Eagle Hill Exploration Finds Additional High-grade Gold Mineralization Along Strike and at Depth, and Extends Zone 27 with Drill Intersections Including 11.2 g/t Over 37.3 Metres and …
February 12, 2014 (Source: Marketwired) — Eagle Hill Exploration Corporation (TSX VENTURE:EAG) (OTCQX:EHECF) (“Eagle Hill” or the “Company”) is pleased to release the final assay results from its Fall 2013 drill program at the Windfall Lake Gold Project (“Windfall Lake”). Eagle Hill completed a total of 28,107 metres of diamond drilling in 78 drillholes between September 12 and December 20, 2013, with the objective of expanding the known mineral resource.
Highlights of the latest assay results are shown in Figure 1 and summarized in Table 1. Additional assay results from the Fall 2013 drill program were previously released on November 5 and December 19, 2013.
The drill program was focused in three areas: testing a large, sparsely drilled anomaly to the southwest of the Main Zone, drilling lateral extensions of known gold lenses within the Main Zone, and testing the extension of mineralization at depth below the non-mineralized Red Dog intrusion (“Red Dog”). Eagle Hill also completed a hole-to-hole Induced Polarization (“IP”) survey to identify anomalies below Red Dog, and the first surface IP survey in the south part of the property where surface exploration had identified NE-trending lineaments similar to the Main Zone.
Highlights of Fall 2013 Drill Program
- Expanded Zone 27 by 40 metres up-plunge, for a total known strike of 800 metres
- Expanded Mink Lens 50 metres down-dip and 60 metres to ENE, for a total known strike of 500 metres
- Confirmed continuity of mineralization below Red Dog
- Confirmed extension of mineralization to the southwest of the Main Zone
- Down-hole IP survey showed additional potential below Red Dog
Southwest of Main Zone
The first 11 holes (4,821 metres) in the Fall 2013 drill program tested geophysical anomalies southwest of the tested limit of the Main Zone gold mineralization. The Company drilled three sections, stepping out 150, 300 and 500 metres along strike. Each section intersected significant gold mineralization, confirming the potential to extend the known gold resource in this direction.

Eagle Hill then drilled an additional 3,552 metres in seven drillholes and one wedge to follow up on drillholes EAG-13-472 (6.58 grams per tonne (“g/t”) gold over 3.5 m) and EAG-13-478 (3.01 g/t gold over 10.2 m) (see Eagle Hill press release dated November 5, 2013). This further drilling returned the following encouraging intersections:
|Section 1875||EAG-13-506||16.7 g/t gold over 1.0 m from 49.0 m|
|Section 1800||EAG-13-523||28.7 g/t gold over 0.4 m from 28.7 m|
|Section 1825||EAG-13-524||9.1 g/t gold over 0.9 m from 435.9 m|
These results further underscore the potential to expand the deposit to the southwest. Eagle Hill plans to drill additional infill holes in 2014 to the southwest of the Main Zone to identify a mineral resource in this area.
Main Zone Extensions
A total of 47 holes for 18,391 metres were drilled in the Main Zone to test for extensions of the major resource lenses (the Zone 27, Caribou, Mink and Mallard zones). Drilling confirmed the continuity of gold mineralization in higher-grade shoots and more specifically in Zone 27, which hosts the bulk of the mineral resource at Windfall Lake.
In Zone 27 (Figure 2), a number of drillholes were successful at expanding its known dimensions both to the southwest and up-plunge. Highlight intervals include:
|Section 2075||EAG-13-528||3.3 g/t gold over 22 m from 25.0 m|
|inc.||28.0 g/t gold over 1.7 m from 26.0 m|
This intersection expands Zone 27 by another 40 metres to the southwest and upward.
|Section 2175||EAG-13-527||415.7 g/t gold over 7.8 m from 226.2 m|
|inc.||1,196 g/t gold over 2.7 m from 229.6 m|
|inc.||6,070 g/t gold over 0.5 m from 231.0 m|
This intercept increases the high-grade lower portion of Zone 27 by another 40 metres up-plunge.
|Section 2300||EAG-13-512||3.9 g/t gold over 15.0 m from 292.0 m|
|inc.||19.4 g/t gold over 2.5 m from 304.0 m|
|Section 2675||EAG-13-511||6.3 g/t gold over 8.1 m from 671.0 m|
|inc.||48.2 g/t gold over 0.8 m from 675.0 m|
In addition, Eagle Hill continued to intersect high-grade gold mineralization in the Mink Lens, located between the Caribou Lens and Zone 27. The Mink Lens is smaller than Zone 27 but accounts for approximately 10% of the current mineral resource at Windfall Lake. The following intervals extended the known dimensions of the Mink Lens:
|Section 2650||EAG-13-513||11.0 g/t gold over 4.7 m from 661.3 m|
|Section 2825||EAG-13-516||6.4 g/t gold over 3.2 m from 340.3 m|
Drilling at Depth
Eagle Hill drilled three holes for 1,459 metres below Red Dog to test the extension of Zone 27 gold mineralization identified with EAG-12-320 (5.5 g/t gold over 15.0 m, see Eagle Hill press release dated March 1, 2012). Two wedges were set in EAG-12-320 and EAG-11-294 was extended. Drilling confirmed continuity of the mineralization over a distance of more than 40 metres. Results include:
|Section 2500||EAG-13-320-W1||37.3 g/t gold over 11.2 m from 752.5 m|
|inc.||166.5 g/t gold over 0.6 m from 755.5 m|
|and||289.0 g/t gold over 0.8 m from 785.2 m|
|Section 2500||EAG-13-294-EXT||12.3 g/t gold over 3.2 m from 710.1 m|
This drilling program and the on-going geological modelling has confirmed that the bulk of the gold mineralization is hosted in Zone 27, a sub-vertical lens extending from surface to a depth of 500 metres. This main gold-bearing lens is intimately associated with a sub-vertical porphyry dyke. Gold mineralization intersected below Red Dog is also associated with a porphyry dyke that extends further at depth.
Eagle Hill believes that the gold mineralization extends further at depth, as highlighted by the results of a recently completed hole-to-hole IP survey, and plans to follow up with additional drilling in 2014.
Hole-to-hole IP Survey at Depth Below Red Dog
Eagle Hill’s contractors completed an innovative hole-to-hole IP survey in 24 pairs of holes (Figure 3) with the objective of refining drill targets below Red Dog with similar signatures to the known resource mineralization above Red Dog. Three-dimensional inversion of these data has identified three major anomalies below Red Dog that are located on strike and down-dip from known gold-bearing lenses above Red Dog.
Based on these results, Eagle Hill will plan diamond drilling to test those newly identified targets with the objective of expanding the mineral resource below the Red Dog intrusive.
Surface IP Survey in Southern Part of Windfall Lake Property
Eagle Hill also completed a 70 line-km surface IP survey in the southern part of the property. This sector was selected because it contains NE-trending magnetic lineaments and magnetic low anomalies similar to that hosting the Main Zone. Results of the survey are being processed and will be available shortly.
Mineral Resource Update
Eagle Hill will release an updated mineral resource estimate in Q1-2014. The Company has more than 57,000 metres of new drilling to incorporate into the updated resource estimate, with 28,107 metres from the current drill program, and 106 holes totalling 29,208 metres that were drilled after the 2012 resource estimate and prior to the current program. All drill results have been released and are available on SEDAR at www.sedar.com and on the Company’s website.
“The Fall 2013 drill program successfully achieved our objective of proving that mineralized zones continue beyond the current limits of the known Windfall Lake resource to the southwest and below the Red Dog sill. That we encountered some very high-grade intervals underscores the potential of this high-grade gold deposit,” said Dr. Mike Andrews, Director and Interim President of Eagle Hill. “We are particularly encouraged by the confirmation of high-grade intervals below the Red Dog intrusion, leaving the deposit open for expansion at depth.”
2014 Drill Program
Eagle Hill has commenced a 2,200-metre drill program to test for extensions of Zone 27 under shallow lakes (2 to 6 metres depth) that are currently frozen. Eagle Hill plans to drill 14 holes to a depth of 120 to 250 metres to test the lateral extensions of Zone 27, where drilling has confirmed near-surface high-grade intervals such as 14.8 g/t over 16.0 metres (EAG-12-418).
Additional drilling for 2014 will be planned once the Company has reviewed the results of the mineral resource update, which will include SRK’s recommendations for advancing the property.
