The Eagle Gold-Silver Property

The Eagle Property consists of eight mineral tenures comprising 4543.3 hectares and is situated 95 km northwest of Fort St. James, British Columbia. Access to the property is by road from Fort St. James to Tchentlo Lodge at the west end of Tchentlo Lake, a distance of 110 kms. From here, the property is reached by a one-hour boat trip east along Tchentlo Lake for 23 km. Local tote roads and trails, now overgrown, lead to various points on the property.

In the fall of 2009, Rich Rock purchased the property from Eagle Peak Resources Inc. (“Eagle Peak”), an associated company.

Three areas of copper mineralization have been identified along a northwest-trending zone within the Hogem Batholith, known as the Vector, Mid and Nighthawk Zones. Mineralization here consists of chalcopyrite, pyrite, malachite and minor azurite along fractures and shear zones. The Gibson gold-silver prospect lies in hornfelsed Takla sediments near the Hogem contact 400m southwest of the Nighthawk Zone.

Historical Exploration

The property has received considerable exploration work since its discovery in 1966. This work comprised extensive geochemical, geophysical and drilling programs conducted by Noranda Exploration in 1989-1991 and Birch Mountain Resources in 1996. This work identified the Gibson Zone in the southwest part of the property as a significant gold-silver-base metal target.

A number of mineralized zones have been found on the Eagle Property and are referred to as the Gibson Zone, the Nighthawk Zone, the Vector Zone and the Mid Zone (Stewart 1990). The latter three comprise the Main Zone, which has received most of the exploration work and drilling to date.

A compilation in 2007 commenced with a thorough process of digital data capture and integration of all available historical data from ARIS reports. Data compiled from ARIS reports included:

  • 23 drill holes, including lithology logs and assays totalling 3322 meters
  • 3 geological outcrop maps
  • 2 ground magnetics surveys
  • 3 induced polarization surveys
  • Approximately 6000 geochemistry samples
Exploration 2009-2010

Dr. Peter Fox Ph.D., P.Eng., completed a compilation (see figures 2-3) of geology and various sampling campaigns completed in prior years.

In 2010, Rich Rock Resources contracted Canadian Mining Geophysics Ltd (CMG) to conduct an airborne radiometric survey over part of the Eagle property.

CMG completed 100 km of helicopter-borne magnetic gradiometer, VLF-EM and radiometric surveys. The survey lines were oriented NE-SW across the regional structural trend and covered the gold-silver mineralization primarily on the Gibson Zone, the chief target identified by prior work.

The CMG airborne survey identifies a number of regions of interest that are recommended for follow-up. These features exhibit the correspondence of near surface magnetics, cross-cutting features and elevated radioactivity. The areas should be examined for surficial evidence of mineralization and considered for follow up.

In 2010, Rich Rock retained B.J. Price Geological Consultants Inc. and Mitchell Geological Services Inc. to complete a National Instrument 43-101 Technical Report on the Eagle Property. To view this report click here.



Conclusions from Eagle Gold-Silver Property Technical Report

The Eagle Property has at least five mineral showings, the Vector, Mid and Nighthawk Zones, the Gibson Zone and the Phil 20 prospect.

The Gibson Zone is likely a mesothermal shear zone in Takla Group age volcanics with strong clay and sericite alteration bearing significant tenors in zinc, lead, gold and silver. The vein structure strikes northwest, is some 4.5 metres thick, 400 metres long and is open along strike to the northwest and southeast.

Prior drilling at the Gibson Zone has established a large clay-sericite-silica alteration zone associated with the mineralized zone and a zinc-lead (Au,Ag) soil anomaly lying along strike to the northwest for 900 metres providing a target some 1500 metres long. All 1991 Noranda drill holes intersected significant sections of intense claysericite-quartz alteration and associated pyrite, galena and sphalerite mineralization. One of the better intercepts, among others of lower value, in Hole 91-5 returned 4.3 metres of 6.77 gpt Au, 1828 gpt Ag, 2.69% Zn and 3.34% Pb, and these grades were validated by resampling the remaining core.

Incidentally, the Gibson Zone and many of the shears and mineralized zones in the Hogem batholith are northwest trends parallel to the Pinchi Fault which lies some 15 or 20 kilometres to the west and also appears to cross the contact of the contact of the Hogem Batholith with the Takla Group as the zone is projected to the north. The Gibson Zone has gold and silver grades that are encouraging and the mineralized structure is worthy of additional exploration with the goal of defining an underground mineable high-grade gold silver deposit.

The Main Zone showings, comprising the Vector, Mid and Nighthawk are typical alkalic porphyry style showings, that as yet are narrow. Most have not been tested at depth. Typical intercepts from 1991 are:

Nighthawk Zone:
EA-91-06: 27.28 m of 0.87% Cu, 0.32 gpt Au and 3.85 gpt Ag.
EA-91-07: 15.74 m of 0.69% Cu, 0.20 gpt Au and 2.19 gpt Ag.

Vector Zone:
EA-91-12: 17.9 m of 0.82% Cu, 0.47 gpt Au and 4.11 gpt Ag.
EA-91-13: 20.2 m of 0.56% Cu, 0.29 gpt Au and 2.84 gpt Ag.

Later drilling by Birch Mountain was incompletely sampled and no significant intercepts of gold and silver were noted in the six holes completed (2 at Vector and 4 at Nighthawk). However, location of the drill holes and azimuths may not have been optimum to test the mineralized zones exposed on surface and intercepted earlier by Noranda.

The Main Zone and subsidiary Vector, Mid and Nighthawk Zones have potential for one or more Mt. Polley type high grade copper-gold deposits which in aggregate could be of economic interest. However, the main goal in this area would be to explore and define a larger low-grade copper-gold deposit similar to the Mt. Milligan deposit. The narrow zones as outlined above in the two zones are worthy of deeper drilling. The Mid Zone has never been drill-tested.

Recommendations from Eagle Gold-Silver Property Technical Report

The Gibson Zone is an attractive gold-silver target and warrants further work. This should include detailed surface mapping, excavator trenching, geochemical sampling and geophysical surveys (deep IP) along the strike of the 1500m-target zone. This work would be followed by diamond drilling, to extend the silver gold mineralization outlined previously.

Similarly, for the Main (copper-gold) Zone, new geological mapping is suggested for all three subzones, to be followed by deep IP surveys, and deeper drilling with the goal of defining broader open-pit mineable copper-gold deposits.

Phase I
A two-phase program is proposed to explore the Eagle Property. The first phase would involve:

  • Investigating the construction of a temporary camp at the old Noranda Campsite
  • Clearing access trails and safe helipads at all the zones, using an excavator or small bulldozer
  • Using ATV’s for access
  • Mapping all showings
  • Relogging the well-preserved drill core and re-sampling where required
  • Finding past grids and using them to relocate past geochemical anomalies
  • Backhoe or excavator trenching the Gibson gold-silver mineralized structure
  • Extending the zone north-westward using trenching and geochemistry (auger soil samples)
  • Investigating the showings (Phil and Tch) on the newly acquired claims
  • Investigating the new porphyry target resulting from the 2010 geophysical survey
  • Using a deep IP (Titan 24) or 3-D Ip method on all the showings to define drill targets

Phase II Program

A second phase of exploration, including diamond drilling in all showing areas would be dependent on the success of the first phase. A quality assurance and control program is suggested to involve re-sampling some or all of the mineralized sections, use of standards, blanks and duplicate samples.
