Shillington Property
Location: 85 kilometres south east of Timmins
Minerals: Gold and Copper
Ownership: 100% Golden Chalice
Background
 Located approximately 24 kilometers northwest of Elk Lake, Ontario
The property is south of the Matachewan gold camp and northeast of the famed Gowganda silver camp, second only to the Cobalt area in terms of its silver production.
Earlier workers in the area have reported significant gold and silver mineralization occurring within altered Huronian sediments, diabase dikes and syenite.
The Lavigne Lake Silver Mining Company reportedly had zones containing 1.25 opt gold and 20 opt silver over 30 feet, with another zone averaging 14 pennyweights (0.7 opt) gold over 20 feet for great length. Whereas the Chicago-Gowganda property had 0.35 opt gold over 20 feet on the 185 foot level of the mine. The Stibbard-Morrison Property was reported to be the best of the properties, however no assays were given. The exact locations of the mined zones are not known. They were last worked in 1911.
Combined ground magnetometer and VLF surveys have delineated E-W anomalies within and proximal to northwest trending structural corridors that coincide with a number of historical trenches and shafts dating back to the early 1900's.
Drilling to explore for the Lavigne Lake zone intersected a brecciated zone of quartz stockwork with patches of semi-massive chalcopyrite hosted within hematitic and potassic altered greywackes. The quartz breccia zone dips subvertically to the north. One zone returned a value of 1.50% Cu over 10.30 meters from 25.0 to 35.30 meters, including 1.98% Cu over 3.4 meters from 25.60 to 29.0 meters. Another hole intersected 2.0% Cu over 6.0 meters.
Geology, and Mineralization
This new discovery occurs within an area underlain by the Round Lake Batholith that has received limited exploration.
Ontario Government's regional lake and stream sampling program has identified a N-S gold anomaly in sediments running down ice for over 40 km from Shillington Township.
Lake water sampling has identified an E-W string of lakes just south of Shillington Township that have coincidental gold and cobalt anomalies in water samples. This association may be indicative of a porphyry gold system.
The newly discovered E-W trending mineralized copper zones in Shillington Township are open along strike and at depth.
Copper mineralization is locally associated with hematite alteration (non-magnetic iron oxide). Gold may be associated with magnetite mineralization (magnetic iron oxide).
The Upper Beaver mine in Kirkland Lake has a magnetite rich zone with 1 to 2 opt gold and over 1% copper within volcanics, sediments and syenite. According to one of the geologists, copper occurs with hematite, whereas the gold, with or without copper, occurs in magnetite rich zones.
Although the Shillington rocks are a different age, the rocks described that contain gold mineralization could be similar in chemistry to the Upper Beaver.
A magnetite rich granite, or quartz rich diabase, intrusive has been discovered by surface mapping at Shillington. The intrusive intrudes the older Huronian sediments that host the copper and possible gold mineralization. This intrusive or possibly an associated syenitic phase, could host a porphyry gold-copper deposit. There is also potential for an IOCG (iron-oxide-copper-gold) deposit.
Given the potential large nature of this new discovery, Golden Chalice Resources has completed an extensive staking program covering more than 125,000 acres of additional favorable geology.
Geotech was contracted to fly a 1300 km VTEM airborne survey to outline additional mineralized zones near surface and at depth on the property.
Diamond drilling to test various ground geophysical survey anomalies and geochemical anomalies did not intersect the gold-silver mineralized zones that were reportedly mined in 1911. However, the drilling did intersect geology similar to the geology that was described as hosting the gold-silver mineralization in 1911. Further drilling in areas with similar geology is warranted.
Next Steps
Although initial drilling was unable to confirm reported historical gold-silver mineralization, the holes may not have drilled the structures with gold mineralization. There is very limited information about the exact location of the gold zones that were last worked in 1911.
There are many magnetic and non-magnetic anomalies and structural features identified by the geophysics that remain to be tested.
The copper breccia zone with hematite alteration and quartz flooding may be an indication of the potential for an IOCG or porphyry gold-copper deposit at depth. Interpretation of the airborne VTEM magnetic suggests the presence of large circular magnetic ring-like structures. These structures appear to be associated with magnetic anomalies at depths below 250 vertical metres. GCR is planning additional geophysical surveys or drilling to test the potential for IOCG or porphyry gold-copper deposits at depth on the Shillington Property
