12/18/2017 (M A Puumala) - Modified excerpt from Institute on Lake Superior Geology 2012, v. 58, pt. 2, p. 56-66. The Creek Zone is located approximately 2 km northeast of the Roby pit in the northeastern nose of the Mine Block Intrusion (MBI), near the contact with the north Lac des Iles Intrusive Complex. Surface trenching has exposed the main portion of the Creek Zone in an area 90 m long by 10 to 40 m wide. It is dominated by low-sulfide breccias that have intruded the varitextured gabbro rim of the MBI. The breccias consist of approximately 90% gabbronorite clasts and only approximately 10% melanogabbro matrix. Unlike the Roby Zone, mineralization is not dominantly hosted by the breccia matrix but seems to occur within the pegmatitic gabbronorite. Prospecting, mapping, trenching, sampling and limited diamond drilling of the Creek Zone have indicated limited mineralized potential.
12/18/2017 (T Pettigrew) - Poddy palladium and disseminated base metal sulphide mineralization is associated with localized sulphide-bearing magmatic breccia, varitextured gabbro, norite and north-trending and east-northeast-trending faults and shear zones. Surface trenching has exposed a showing at which palladium enrichment, locally reaching 2 g/t Pd, is associated with a pegmatitic gabbro containing sparse blebs of disseminated sulphide mineralization. The most notable mineralized drill intercept was reported from drillhole 08-020, which intersected 25 m with an average palladium grade of 2.47 g/t Pd at ~100 m depth from surface and in a noritic unit containing minor disseminated sulphide mineralization. The Creek Zone features the general trend of increasing Pd/Pt ratio with increasing Pd abundance that characterizes both the Roby and Offset Zones (Buss et al., 2017). Results from the 2018 drill program include: DDH 18-006: 40.1 m @ 2.14 g/t Pd, 0.27% Cu, 0.22% Ni, including 1.0 m @ 41.40 g/t Pd, 0.27% Cu, an 0.86% Ni; and DDH 18-007: 47.0 m @ 2.36 g/t Pd, 0.15% Cu, 0.15% Ni, including 13.0 m @ 5.18 g/t Pd, 0.22% Cu, and 0.25% Ni (North American Palladium Feb 11 2019 press release).
