Errington-Vermillion Project November 2014
Deposit Location and Property
Errington-Vermilion: A rich history • The Errington-Vermilion deposits are located in the world renown Sudbury « Nickel » Basin, in Ontario. Both deposits were discovered in the 1920’s. • The Errington underground development began in 1924 and ended in 1928; it included three shafts and 7,925 metres of lateral development to a vertical depth of 457m. A total of 129,713 tonnes of ore were produced from Errington; • The Vermilion underground development occurred between 1952 and 1957 and included a 409m shaft and lateral development on 8 sub-levels totalling 5,073m. A total of 22,172 tonnes of ore were hoisted at Vermilion and stockpiled circa since 1958. The stockpile was shipped to Kidd Creek for processing in 1992.

Tailings Storage Facility
Tailings Storage Facility – Proposed Storage Locations Six alternatives have been considered for tailings (and potentially-acid-generating waste rock) storage, including three different tailings storage strategies (Knight Piésold 2014). These alternatives were: Option 1: A valley impoundment for storage of a conventional tailings slurry, located approximately 750 m south of the proposed ore concentrator; Option 2: A dry stack impoundment located approximately 400 m north of the proposed ore concentrator; Option 3: A dry stack impoundment located approximately 1,100 m west of the proposed ore concentrator; Option 4: A valley impoundment for storage of a conventional tailings slurry located approximately 1,800 m south of the proposed ore concentrator; Option 5: A paddock impoundment for storage of a conventional tailings slurry located approximately 1,600 m west of the proposed ore concentrator; and Option 6: A paddock impoundment for storage of a conventional tailings slurry located approximately 3,000 m east of the proposed Plant Site. By carrying out a multi-criteria analysis that considered environmental, socio-economic, technical and economic factors, a preferred alternative has been identified. The multi-criteria analysis used a three-tiered approach, in which weightings were applied to each tier (i.e., categories, criteria and indicators).

3 On-going Environmental Studies
A number of Baseline Studies have been conducted at the Errington site including: Due to the change in project scope, many of the previous baseline studies require additional study • Hydrology • Surface water • Hydrogeology • Fisheries • Hydro geochemical • Geochemical • Species at risk assessment • Archeological • Benthos • Sediment
Baseline Work Completed in 2014 • Geochemistry • Reviewing tailings humidity cell chemistry data • Water Quality • Surface water and sediment quality sampling (1 st round) • Hydrology • Contacted Domtar and NDCA for information • Installed data loggers and taken 1 st round of flow measurements • Hydrogeology • Wells installed • Terrestrial ecosystem • Completed baseline field program • Basking turtles (none), whip-poor-wills (none), marsh, water & breeding birds surveys • Vegetation surveys • Soil and vegetation sampling for metals analysis
Baseline Work Completed in 2014…/ • Aquatic ecosystem • Obtained MNR fish collection permit • Completed summer baseline field program • Aquatic Habitat mapping in TSF • Fish Habitat mapping and bathymetry in eastern end of Vermilion Lake, Vermilion River below Stobie Dam/lower Whitson River, and TSF • Fish, sediment and benthos collection • Noise/Light/Air • Noise/Light preparing for field work at end of September, weather permitting • Air contacting external agencies for existing baseline information • Aboriginal Participation Program • Successful program; good feedback from participants • Whitefish Lake FN Representative terminated contract early • Sagamok Representatives participate when available
