Toronto, Ontario, May 26, 2009. Noront Resources Ltd. (“Noront” or the “Company”) (TSX Venture: NOT) is pleased to announce assay results from twelve diamond drill-holes completed during in the latter part of the winter on the Blackbird chromite deposits, and provides an update on project progress.
- Hole NOT-09-1G130 intersects 21.5 metres averaging 41.58% Cr2O3, with Cr:Fe ratio of 2.13 within 30 metres of surface;
- Hole NOT-09-1G104 intersects 25.1 metres averaging 36.82% Cr2O3, Cr:Fe ratio of 2.02 including massive chromite intersection 5.2 metres wide averaging 40.61% Cr2O3 with Cr:Fe ratio of 2.11;
- Chrome resource delineation drilling nears completion, one drill re-assigned to test for nickel potential in vicinity of Eagle One;
- Drilling continues on chrome, while testing for additional base metal and PGE potential.
Noront’s late winter exploration program continued through the spring breakup of late April and into May. As announced on April 28, 2009, the Company has employed two diamond drills on the Blackbird deposits since the beginning of January and had completed a total of 17,680.9 metres of drilling in 63 holes. Since this time, an additional 25 holes have been completed totaling an additional 5,570 metres, bringing the total drilling for 2009 on the chromite project to 87 holes and 18,354 metres. As stated earlier this year, the primary goal of this drilling campaign is to define a National Instrument 43 – 101 compliant resource for the Blackbird discoveries by completing sufficient drilling at an optimum drill hole spacing to provide both inferred and indicated resources depending on the density of sampling and the domain type (massive vs. disseminated chromite). Noront has nearly completed its planned drilling on the chromite project, well ahead of schedule and budget and expects to deliver its National Instrument 43-101 compliant report by the end of 2009. The company has recently reassigned one drill to test for downward continuations or extensions of the Eagle One Deposit.
Since the last report of assays (April 28, 2009), Noront has received final assay data for twelve more of its chromite related holes. Assays for chromitite intersections in many other holes are pending, final results of which will be released as they become available. The following table provides assay highlights for the massive chromite intersections only for those holes where assays have been received since the last press release, and the chrome to iron ratio (Cr:Fe) is in excess of two to one (2:1) :
|Hole Number||from (m)||to (m)||int (m)||Cr203%||Cr%||Fe%||Cr:Fe|
|Notes: Drill intercepts are not true width intercepts; all measurements are in metres.|
The intervals sampled and reported by Noront include both massive chromitite and zones of intercalated beds of chromitite and heavily disseminated chromite hosted by talc-altered dunite and peridotite. For a complete set of assayed intervals for all twelve holes (NOT-08-1G101, 102, 104, 109, 110, 112, 114, 117, 118, 119, 130 and 131) please proceed to Noront’s website by following the link. https://norontresources.com/find/id/10/jx Of special note, there are a number of intriguing (anomalous to perhaps economic grade) base metal and precious metal drill intersections listed in the table. Hole NOT-09-1G117 intersected 9 metres averaging 0.92% Ni, 0.67 g/t TPM, Hole NOT-09-1G119 intersected 1.8 metres averaging 1.33% Ni, 0.56 g/t TPM, and Hole NOT-09-1G130 intersected 1.3 metres averaging 1.27% Ni, 3.27 g/t TPM. These type of intersections have become commonplace within and around the chromite deposits, and will be receiving some additional drill attention to determine their significance in the economic evaluation of the Blackbird deposits.

Quality Assurance and Quality Control:
All holes drilled are systematically logged and then sampled. Samples are shipped regularly to Actlabs in Thunder Bay, Ontario for sample preparation and initial analysis (TD-ICP) following strict chain of custody procedures. Final chromite and iron analyses were done by instrumental neutron activation (INAA) at the Actlabs facility in Ancaster, Ontario. Neutron activation is a method in which samples are irradiated by neutrons, causing the analyte elements to become radioactive. Counting the radioactivity of each activated isotope in comparison to the activity of a reference material such as Cr wire allows the determination of element concentrations with no matrix effect. For more information on Actlabs analytical procedures please visit Actlabs website at: http://www.actlabs.com Under Noront’s QA/QC program each batch of 35 samples includes one blank, two internationally certified reference materials (ICRM; henceforth referred to as standards), one quarter-sawn field duplicate, a coarse reject duplicate, and a pulp duplicate. These procedures are conducted in addition to Actlabs’ standard practise of further inserting one Cr standard within each reactor bundle of 11 samples. The pass/fail criteria for the new Cr standard and for the standards inserted by Actlabs are the same as for the Cu, Ni, Au, Pd and Pt standards previously reported. In particular, if measured concentrations in standards differ from accepted values by more than two standard deviations of the method as determined by numerous INAA repeats on the standards at Actlabs, the entire batch fails and is re-analysed. The standard deviation for 30 repeat measurements of the ICRM SARM 9 by INAA at Actlabs was 1.2% Cr2O3, giving a coefficient of variation of 2.6% and therefore a nominal precision of 5.2% (taken as twice the standard deviation). Precision of pulp splits within reactor batches as determined by the Thompson-Howarth method is 1.7%; between reactor batches it is 5%, matching very closely the apparent precision of 5.2% from replicate analyses of standards. Duplicates and standards are also monitored over periods of months to detect and correct, if necessary, any drift bias or changes in precision that might appear through time. All QA/QC procedures and checks are carried out by Tracy Armstrong, PGeo, of P&E Mining Consultants Inc, who acts as the Qualified Person for Noront on matters pertaining to assays. Currently reported data were all obtained by INAA.
Additional quality control measures have been recently adopted for Cr and Fe including the blind insertion of a certified reference material SARM 8, purchased from Mintek in South Africa, and a change from INAA to fusion X-ray fluorescence (XRF) to analyse chromite samples. For fusion XRF assays the samples are melted with borate fluxes and quenched to a glass bead, which is then irradiated with X-rays. The secondary X-ray emissions are counted and used, with reference to several calibrants, to determine the whole rock composition including the analytes and all other major oxide components of the rock. The additional compositional data would be of interest to buyers of any potential ore from the Blackbird deposits. The results of these new assays are still pending.
This press release has been reviewed and approved for dissemination by Noront’s senior management including Chief Geologist Jim Mungall Ph.D., P.Geo., Exploration Manager Jim Atkinson M.Sc., P.Geo., and Chief Operating Officer John Harvey P.Eng. all being Qualified Persons under Canadian Securities guidelines.
