Eagle Plains/Providence Identify 3 High-Priority Drill Targets from 2011 Airborne EM Geophysical Surveys
Vancouver, B.C., February 21, 2012: Eagle Plains Resources Ltd. (TSX-V:EPL) and Providence Resources Corp. (TSX-V: PV) are pleased to announce receipt of results from airborne geophysical field surveys carried out over their Iron Range JV project located near Creston British Columbia. During October-November 2011, Geotech Ltd. carried out VTEM time-domain EM and ZTEM AFMAG surveys over parts of the Iron Range Project. The results have subsequently been processed and interpreted by Condor Consulting, Inc. of Lakewood Colorado.
- 440 line-km of airborne geophysical data has been collected over the Property area during 2011.
- 3 high-priority VTEM electromagnetic geophysical anomalies have been delineated in the Row target area, and are coincident with a 5km-long arsenic, zinc and lead soil geochemical anomaly.
- The ZTEM survey successfully identified the Iron Range Fault as well as a northeast-trending fault similar in orientation to the gold-bearing faults at the Talon Zone.
“Geophysical data collected on the Iron Range Project has produced three high priority EM conductors that coincide with lead, zinc and arsenic geochemical anomalies on the Row Target Area.” Stated Providence Resources Corp.’s President and CEO Vince Sorace. “The combined results from the geophysical surveys have fine-tuned the Iron Range geological model and increased our confidence in the Row Target area which will be drill-tested upon receipt of applicable permits, which are expected by Q2, 2012.”
Geophysical Survey Results
VTEM time domain-EM
A total of 7 anomalies were defined from the VTEM survey; see vtem_2011geophysicsmap.pdf. Anomalies 1-3 represent high-priority EM anomalies and are located within and immediately adjacent to a ~5 kilometer-long lead-zinc-arsenic soil anomaly situated in prospective middle Aldridge Formation sedimentary rocks. These three anomalies may be an indication of subsurface Sullivan style lead-zinc-silver mineralization and will be drill tested in Spring, 2012. Anomalies 4 to 7 represent secondary priority targets and are likely related to the subsurface geology. Anomaly 4 is a broad, low level conductor associated with a magnetic contact and is interpreted to represent a near-surface bedrock anomaly or conductive overburden. Anomaly 5 is a formational anomaly defined by coincident EM and magnetic anomalies which correspond to the location of a sliver of upper Aldridge Formation sedimentary rocks. Anomaly 6 is a broad, northeast trending conductive zone associated with a linear, northeast trending magnetic anomaly. Drilling done in this area indicates that the anomaly is related to graphite within the Aldridge Formation sedimentary rocks. Anomaly 7 is interpreted to be an artifact that is related to a power line that transects this portion of the VTEM survey.
ZTEM AFMAG Survey
The ZTEM orientation survey was conducted over the Canyon Target (Talon Zone) to determine whether this geophysical method would be capable of mapping bedrock geology based upon the known resistivity and magnetic susceptibility contrasts within the Aldridge sedimentary rocks; see ztem_2011geophysicsmap.pdf. The survey successfully identified the Iron Range Fault as well as a northeast-trending fault similar in orientation to the gold-bearing faults at the Talon Zone. In addition, the survey identified the broad conductive zone also detected by the VTEM survey. This information is useful in better understanding the subsurface geology of the Iron Range area and how known target areas relate to major rock units and structures.
2012 Exploration Program
The Company intends to execute a full exploration program beginning in March, 2012 (subject to receipt of permits) with the objective of systematically evaluating all existing exploration data, utilizing newly acquired geophysical data, field evaluating all resulting anomalies and ultimately drill testing the highest priority targets.
- Geophysical gravity survey – it is anticipated that results from this work will be available in March, 2012.
- Winter drilling (Phase I) of high-priority geophysical and geochemical anomalies. High priority targets have been identified during the evaluation of historical geochemistry, 2011 soil geochemical surveys, and 2011 airborne geophysical data. Additional targets are anticipated.
- Field work will be completed in summer 2012 with the objective of bringing remaining targets to the drill testing stage for Phase II drilling in late 2012.

Iron Range Project Summary
The Iron Range deposits were originally staked in 1897, and were covered by Crown grants held by Cominco Ltd. and the Canadian Pacific Railway. Eagle Plains Resources (“Eagle Plains”) staked the current claims immediately after the Crown grants reverted in 2000, and it has been exploring the property since then. Exploration work to date includes geological mapping, geochemical surveys, diamond drilling and a 690-line-kilometre airborne geophysical survey.
The Iron Range project is owned 100% by Eagle Plains and holds no underlying royalties or encumbrances. An additional 35,800 hectares of claims were added to the original land package, resulting in a total of 56,200 hectares -- an area approximately 11 km by 50 km. The land package now covers over 30 km of the Iron Range structure, most of it unexplored. The claims also overlie rocks of the Aldridge formation, including the same stratigraphic time horizon that hosts the world-class Sullivan deposit located 70 km to the northeast. Over its 100-year lifetime, Sullivan produced approximately 150 million tonnes of ore including three billion ounces of silver, eight million tonnes of zinc and eight million tonnes of lead, collectively worth over $30-billion at current metal prices. The parties caution that past results or discoveries on proximate land are not necessarily indicative of the results that may be achieved on the Iron Range property.
Providence Option Agreement
The Iron Range project is owned 100% by Eagle Plains and holds no underlying royalties or encumbrances. Providence holds the option to earn a 60% interest in the Property by spending $3,000,000 on exploration, making $500,000 in cash payments and issuing 1,000,000 shares to EPL over 4 years.
Geophysical Survey Specifications
Versatile Time Domain Electromagnetic Survey (VTEM)
The Geotech Ltd. airborne VTEM survey was flown in an east to west (N 172° E azimuth) direction, with a line spacing of 200 meters. Tie lines were flown perpendicular to the traverse lines (N 82° E azimuth) at a spacing of 1800 meters respectively for a total of 282.3 line kilometers. This survey also included a cesium magnetometer. The VTEM plus receiver and transmitter coils were in concentric-coplanar and Z-direction oriented configuration. The receiver system for the survey also included a coincident-coaxial X-direction coil to measure the in-line dB/dt and calculate B-Field responses. The EM bird was towed at a mean distance of 35 meters below the helicopter.
Z-Axis Tipper Electromagnetic Survey (ZTEM)
Geotech Ltd. carried out a 160.0 line-kilometer, helicopter-borne AFMAG Z-axis Tipper electromagnetic (ZTEM) and aero magnetic (caesium magnetometer) geophysical survey centered on the Canyon Target Area. The survey was flown in a southwest to northeast (N 78° E azimuth) direction, with flight line spacing between 200 and 250 metres (mean height of 277 meters). Tie lines were not flown. According to survey specifications, a vertical-dipole air-core receiver coil and two orthogonal, air-core horizontal axis coils are placed close to the survey site to measure the horizontal EM reference fields. Data from the three coils are used to obtain the Tzx and Tzy “Tipper” components at six frequencies in the 30 to 720 Hz band.
