Target: The target at Lisburne is a major sedex zinc-lead-silver deposit similar to the Red Dog mine located approximately 90 mi (145 km) to the southeast.
Location and Setting: The Lisburne project is located in the Lisburne Hills of the Western Brooks Range in northwestern Alaska approximately 136 mi (220 km) northwest of Kotzebue. The project area is located on the Lisburne Peninsula which is bordered by the Chukchi Sea.
Land Status: The Lisburne property consists of 83 State of Alaska mining claims in four blocks totaling approximately 5,300 hectares.
Geology and Mineralization: The geology of the Western Brooks Range is characterized by multiple geologic terranes commonly occurring as stacked thrust fault sheets. A series of Mississippian to Devonian submarine sedimentary rock units, occurring within several of the terranes, regionally host numerous massive sulfide, vein breccia and vein breccia/disseminated zinc-lead-silver deposits and occurrences. The Red Dog mine, located in the western extent of the Brooks Range, is one of the premier zinc deposits in the world with reported probable reserves, as of December 31, 2013, of 45.4 MTonnes averaging 15.8% Zn, 4.1% Pb, 72.6 g/t Ag and an additional indicated resource of 7.5 MTonnes averaging 25.7% Zn, 6.9% Pb, 137.0 g/t Ag (Teck Resources Annual Information Form dated March 3, 2014). Mineralization at Red Dog typically occurs as shale-hosted massive sulfide bodies thought to have developed through a combination of SedEx and replacement processes. The shale-rich Mississippian Kuna Formation, part of the Endicott Group, hosts the major ore bodies.
The geology at Lisburne Hills is dominated by carbonate rocks of the Mississippian Lisburne Formation. Regionally, the Lisburne Formation statigraphically overlies the Endicott Group suggesting potential for the occurrence of Mississippian shale units and possible SedEx-style massive sulfide mineralization below this unit. Stream sediment samples collected by the United States Geological Survey on the project site locally include anomalous zinc and barium values.
Proposed Exploration Program: Millrock believes the Lisburne project has potential for the discovery of a major zinc-rich massive sulfide ore deposit. Recommended exploration programs include regional and detailed geologic mapping to define stratigraphy and determine possible zones of near surface favorable host rocks. Geochemical sampling and select geophysical surveys may be warranted in conjunction with geologic mapping in order to define potential drill targets.
Agreement and Terms: The Lisburne claim blocks are wholly-owned by Millrock. The Company is currently seeking potential joint venture partners for the project. If desired, Millrock can serve as operator on behalf of an earn-in partner.
