Eagle Hill Exploration Corporation: Updated Mineral Resource Statement Results in 126% Increase in Inferred and 61% in Indicated Gold Ounces at Higher Grade at Windfall Lake Deposit

VANCOUVER, BRITISH COLUMBIA--(Marketwire - July 25, 2012) - Eagle Hill Exploration Corporation (TSX VENTURE:EAG)(OTCQX:EHECF)(FRANKFURT:EH0) ("Eagle Hill" or the "Company") is very pleased to announce the preparation of a second independent gold mineral resource statement for the Windfall Lake Property (the "Windfall Lake Property" or the "Property") in accordance with Canadian Securities Administrators National Instrument 43-101, by SRK Consulting (Canada) Inc. ("SRK"). The updated mineral resource statement represents a significant increase in the total amount of gold ounces and an important increase in grade due to additional drilling and improved domain modelling.


The results of the updated gold resource indicate:

  • A 61% increase in the total amount of gold ounces in the indicated category with a 10% increase in grade to 10.05 grams per ton of gold;
  • A 126% increase in the total amount of gold ounces in the inferred category with a 31% increase in grade to 8.76 grams per ton of gold;
  • 40% of the Gold Resource is in the Indicated category;
  • Mineral Resource reported at a cut-off grade of 3.0 gram of gold per tonne ("g/t of Gold"):
    • Indicated Resource of 1.665 million tonnes at 10.05 g/t of Gold (538,000 Gold ounces)
    • Inferred Resource of 2.906 million tonnes at 8.76 g/t of Gold (822,000 Gold ounces)
  • Over 80 percent of the mineral resource lies within an area of 450 metres by 850 metres and within the first 500 metres from surface;
  • To date, Eagle Hill's exploration costs have been approximately $10 per ounces of gold resource discovered; and
  • Mineralization remains open along strike and at depth.

The Revised Mineral Resource Statement* is presented below:

* Mineral resources are not mineral reserves and do not have demonstrated economic viability. All figures have been rounded to reflect the relative accuracy of the estimates. Reported at a cut-off grade of 3.0 g/t gold assuming an underground extraction scenario, a gold price of US$1,200 per ounce and metallurgical recoveries of ninety seven percent.


"We are pleased to be able to provide such a strong update to our initial mineral resource statement in such a short period of time. In only 8 months, we have significantly increased the number of ounces of gold and increased the grade in both the indicated and inferred categories. This confirms the immense value being realized by our systematic approach to exploration. Our efficient and cost effective drilling program has continued to deliver strong results and improved the continuity and confidence in the mineral resource," stated Dr. Jean-Philippe Desrochers, Chief Geologist of Eagle Hill. "Our updated Mineral Resource Statement reaffirms that the Windfall deposit has significant gold mineralization, with significant potential to grow in size with further systematic exploration."

2012 Exploration Program

In addition to the updated resource calculation, recent near surface drilling at Windfall Lake has identified gold mineralization that could potentially be extracted by open-pit. Several near-surface, wide intercepts of significant grade have led the company to augment the current program to examine this potential with additional drilling. Recent intercepts include:

  • EAG-12-394: 41.8m of 4.6 g/t Au (July 11, 2012)
  • EAG-12-393: 47.2m of 11.8 g/t Au (June 21, 2012)
  • EAG-12-351: 55m of 5.7 g/t Au (April 26, 2012)
  • EAG-12-318: 25m of 22.85 g/t Au (February 27, 2012)

In addition to the near surface gold mineralization present at Windfall, recent drilling has demonstrated that mineralized zones continue to a depth of 770 metres below the surface with intercepts such as 8.9 g/t gold over 14.0 metres and 5.5 g/t gold over 15.0 metres below the Red Dog intrusion (March 1, 2012 press release). This deeper gold mineralization has not been included in the mineral resource statement presented here because of the paucity of drilling in this sector. However, additional drilling below the Red Dog intrusion may continue to increase the size of the mineral resource.

The drill program initiated in late May 2012 is focusing on three main objectives:

  1. Detailed definition drilling of the near surface gold mineralization with an objective to support evaluation of mineral resource that could be mined by an open pit operation;
  2. Expansion of the known gold zones to the east through a systematic drill pattern - the expansion of this gold mineralization to a depth of up to 450 metres could be mined through the existing ramp infrastructure at the Windfall Lake Property; and
  3. Discovery of additional continuous gold mineralization below the Red Dog intrusion where significant gold mineralization has been discovered by our recent drilling. Eagle Hill believes that more gold mineralization can be found at greater depths since Archean gold deposits generally have a much greater vertical extent then their strike length. The gold mineralization at Windfall Lake has a current horizontal strike length of over 2,000 metres and is still open to both the East and West.

A map of the Windfall Lake property outlining the location of the gold zones, drill holes and areas of potential expansion, together with cross-sections, a longitudinal section and pictures of core showing the mineralization style have been posted on Eagle Hill's website, www.eaglehillexploration.com/sections.

The Windfall Lake Property is located in Quebec, ranked by the Fraser Institute as one of the most favourable jurisdictions in the world for new mine development. Also favourable to mine development, is the Property's significant infrastructure including: year round road access, a 58 person camp, a recently constructed 1,450 metre underground ramp that is 5 metres in diametre, two power lines traversing the Property, and close access to skilled contractors.

Technical Description

The new Mineral Resource Statement documents significant changes relative to the previous mineral resource statement released in November 2011. The increase in tonnage and grade is primarily due to increased drilling and improved domain modelling. SRK used the same reporting parameters for this updated Mineral Resource Statement as those used in the first Mineral Resource Statement (3.0 gpt gold, US$1,200 per ounce of gold, and a gold recovery of 97 percent). The reporting cut-off grade of 3.0 grams per tonne based on the assumption that that the Windfall Lake gold deposit is amenable for underground extraction.

The gold mineralization occurs within a low pressure zone along a high strain deformation corridor trending northeast and characterized by variable hydrothermal alteration with pyrite stockwork and disseminated pyrite mineralization. Based on current exploration knowledge, the deposit was sub-divided into three zones for resource modelling. The bulk of the gold mineralization occurs in the Main Zone that was sampled by drilling on sections spaced at twenty-five to fifty metres. With the additional core drilling information acquired in 2011 and 2012, two of the previously defined gold zones (Main the East Extension zones) were combined into an expanded Main Zone. Two smaller, less-well-defined zones exist to the north (F17 Zone) and northeast (F51 Zone) of the Main Zone and are characterized by well-developed shearing but located in a separate, sub-parallel deformation zone north of the Main Zone and dipping approximately 65 degrees to the northwest.

The Windfall Lake Property database contains 567 diamond drill holes, 318 of which are located within the resource estimation area. Analytical data for the Property is primarily sourced from drilling completed between 2004 and 2012 by Murgor Resources Inc., Noront Resources Inc. and Eagle Hill. The drillhole data includes collar location, down-hole survey data, lithology codes and 55,073 sample intervals assayed for gold. The mineral resource statement is informed by a total of 142,427 metres of diamond drilling.

The mineral resources reported herein have been estimated using a geostatistical block modelling approach informed from borehole data. All zones were estimated using a traditional wireframe interpretation constructed from a sectional interpretation of the drilling data. In areas with limited drilling, the sectional interpretation was guided by grade shells constructed using the Leapfrog software. The block model was set on a grid of 5 by 5 by 5 metres, rotated by 30 degrees counter clockwise such that the block model is oriented subparallel to the general strike of the mineralization. Gold grades were estimated by ordinary kriging and compared with an inverse distance algorithm (power of two) as a secondary estimator using the same estimation parameters.

The block model was created to cover the entire area of gold mineralization at the Windfall Lake Property. Two estimation runs were used to populate the block model with gold grades for zones constrained by hard mineralization wireframes. The first and second estimation passes considered full and twice variogram ranges.

SRK is satisfied that the geological modelling honours the current geological information and knowledge. The location of the samples and the assay data are sufficiently reliable to support resource evaluation and do not present a risk to resource classification. The mineral resource model is largely based on geological knowledge derived from boreholes drilled on sections spaced at 25 metres apart in the Main Zone portion of the deposit and over 50 metres in the rest of the deposit. The geological information is sufficiently dense to allow modelling with reasonable confidence the boundaries of the gold mineralization for the Main Zone (Domain 100), while for Zones F17 and F51 (Domains 200 and 300), the geological continuity can only be inferred at the current drill spacing within the meaning of the CIM Definition Standards for Mineral Resources and Mineral Reserves (November 2011).

Generally, for mineralization exhibiting good geological continuity investigated at an adequate spacing with reliable sampling information accurately located, SRK considers that blocks estimated during the first estimation run considering full variogram ranges can be classified in the Indicated category within the meaning of the CIM Definition Standards for Mineral Resources and Mineral Reserves (November 2011). For those blocks, SRK considers that the level of confidence is sufficient to allow appropriate application of technical and economic parameters to support mine planning and to allow evaluation of the economic viability of the deposit. Those blocks located in the Main Zone can be appropriately classified as Indicated. Conversely, blocks estimated during the second pass considering search neighbourhoods set at twice the variogram ranges and all those blocks located in domains where the geological continuity can only be inferred should be classified in the Inferred category because the confidence in the estimates is insufficient to allow for the meaningful application of technical and economic parameters or to enable an evaluation of economic viability.

The mineral resource estimation work was completed by Dr. Lars Weiershäuser, P.Geo. (APGO #1504), and Dorota El-Rassi, P. Eng. (APEO #100012348) under the supervision of Dominic Chartier, P.Geo.
