold. Drilling has also outlined stratabound gold mineralization over a 900 m strike length along the east and west limbs of the fold and in the hinge of the fold. Higher grade drill intersections are located in the hinge area where Hole OS-10-001 intersected 65.20 m of 4.65 g/t gold. Strong exploration potential exists on the west limb of Osiris towards the north where only wide-spaced shallow intersections have been drilled.

Sunrise Zone

Highlights

• Sunrise Zone contains 137,000 ounces of gold at 5.07 g/t Au (in 840,000 t)
• Completed 8,408 m in 34 diamond drill holes
• Highlight diamond drill hole intersected 26.70 m of 12.95 g/t Au in OS-18-273
• Mineralization is hosted in a silty limestone and is dominantly structurally controlled
• Sunrise is open to the east and at depth

Sunrise Mineral Resource	Gold Cut-Off	Tonnes	Grade (Au g/t)	Gold (oz)
Pit-Constrained	1.30 g/t	309,000	4.23	42,000
Underground	2.60 g/t	531,000	5.53	95,000
Total Inferred Mineral Resource		840,000	5.07	137,000

The Sunrise Zone is located 300 m east of the Osiris anticline hinge zone. Mineralization at Sunrise occurs as sub-parallel tabular bodies that dip steeply south. Gold mineralization at the top of Sunrise discovery hole (OS-12-173) intersected intensely decalcified limestone adjacent to a steeply dipping fault. This hole was collared directly within mineralization and returned 14.86 m of 10.54 g/t gold. Drilling to the east and west of OS-12-173 in 2013 extended the strike length of mineralization to 215 m and to an open depth of 350 m from surface. Exploration potential within Sunrise exists at depth.

Ibis Zone

Highlights

• Ibis Zone contains 136,000 ounces of gold at 4.33 g/t Au (in 978,000 t)
• Completed 6,575 m in 26 diamond drill holes
• Highlight diamond drill hole intersected 38.10 m of 3.33 g/t gold in OS-11-040
• Mineralization is dominately stratabound and is drilled over a 200 m strike length
• Open along strike to the east, northwest and at depth

Ibis Mineral Resource	Gold Cut-Off	Tonnes	Grade (Au g/t)	Gold (oz)

Underground	2.60 g/t	203,000	4.27	28,000
Total Inferred Mineral Resource		978,000	4.33	136,000

The Ibis Zone (formerly called Isis East) is located 550 m southwest of the Sunrise Zone within the 12 sq/km Osiris cluster. Gold mineralization is stratabound and localized in the crest of an anticlinal fold at or near the favourable contact between dolomite altered limestone and underlying silty limestone. Mineralization has been intersected over an unfolded strike length of 230 m and remains open for extension below the current tier of drilling. Two soil geochemical anomalies located to the east and west of the currently drilled areas that have not been fully-tested.
