100% Ryan Gold
Location and Setting:
The Ida Oro Property is located approximately 90 kilometres east of Dawson City, and 25 km east of the Brewery Creek mine in the Dawson Mining District, Yukon Territory. The property is comprised of 269 contiguous mining quartz claims that covers an area of 5,625 hectares.
Dawson City is serviced by daily scheduled flights from Whitehorse. There is an all weather sealed road between Whitehorse and Dawson City. The Ida Oro property is reached by helicopter from Dawson City.
Geology and Mineralization:
The Ida Oro property is a significant Tombstone Suite intrusive hosted gold prospect well known within this mineralized belt, that has not previously been drilled.
The property is underlain by a sequence of Ordovician-Silurian Road River Group sedimentary rocks that have been intruded by Cretaceous quartz monzonite stocks. Within the claim block, the exposed Road River Group consists of interbedded black to green chert, black to grey argillite, graptolitic shale, quartzite, and rare chert pebble conglomerate.
The Road River sedimentary units have been intruded by a Cretaceous monzonite that are exposed as three stocks and several east-west trending related dykes. The resistant quartz monzonite form the prominent north-south ridge of the claim block and underlie the highest point found in the area. The stocks and dykes exposed on the Ida property have a strong east west (90° - 110°) trend that is the same structural and mineralized trend at both the Panorama Ridge and Brewery Creek properties to the west. All three properties lie along a 070° trend that extends from Brewery Creek through Panorama Ridge and on to the Ida property.
The main exploration target associated with Tombstone Suite intrusions is bulk tonnage low grade deposits similar to the Fort Knox deposit near Fairbanks, Alaska and Dublin Gulch north of Mayo, Yukon, as well as other well known similar deposits or occurrences in a belt that extends for over 2000 km across Yukon and Alaska.
The 'Tombstone Suite Intrusive Hosted Gold' deposit model is one of intrusive hosted gold, genetically related to a porphyritic granite stocks. The genesis of the 'Fort Knox' deposit is comparable to porphyry copper or porphyry molybdenum systems and as such the 'Fort Knox' deposit type may be classified as a 'porphyry gold' system (Hollister, 1991). Arsenopyrite-pyrite-pyrrhotite in quartz veins and fractures are found within the quartz monzonite stock and adjacent to it in cherty meta-sediments. Breccia and tourmaline rich zones are found in the quartz monzonite. Pyrite is disseminated locally within the stock and along with pyrrhotite is ubiquitous in the surrounding hornfels. The best gold grades have been obtained from samples of quartz sulphide veins along iron oxide stained and altered fractures and faults within the intrusion.
In August 2010 Ryan Gold initiated an exploration programme on its Ida Oro project that included a helicopter-borne magnetic and radiometric survey and a soil geochemical sampling programme.
The helicopter borne survey was conducted by Canadian Mining Geophysics (CMG Airborne). Flight lines at 100 m spacing, and totalled 1,170 km orientated north-south with 128.8 km of tie lines spaced at 1,000 m orientated east-west. The survey identified three intrusive bodies, one large and two smaller bodies located NW of the large intrusion.
A total of 5,490 grid Auger soil samples were collected by Ground Truth Exploration Ltd. of Dawson City, Yukon. The figure showing the compilation of gold in soils for 6,705 samples (1,215 samples collected in earlier campaigns) collected using auger sampling at 50 m spacing on 100 m spaced lines. This program confirmed a strong central gold-in-soil anomaly (>250 ppb Au) extending for 4 km in a north south direction and approximately 1 km in an east-west orientation. There is well defined coincident arsenic, antimony, mercury, copper anomalies. The soil geochemical anomalies are co-incident with a magnetic low (magnetic signal) within the main magnetic body as defined by the helicopter borne geophysics.
The company is planning the following exploration programme for 2011 on the Ida Oro project:
- Trenching programme over the main coincident soil geochemical and geophysical anomaly;
- Detailed mapping of the geology, alteration and mineralization within the coincident geochemical and geophysical anomaly;
- Drilling of the anomaly;
- Ridge and Spur sampling of the area outside the current grid;
- Regional mapping of the property.
