NORTHMIN REPORTS HIGHEST GRADE COPPER AND SILVER RESULTS RECEIVED TO DATE FROM ITS TYNAGH DRILL PROGRAM

Northmin Corp. has released assay results from the second two drill holes drilled on the Tynagh mine site as part of its hard-rock silver-copper-zinc-lead exploration program at the 100-per-cent-owned Tynagh project in Republic of Ireland.

Highlights:

• Highest silver and copper assays received by Northmin to date:
  • 2.45 metres grading 4.03 per cent Cu, 24.87 per cent Zn plus Pb, 0.47 per cent Sb (antimony) and 313.82 grams per tonne Ag from 106.75 m in hole 3615-26-08;
  • Including 0.75 m grading 933 g/t Ag and 12.75 per cent Cu;
• Two holes, 3615-26-08 and 3615-26-09, intersected numerous mineralized intercepts, including broad zones of polymetallic mineralization, some of which contain high-grade intervals of copper, zinc, lead and silver (mentioned above);
• 3615-26-08, targeting polymetallic and copper-silver-antimony mineralization 50 m east of the high-grade copper intersection in hole 3615-26-07, intersected a broad zone of Waulsortian reef-hosted polymetallic mineralization with significant copper in the upper reef in addition to a lower reef-hosted high-grade copper-zinc-lead-silver intercept and footwall copper-silver-antimony mineralization;

• 3615-26-09, located 43 m east of hole 3615-26-06 and 33 m west of 3615-26-07, also intersected both Waulsortian-reef-hosted and Lower-Muddy-limestone-hosted zinc-lead-silver mineralization in addition to a zone of footwall copper-silver-antimony mineralization in the Lower Muddy limestone close to the Tynagh fault;

• In the Waulsortian reef limestone:

"Following on from the results of the first two drill holes in July, today's results are further validation of the potential to define broad zones of near-mine reef-hosted polymetallic mineralization and structurally controlled copper, antimony and silver mineralization along the Tynagh fault beneath the historically mined zinc-lead-silver mineralization. These results also show that the Lower Muddy limestone beneath the reef limestone is also capable of hosting broad zones of zinc-lead-silver mineralization and there is emerging evidence of fault splays within the reef that may explain copper-silver-antimony mineralization away from the main Tynagh fault. While the first four holes have now tested a strike length of 125 m, the observations from another four widely spaced holes that have been completed (assays pending) give us confidence that the project will continue to deliver positive drilling results from across the 1.6-kilometre strike of the historically mined deposit."

Tynagh drilling results -- further information

The two angled drill holes, 3615-26-08 and 3615-26-09, are the third and fourth holes drilled by the company in Zone 2 (open-pit area) to target both the polymetallic in situ reef-hosted mineralization and the copper mineralization hosted in the reef and in the Lower Muddy limestone adjacent to the Tynagh fault. Both holes have intersected encouraging mineralization, including broad intersections of polymetallic mineralization and high-grade copper-lead-zinc-silver mineralization in the Waulsortian reef. Both holes also intersected further copper-silver-antimony mineralization adjacent to the main Tynagh fault in the Lower Muddy limestone. Significantly, hole 3615-26-09 also intersected zinc and lead mineralization in the Lower Muddy limestone, with 19.7 m grading 0.11 per cent Cu, 2.4 per cent Zn plus Pb and 13.21 g/t Ag from 134.3 m, demonstrating that all lithologies near the fault can host polymetallic mineralization. No mine workings were intersected in the two holes reported here and there is no evidence of previous stoping in the drilling area.

The first four holes, drilled as part of the current 10-hole drill program, cover a strike length of 125 m and demonstrate reasonable continuity of the polymetallic mineralization within the reef. To date, high-grade copper-silver-antimony mineralization has been intersected along the Tynagh fault in the Lower Muddy limestone but also in the lower micrite reef in hole 3615-26-08, where the highest silver assay to date was returned: 0.75 m grading 12.85 per cent Cu and 933 g/t Ag within an intersection of 2.45 m grading 4.03 per cent Cu, 24.87 per cent Zn plus Pb, 0.47 per cent Sb and 313.82 g/t Ag from 106.75 m. The distribution of copper-silver-antimony mineralization, typical of feeder zones within Irish-type zinc-lead systems, along with drill core observations, suggests that this mineralization may be associated with splays oblique to the main Tynagh fault. Further drilling in combination with digitization and modelling of historic drill hole and mine data will shed more light on the structural model.

Barite mineralization was observed in core, mainly in the Waulsortian reef limestone. Pulps of mineralized samples within and surrounding the reported significant intersections will be reanalyzed for barium by method Ba-XRF05SQ, a semi-quantitative, cost-effective method.

The new results reported here are highly encouraging and consistent with the company's view that significant zones of shallow bulk polymetallic mineralization remain in situ in the micrite reef banks peripheral to the high-grade historic workings while there is strong potential for the discovery of further copper-silver-antimony zones in reef and subreef lithologies along the Tynagh fault. The company looks forward to providing further updates as more assays are received.

Sampling and analytical procedures

All core drilled at Tynagh and reported in this announcement was NQ (47.6 millimetres) and was cut in half using a rock saw. Sample intervals vary between 0.5 m and 2.92 m, with an average (over 160 samples) of 1.18 m. The half-core samples are bagged, labelled and sealed at the company's core shed facility on the Tynagh mine site, 15 kilometres from Loughrea in County Galway, Ireland. The core sampling was carried out by the qualified person. Transport of samples in sealed nylon sacks was by the qualified person to ALS Laboratories in the nearby town of Loughrea. ALS Minerals is a large, independent and ISO-certified analytical service company, originally based in Loughrea to serve the Tynagh mine. Sample preparation at the ALS facility was by method Prep-31, comprising fine crushing 70 per cent less than two mm, riffle splitting, pulverizing up to 250 g 85 per cent less than 75 micrometres. Analytical procedures are 48-element four-acid ICP-MS (codes ME-MS61). Overlimit analyses for Ag, Cu, Zn, Pb, Sb and As were by method ME-OG62. One sample exceeding 20 per cent lead (Pb) and 30 per cent zinc (Zn) was analyzed by XRF (X-ray fluorescence) by method ME-XRF15c. Barium values are not reported above as barite requires an alternative analysis method. The company will conduct further barite analyses on pulps from samples in the mineralized intervals.

Quality assurance/quality control (QA/QC) information

Northmin inserts certified reference materials (CRMs) as well as blank material and quarter-core duplicates to its sample stream as part of its industry-standard QA/QC program. The QC results have been reviewed by the qualified person, who is satisfied that all the results are within acceptable parameters. The qualified person has validated the sampling and chain-of-custody protocols used by Northmin.

The tailings ponds are accessible and there has been little to no rehabilitation of the site since mine closure in 1985. The company is also assessing the overburden and low-grade ore stockpile on the site and has previously announced high-grade silver results from first-pass sampling. The company also recently announced high-grade copper drill results from below the historic zinc-lead-silver mine at Tynagh, including 6.4 m grading 4.92 per cent Cu, 0.98 per cent Sb and 62.04 g/t Ag from 149.0 m in hole 3615-26-07.
