On track to complete resource estimates and
resource conversions by March 31, 2013
Anglesey Mining plc (“Anglesey”) is pleased to report that its 19.7% owned associate Labrador Iron Mines Holdings Limited (“LIM”) has announced the completion of its 2012 exploration field program totalling 14,000 metres (“m”) of diamond and reverse circulation (“RC”) drilling. This represents the largest exploration program ever completed by LIM. LIM’s field crew is now working on several of its Schefferville area iron ore projects in both Newfoundland and Labrador and Québec towards the completion of geological core logging and sampling in early 2013 and anticipates several new and updated National Instrument 43-101 (“NI 43-101”) compliant resource estimates on its deposits for completion by the end of its fiscal year.
Exploration Program Highlights
- During the 2012 field season, LIM completed 14,000 m of diamond and RC drilling, a 40% increase over the planned 10,000 m.
- LIM is on track to complete by March 31, 2013, updated resource estimates for two major deposits: i) the James Deposit (currently in production), including the James South Extension and, ii) the Houston deposits (currently 22.9 million tonnes of Measured and Indicated mineral resources – see press release dated May 31, 2012).
- LIM is also on track to complete new and initial mineral resource estimates on the Malcolm deposit (nearby Houston), the historic crushed ore stockpiles in both Québec and Labrador and its first inferred mineral resource estimate on the Elizabeth Lake Taconite.
- Drill results at Malcolm-1 returned ore-type intersections (grading >50% Iron (“Fe”)) in 11 of the 14 holes. Highlights include hole RC-M026, which intersected 21 m at 60.8% Fe and hole RC-M018, which intersected 18 m at 58.8% Fe.
- During the 2012 exploration program, LIM also acquired geological information through the use of diamond drilling, which successfully recovered core samples for the first time. These samples will now provide better bulk density, geotechnical, metallurgical and hydrogeological interpretations required for detailed mine planning.
“In our 2012 drilling season, our exploration team demonstrated their experience and competence by successfully delivering the most ambitious program in LIM’s history” commented Rod Cooper, LIM’s President and COO. “As a result, we are on track to complete several new and updated resource estimates by the end of our fiscal year. Equally as important, the field information collected this year will not only contribute to the development and delineation of our resource base, but will also provide valuable technical information for strategic mine planning. Preparation work has now commenced for another ambitious exploration program in fiscal 2014, scheduled to commence in April 2013.”
2012 Exploration Work Program Details
LIM used two exploration drill contractors during the 2012 field season: Cabo Drilling Corp. carried out the RC drilling and Major Drilling Group International Inc. carried out the diamond drill work. In previous seasons, LIM used RC drilling exclusively. The 2012 exploration program was successful in generating core samples through the use of traditional diamond drilling, a significant technical achievement. LIM obtained a high level (85%+) of core recovery with the use of highly-skilled personnel and special drilling additives and more than 8,300 m of HQ3 core (61.1 mm diameter) were recovered by the end of the program in mid-November. Logging and core splitting is ongoing on site and the exploration team is expected to complete its sampling in early 2013 to allow the inclusion of all new data and assay results in the next series of mineral resource estimates.
LIM is anticipating new mineral resource estimations on the James Deposit (including the James South Extension), Malcolm-1, Houston 1, 2 and 3 and on the historic crushed ore stockpiles. An initial mineral resource estimation will also be provided on the Elizabeth Lake Taconite.
The 2012 exploration program also successfully tested a system for geophysical down-hole bulk density determinations in the James and Houston orebodies, which promises to yield a valuable contribution to the resource estimation efforts in the future.
Malcolm-1 Drill Results
The Malcolm-1 area lies approximately 3 kilometres northwest from the Houston orebodies. Initial work on this property was carried out by LIM in 2011 and returned ore-type intersections in 14 of 18 holes drilled (see to press release dated May 31, 2012). In 2012, RC drilling on the Malcolm-1 property consisted of 14 holes totalling 1,600 m and 11 of the 14 holes returned ore-type intersections. Figure 1 outlines the hole locations from the 2011 and 2012 drill programs, as well as the historical resource previously identified by the Iron Ore Company of Canada (“IOC”). The historical (non NI 43-101 compliant) mineral resource is 2.9 million tonnes grading 56.2@ Fe. A manganese resource was also identified by IOC, totalling 422,000 tonnes at a grade of 51.4% Fe. LIM expects to report a new NI 43-101 compliant mineral resource for the Malcolm-1 deposit by the end of its fiscal year.
Table 1 below summarizes the intercepts from the 2012 drill program. True thickness (ETT) is estimated using an average bedding dip of 45 degrees and vertical drilling dips for every RC hole.

Other Exploration Work Program Details
LIM was also able to increase the capacity of the mine site sample preparation facilities to allow a better turnaround time in the receipt of assays from off-site laboratories. Actlabs remained as independent managers of the site preparation laboratory and all reduced and pulverized exploration samples were airfreighted to its analytical laboratory in Ancaster, Ontario for multi-element X-ray fluorescent (XRF) assays including Actlabs internal Quality Assurance / Quality Control (QA/QC) procedures.
Ground Geophysical Surveys: Geosig Inc., a Quebec-based geophysical consulting firm carried out a series of ground magnetometer and gravity surveys over several main targets including the Gagnon and Elizabeth taconites and over the James, the Houston, the Malcolm-1 and the Howse direct shipping (DSO) iron ore deposits. The gravity survey covered 48 line-kilometres (line-km) and 1,130 gravity stations were collected. The magnetic survey covered 31.4 line-km and 40,326 measurements were recovered. These surveys have confirmed the validity of airborne gravity anomalies, located the extensions of known ore bodies and suggested the presence of new exploration targets.
