Advanced Explorations Extends High Grade Fe Mineralization and Identifies New Exploration Opportunities
TORONTO, ONTARIO--(Marketwire - Feb. 13, 2008) - Advanced Explorations Inc. (the "Company or AEI") (TSX VENTURE: AXI.V) is pleased to announce results from drilling on Zone C1 on its Roche Bay, Nunavut iron project, and the identification of new exploration targets. Drilling results have extended the strike of the previously reported higher grade (greater than 30% Fe) mineralization of Zone C1 and identified several additional sequences of adjacent lower grade (24% to 26% Fe - see Table 1) banded iron formations (BIF) that are believed to also have economic potential. In addition, the first indication to the potential for zones of secondary iron enrichment was recognized in the most southwesterly exploration drill hole (RB-07-06). Two narrow, closely spaced, very high grade enriched iron zones (see Table 2 below) averaging 63.5% Fe and 53.8% Fe intersected at a vertical depth from surface of over 110 metres indicates the possibility of discovering near surface enriched high grade iron mineralization.
Drilling on the northern extent of C1 has identified a vertical to steeply east dipping zone of high grade banded iron formation that averages 200 metres in thickness, which is characterized by significant sections that grade in excess of 30% Fe in which iron mineralization occurs almost exclusively as magnetite. Only about 2km of the over 5 km of strike has been drilled in detail. This zone remains open to the north and to the south where it appears to be offset by a fault to the east. Drilling has locally tested C1 mineralization in excess of 300 metres vertical depth from surface (analytical results outstanding). Holes RB-07-27 and RB-07-28 drilled on line 1800S are indicative of the higher grade section of C1. Hole RB-07-27 intersected 106 metres averaging 30.41% Fe and Hole RB-07-28 drilled from the same collar location but opposite direction intersected 128 metres averaging 32.32% Fe. (Hole lost at 229 metres ended in BIF grading 33.85% Fe)
A resource calculation and economic study are underway and the Company is currently planning the 2008 drill program which will focus on both in-fill drilling and extending the strike of the high grade zone of C1. Drilling will also commence on the eastern flank of the C Zone (C2) and on the A and B Zones which were the focus of drilling and economic studies in the mid 1980s. At that time the A-B Zones reported a historic resource of 467 million tons ranging from 24% to 34% Fe. The Company has not verified the classification of the historic resource reference and is not treating it as a NI 43-101 defined resource verified by a QP. Although this historical reference of resource potential is relevant to recognizing the potential of the Roche Bay Property, it should not be relied upon. The Company plans to start with 2 drills and expand to 4/5 drills as weather improves.
John Gingerich, President and CEO of AEI, commented;
"We are very encouraged by the results which extend the strike of high grade banded iron formation (C1) with widths at surface up to 270 meters. What has pleasantly surprised us is the presence of parallel iron formations in the footwall that also appear to have economic potential. On the C Zone we have only begun drilling the west flank (C1) and the east flank (C2) as well as the targets on all other leases remains untested. Roche Bay is a very exciting project which continues to reveal additional potential."
Project Summary:
A complete project review is underway in support of the resource calculation, economic studies and the launch of the 2008 drill program. One outcome of the review is that the geologic section represents a simple east facing inclined (not a synform) sedimentary sequence which contain several units of banded iron formation that in general terms appear to increase in grade to the east. The C Zone comprises two major magnetic trends, C1 and C2. Last year's exploration drilling focused on assessing the strike extent of C1 with detailed drilling focused on the higher grade and magnetite rich banded iron formation. Exploration drilling was also carried out to assess banded iron formations within the footwall sequence. Initial drilling was carried out using single setups and multiple directions to better define mineralization geometry. Holes in many instances drill iron formation in both directions.
The geologic interpretation of C1 is that it consists of three distinct styles of mineralization. The high grade magnetite mineralization is characterized by massive banded iron formation having a width at surface ranging from 170 metres to 270 metres. The eastern contact and location of this high grade BIF is defined by a late gabbro intrusive that strikes subparallel to the formation. The high grade BIF can be locally displaced to the east and/or digested within the intrusive. In addition there appears to be a left-handed fault (orientation and offset not precisely defined) that appears to dislocate the higher grade BIF sequence in the vicinity of 2600S. There is a transition zone along the western flank of the high grade BIF that ranges from 50 metres to 100 metres on surface with grades ranging from 26% to 29% Fe. The gradational decrease in grade is also characterized by a slight corresponding decrease in magnetite content. The western contact of the transition zone is defined by a 20-40 metre thick sedimentary unit with low iron content. The remaining sequence (lower footwall) is characterized by multiple, generally narrow sequences of banded iron formation within a broad sequence of calc silicates. The BIF sequences range from 20 to 120 metres in thickness with grades ranging from 24% to 28% Fe. The BIF sequences are not only of lower grade but in general the percentage of total Fe that is magnetite decreases (early analysis suggests 65% to 80% of total iron is magnetite and metallurgical review is underway). The western limits of the sedimentary sequences terminate at a faulted contact with a volcanic unit.
The stratigraphic sequence that defines the eastern magnetic anomaly (C2) is not well defined at this time. Mapping has locally defined well mineralized outcrops of BIF but strike and thickness have yet to be verified with drilling. There is more gabbroic intrusive to the east which typically form local ridges with adjacent areas of shallow talus/overburden covering most of the targets and the reason for limited work to date. With a noted gradational improvement if BIF grades to the east in C1 and local outcrop mapping of massive BIF, drill testing of C2 early in this year's campaign is a priority.
The Company is still awaiting complete results and/or QA/QC review (partial to all) on 12 drill holes 10 of which are on the northern main zone of C1. The delays in receiving analyses from the lab are impacting the timelines for the independent resource calculation to be completed. However these delays have not affected the timeframe for the economic studies which are currently moving forward. Work is being done in parallel in the preparation of an economic study so any delays in getting the information required for the resource calculation will not affect the Company's initial objective to complete the preliminary economic study by this summer.
In preparation for the resource determination the Company undertook a technical audit review of its geotechnical results and QA/QC procedures. The review has not identified any errors in its analytical process but did identify a need to improve database management and information flow.
As a result additional QA/QC management procedures and reporting structure are being implemented. Improving the flow of information and laboratory analysis is a Company priority to avoid the delays experienced in last year's program. Further to this review, all mineralized intervals have been updated using an 18% Fe cutoff and internal dilution zones in excess of 9 meters identified. The significant and updated intervals are summarized in Tables 1 and 2.

Analysis: All the recent drill core analysis reported in this release was performed by SGS Lakefield Research. At SGS samples are analyzed for total Fe using XRF techniques. SGS also undertakes Satmagan analysis to estimate the portion of magnetic iron. The company augments the laboratory QA/QC procedures by selectively adding additional control samples. Core sample intervals are 1 metre except where intervals cross geologic boundaries in which case the sample length is adjusted accordingly.
