Work History
Staked as Hag cl (62794) in Jun/55 by A. Kulan, G. Dickson and W.B. Green, who optioned them to Stride Exploration and Development Company Ltd in Jun/58. Stride Exploration carried out geochemical sampling and geophysical surveying later that year. The claims were later optioned to Peso Silver Mines Ltd in Jun/62.
Restaked as Tara cl (82826) in Mar/63 by Canex Aerial Exploration Ltd; as Arpa cl 1-40 (Y31687) by C. Provencher and J.H. Boyce; as WM cl 1-2 (Y56061) in Jun/71 by W. Meilecke, who carried out hand trenching; and as WM cl 1-2 (Y69422) in Jul/73 by J. Mandaus.
Restaked as DG cl 1-56 (YA14944) in Apr/77 by G. Dickson, who carried out bulldozer trenching later in the year. Dickson optioned the claims to Canada Tungsten Mining Corporation Ltd in the spring of 1978, which carried out prospecting, reconnaissance and detailed geological mapping, geochemical rock, soil and stream sediment sampling, trenching and magnetometer surveying from 1978-81. The claims were transferred back to Dickson in Jan/86.
Can-Pro Development Ltd optioned the DG claims as part of a larger block of claims in the Dublin Gulch area in 1989. Ivanhoe Goldfields Ltd optioned Can-Pro's claims in 1991 and subsequently optioned them to Amax Gold (B.C.) Ltd, which in 1992 drilled 2 rotary holes (216.4 m); one each on DG cl 9 and neighboring Smokey cl 52. These two drill holes were part of a much larger drill program carried out on Dublin Gulch property.
Ivanhoe staked the adjacent Sec cl 1-124 (YB29877) in Jun/93, before being acquired by First Dynasty Mines Ltd in Aug/94. In 1995, First Dynasty and in 1996 its wholly owned subsidiary, New Millennium Mining Ltd carried out a major drilling program to outline a resource/reserve on the Eagle Zone (Minfile Occurrence #106D 025). The companies also carried out diamond drilling on Potato Hills (Minfile Occurrence #106D 026) to test for mineralization under the proposed heap leach pad area.
Restaked as Tin Dome cl 1-12 (YC02842) in Aug/2001 by B. Walden and K. Benson who carried out prospecting and rock geochemical sampling in 2001 and 2002.
Capsule Geology
The Dublin Gulch area is underlain by deformed clastic rocks of the Late Proterozoic to Lower Cambrian Hyland Group that have been intruded by Late Cretaceous Tombstone Plutonic Suite stocks, dykes and sills. Alteration and gold and tungsten mineralization is associated with the intrusions.
The early staking on Iron Rust Creek covered a transported limonite gossan in a creek draining weakly metamorphosed clastic rocks and schist. A galena vein is rumoured to have been exposed on the WM claims.
Prospecting and rock geochemical sampling in 2002 failed to locate the source of massive arsenopyrite float boulders discovered, 125 m southwest of this occurrence, in 2001. Sampling of silicified and pyritized siltstone from outcrop just west of the occcurrence did not detect any anomalous results.
