TORONTO, Dec. 17, 2012 /CNW/ - New Dawn Mining Corp. (TSX: ND) ("New Dawn" or the "Company") announced updated Mineral Reserve and Mineral Resource ("MRMR") estimates for each of its six gold mining properties in Zimbabwe. Five of the properties, specifically, the Turk and Angelus, Dalny, Golden Quarry, Camperdown and Old Nic Mines, are currently in operation producing gold, while the sixth gold mining property, the Venice Mine, is currently on care and maintenance. The updated MRMR estimates were prepared by Michael Othitis, an independent qualified person, and will be set out in technical reports prepared in compliance with National Instrument 43-101 ("NI 43-101").
As a result of the updated Mineral Reserve and Mineral Resource estimates, which are reported on a total basis without adjustment for any minority interests, New Dawn now wholly-owns or controls a total of 2,290,500 ounces of gold grading 2.14 grams per ton ("g/t") from 33,357,400 tons of mineralized material in the Measured and Indicated Mineral Resource categories. Included within the Mineral Resources are Proven and Probable Mineral Reserves totaling 494,400 ounces of gold grading 1.52 g/t from 10,145,700 tons of mineralized material. In addition, there are 607,500 ounces of gold grading 4.29 g/t from 4,401,000 tons of mineralized material contained in the Inferred category.
The new Mineral Resource estimate represents a 44.1% increase in the Measured and Indicated categories (both of which include Mineral Reserves) and a 123% increase in the Proven and Probable Mineral Reserve category, as compared to the Company's previously announced MRMR estimates.
"Over the last 2 years, by systematically reviewing, upgrading and updating our geology and mining databases, and by conducting low cost but effective exploration programs, New Dawn has been able to add significantly to its gold resource base at a low cost relative to industry peers," commented Ian R. Saunders, New Dawn's President and CEO. "As production levels trend upward, these additional gold ounces will prove to be a valuable asset as New Dawn continues its focus on increasing sustainable gold production over the long term."

The Mineral Reserves for each property are included in the Mineral
Resource estimate for that property.
The MRMR estimates in the tables above are presented on a total basis without adjustment for minority
interests. New Dawn, through its subsidiaries, owns 100% of the Turk and Angelus, Old Nic and
Camperdown Mines, and approximately 85% of the Dalny, Golden Quarry and Venice Mines.
The Mineral Resources and Mineral Reserves have been estimated using specific and appropriate definition standards created for each property based on the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") Mineral Resource definitions referred to in NI 43-101 - Standards of Disclosure for Mineral Projects.
The Mineral Resource estimation methodology for each property is summarized in the following table:

|Venice||Manual||1.2||30||30||Survey / Plinning||Wt Avge||20||3.00||0.8||3 DIS||1/2 DIS / 2 Int||Att:I M-HGC|
|Manual Method uses plans/sections||X=block width||Plinning uses plans/sections||Qtz = Quartz Reef||M = Measured; I = Indicated; Inf = Inferred Resources|
|Computer Method uses Vulcan 3D||y = along strike distance||Triangulation volumes calculated||Sf = Sulphide-rich Ore Zone||DIS = Development intersection of 30m strike|
|Modelling Software||Z = block height||by Vulcan software||Int = Intersection of full reef width (drillhole, X-cut)|
|Wt Avge = weighted average||Att:I M-HGC = Attached to indicated Block with|
|medium to high geological confidence|
|SI = Sample Intersections (1m Bh or channel sample)|
For the Turk and Angelus, Dalny, Old Nic and Venice Mines, all of which are reef mines, all estimated calculations were performed manually, using longitudinal and cross sections, with block dimensions as stated in the table above. The X value in the above table is the average reef width of all blocks, but in the calculation, individual blocks were calculated using the average reef-width in that block. The Y value represents the length of the along-strike direction of the block, while the Z-value represents the height of the block, which is the height between mining levels (usually 30m). Volumes were calculated from plans and sections using a plinometer and based on survey data collected for each block in which the reef-width was measured. In all cases, a rock density of 2.67 tons per cubic metre (t/m3) was used in converting volumes to tons (based on historic data for the reefs). Grade estimates were calculated using weighted averages of all assay data within a block, with high assay values being cut down to a maximum value as noted in the table above. The classification of blocks into Resource categories (a) was determined on the basis of the average block grade being greater than the Mineral Resource cut-off (determined at 75% of the calculated pay-limit for each mine) and (b) was dependent on the number of informing intersections and geological confidence as per the table above for the different properties. Informing intersections consist of development intersections (channel sampling at 2m intervals along a drive, raise or cross-cut and cut as a channel across the full width of the exposed reef) or borehole intersections that have shown the full width of the reef (with widths corrected to true widths). Conversion from Mineral Resources to Mineral Reserves was based on (a) application of modifying factors to each block (incorporating items such as dilution and mining losses), (b) whether the average grade of a block was above the pay-limit for the mine after the application of modifying factors, and (c) whether the block was accessible for mining. Where these conditions were fulfilled, Measured Mineral Resource blocks were promoted to Proven Mineral Reserve blocks and Indicated Blocks were promoted to Probable Mineral Reserve blocks.
For the Golden Quarry (GQ) and Camperdown (CA) Mines, in which the ore-bodies are more massive in nature, Mineral Resource estimation was performed using Maptek's Vulcan 3D software. The dimensions of individual blocks within the Block Model (BM) are as per the above table. The dimensions of the entire BM for GQ were 190x410x300m and for CA were 1000x1000x400m, along the X, Y, Z axis of the model. For GQ, historic data from 239 surface diamond drill holes, 860 underground diamond boreholes, and 2,243 underground channel sampling traverses were used to produce 22,574 1m composite samples for use in the estimation process. For CA, historic data comprising 176 surface diamond boreholes, 869 surface percussion boreholes, 59 underground diamond boreholes, and 470 underground channel samples were used to produce 10,375 1m composite samples for use in the estimation process. Grade estimation was performed by Maptek Consulting, and the process was conducted using Ordinary Kriging methodology using the 1m composites created from the validated borehole and channel sampling databases. A bulk density of 2.67t/m3 was used for GQ, while a bulk density of 2.75t/m3 was used at CA, to calculate tonnages from the volumetric estimates of the Mineral Resources block model.
In the case of dumps which are included in the Measured Resource estimates, volumes were established using either traditional surveys or Maptek's iSite survey system, and grades were obtained via a comprehensive auger drilling program in which samples collected from each borehole were composited to provide a grade value. In addition, metallurgical testwork was also performed on the composite samples to determine potential grades and recoveries. A bulk density of 1.30t/m3 was used for all slimes dumps and a bulk density of 1.60t/m3 was used for rock dumps. Where a current survey for volume could not be conducted, the volume was measured from historic plans and an Indicated Mineral Resource category was assigned to the dump.
The updated mineral resource estimates were prepared in accordance with NI 43-101 guidelines using the CIM Mineral Resources and Reserves, Definitions and Guidelines prepared by the CIM Standing Committee on Reserve Definitions, and adopted by the CIM Council on December 11, 2005. The technical information in this news release has been prepared under the supervision of Michael M. Othitis, an independent qualified person for purposes of NI 43-101. Technical reports on each property, prepared by Mr. Othitis in compliance with 43-101, are expected to be filed by the Company on SEDAR on or about December 20, 2012.
