Capsule Geology
The area is underlain by a northeast-dipping sequence of Pennsylvanian to Permian age rocks, assigned to the Campbell Range succession. The Campbell Range succession was previously thought to be part of the Slide Mountain Terrane but recent mapping by Murphy and Piercey (1999, map) suggests that the succession is part of the Yukon-Tanana Terrane and that it represents the culmination of the transition from arc-rifting or back-arc extension to oceanic or back-arc marginal basin magmatism and sedimentation. The Yukon-Tanana Terrane hosts the neighbouring Wolverine (Yukon Minfile #105G 072) and other volcanogenic massive sulphide (VMS) deposits
Unit ]P Cs, the middle unit of the Campbell Range succession and the youngest unit exposed in the area, is composed of carbonaceous argillite, quartz sandstone, chert, and chert pebble conglomerate. In the northeast the unit passes into a Pennsylvanian limestone, unit ]P Cl. The upper unit, unit ]P Cb2 consists of foliated and tightly folded, coarse basaltic breccia, pillowed and massive basaltic lavas, gabbro, diabase and maroon and green chert. Pennsylvanian to Permian ultramafic rocks intrude all levels of the succession.
The area has been glaciated but bedrock on upper slopes is relatively well exposed with little or no till cover. The rocks strike northwesterly and dip apparently in a homoclinal fashion to the northeast at about 60 degrees. The rocks are regionally metamorphosed to sub-greenschist facies, characterized by epidote alteration and weak foliation sub-parallel to bedding. To the northwest gentle folds indicate the sequence occupies the eastern limb of a major fold. Lineations suggest a shallow plunge to the northwest.
The occurrence hosts two types of volcanogenic massive sulphide (VMS) mineralization One consists of small massive pyrite lenses, the other consists of larger disseminated and stockwork pyritic bodies. The pyrite lenses are narrow and likely rod shaped with limited strike length as they produce no conductive effects. The disseminated bodies are up to several hundred metres long and may be up to 30 m wide with weak to moderate conductive effects. Both styles of mineralization contain minor amounts of Cu, Zn, Ag and Au.
Poorly exposed beds of massive pyrite, 1.5 m thick, with minor chalcopyrite subcrop in Boulder and Welcome North Creeks. A grab sample from Welcome North Creek returned results of 0.167% Cu, 0.05% Zn, 0.63 opt Ag and 0.018 opt Au. Additional mineralization occurs in several gossanous areas underlain by siliceous and clay altered rock containing pyrite with minor chalcopyrite and brown sphalerite disseminated and in fractures.
Arbor Resources carried out a soil geochemical survey and analysed the samples for Cu, Pb, Zn, Au and Ag. Three areas with elevated Cu (> 100 ppm) values were identified in 1981. Anomalous Cu values (up to 6 000 ppm) were obtained over the gossan in Boulder Creek. Weaker anomalous values were obtained near Welcome North Creek and near a gossanous area south of Camp Creek. Weakly anomalous values in Zn roughly coincide with the three Cu zones. Ag, Pb and Au values are low.
Esso Minerals carried out 19 line km of HLEM and 18 line km of magnetometer surveys. The EM survey identified 5 conductors one of which in part coincident with the large gossan on Boulder Creek. The company also collected eleven silt samples from the three streams that cross the property. Boulder Creek returned the highest values of 500 ppm Cu, 2.3 ppm Ag and 10 ppb Au.
Of the three diamond drill holes drilled in 1981, hole 81-1, failed to intersect the massive sulphides in Boulder Creek but did cut a lower zone of disseminated and stockwork sulphide mineralization consisting of pyrite, with minor chalcopyrite and traces of sphalerite in a quartz-clay altered rock (tuffaceous sediment ?). Hole 81-2 from the same site, but angled 45 degrees further north, intersected 0.5 m of massive pyrite at the base of a maroon siltstone or argillaceous tuff bed. Below that was a layer of pillowed basalt followed by the same zone of disseminated and stockwork mineralization intersected in hole 81-1. The hole cut the zone sooner that expected suggesting that the zone is not stratigraphically controlled. Hole 81-3 was drilled to test a 1.5 m wide subcrop of massive pyrite in Welcome North Creek. It failed to intersect any sulphides.
In 1990, YGC re-examined the mineralized showings. The company determined that the mineralization probably belongs to the Besshi-type of volcanogenic massive sulphide deposits which typically occur within fine-grained clastic sedimentary rocks deposited after the cessation of submarine basaltic volcanism. The gossanous alteration zones that occur stratigraphically below the Boulder Creeks massive sulphide showing may represent hydrothermal feeder zones for the stratiform mineralization.
Reconnaissance soil sampling outlined three areas of elevated copper response. Two of the areas occur downslope of areas of known mineralization. The source of the third area was not determined. Prospecting uncovered several angular boulders of massive pyrite-pyrrhotite up to one metre in diameter in the bed of Boulder Creek, upstream from one of the previously discovered gossans. Selected samples from the boulders assayed from 0.44% Cu and 1.4 g/t Au to 2.06% Cu and 2.1 g/t Au. An occurrence of ferricrete was found in the bed of Welcome North Creek.
Atna¿s 1995 program generally confirmed earlier results obtained by YGC and others. Soil sampling outlined 4 areas anomalous in copper, and the HLEM geophysical surveys identified 4 conductors, all of which were related to either mineralized showings or gossans.
Two of Atna¿s 1996 drill holes were drilled to test the down-dip and strike continuation of the massive pyrite mineralization located on surface in Welcome North Creek. Both holes failed to intersect massive sulphide mineralization. The sequence exposed on surface, with the exception of the massive sulphides, was represented in both drill holes. Poor recoveries and faulting may be responsible for the absence of sulphides in one hole, where a 3 m washout with no core recovery occurred at the expected depth of the massive sulphide layer.
The remaining five holes tested sulphide mineralization in the Boulder Creek area. All five holes intersected either massive sulphides or zones of quartz-sericite-pyrite+/- chlorite stockwork up to 20 m thick. Mineralization consists primarily of sulphides of copper with lesser zinc, gold and silver within a sequence of mafic flows and breccia and is associated with maroon and oxidized fine-grained sediments. The best drill result down dip of the surface showing returned 1.2 m of 0.62% Cu, 0.15% Zn, 32 g/t Ag and 0.7 g/t Au. Drilling has defined a tabular massive sulphide layer with a down dip length of at least 130 m, a strike length greater than 53 m and an average thickness of 1.0 m.
Drilling in 1997 tested resistivity lows identified during geophysical resurveying of the central portions of the claim block. Hole Mon 97-8 intersected elevated Cu-Zn +/- Ag +/- Au in three semi-massive (>60%) sulfide zones consisting of 0.7 m of massive sulfides within maroon pelites at a volcanic-sediment break, a 9.7 m pyrite pseudo-breccia zone and a 0.9 m pyritic tuff layer. None of the intersections were of either economic grades or widths.
Cominco originally staked the Era claims to follow-up two anomalous silt samples reported in a 1987 government regional geochemistry survey. Samples from two adjacent streams approximately 1 km apart, returned Zn values of 2 445 and 2 510 ppm, with corresponding cadmium values of 12.6 and 10.5 ppm. Silt sampling carried out in 1995 returned several anomalous values for Cu, Zn and Ba. An airborne geophysical survey outlined several conductive zones.
Soil sampling completed in 1996 outlined two linear zones moderately anomalous in Cu and Ni on the east side of the claim block. Silt sampling of streams at the north end of the claim block returned 25 samples highly anomalous in Zn and Ni. Ground geophysics outlined several conductive (HLEM) trends and magnetic responses. Soil sampling completed in the northeast corner of the claim block in 1997 returned 6 samples with values >= 100 ppm Zn and Cd values up to 131 ppm. Samples surrounding these anomalies reported higher than background Zn.
