THUNDER BAY, ONTARIO--(Marketwired - Aug 1, 2013) - Mega Precious Metals Inc. (TSX VENTURE:MGP) ("Mega") announces that, further to the news release of June 17, 2013, Mega has filed the National Instrument 43-101 Technical Report entitled "Technical Report and Resource Estimate Update on the Monument Bay Project, Northern Manitoba" dated August 1, 2013, on SEDAR at www.sedar.com. The report has also been posted on the Company's website at www.megapmi.com. There is no material differences between the results of the Technical Report filed today and the disclosure provided in the June 17, 2013 news release.

The resource estimate has been completed by Tetra Tech which demonstrates a significant improvement in the size, grade distribution and confidence from the previous resource estimate (See news release dated February 22, 2012).

Highlights of our new mineral resource estimate include:

  • Measured and Indicated Resources of 2.9 M Ounces of Gold at 1.3 g/t Au
    • Upgrading 1.8 M ounces in classification, an overall increase of 94% from the previous resource estimate.
  • Inferred Resources of 0.7 M Ounces of Gold
  • High Grade Starter Pit providing optionality, flexibility and potential rapid payback
    • Monument Bay is estimated to contain a distinct, higher-grade Measured and Indicated open-pit resource of 667,308 ounces of gold averaging 2.7 g/t Au at a 1.5 g/t Au cut-off
  • Over 143,460 m of drilling, plus channel sampling and surface mapping incorporated into the geological model
    • Includes over 32,500 m of drilling since the last resource update
  • Improved Confidence in the Twin Lakes Open Pit deposit with 91% of the resource in the Measured and Indicated category
  • Additional Unconstrained Open-pit Resources at the Expanding Mid East and AZ Zones increasing total Measured and Indicated resources to 80,084 ounces of gold and Inferred resources to 312,361 ounces of gold.
  • Defined Repeatable Cores every 180-290 m that are consistent and predictable continue along strike and depth providing potential for significant resource expansion

  • Mineral resources which are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, socio-political, marketing, or other relevant issues.
    • The 2013 mineral resource estimate is based on the combination of geological modeling, geostatistics and Ordinary Krig grade estimation within three-dimensional block models with mineralized domains defined by wireframe solids.
    • The QA/QC protocol and corresponding sample preparation, shipment procedures and analytical procedures have been reviewed by Tetra Tech.

All composites have been capped where appropriate. Cut-off grades are based on a price of US$1,372 per ounce of gold and a number of operating cost and recovery assumptions (see details below).

Sensitivity Analysis

The Updated Resource Estimate represents a rigorous evaluation of both the 2012 drilling (40 holes and over 12,500 m plus 20,000 m from the old core assay program (OCAP) in addition to the inclusion of all of the surface mapping/sampling programs and the University of Manitoba Research Program completed to the end of January 2013. The Updated Resource Estimate was constrained in a preliminary open-pit optimized shell (Datamine NPV Scheduler) to an average Depth of 380 m. For the purpose of this news release, the Pit constrained resource estimate is reported at a cut-off grade of 0.7 g/t Au and for Underground a cut-off grade of 4.0 g/t Au was used. Both cut-offs were chosen to better represent the higher-grade core to the mineralized zone and to provide continuity for future resource estimates and a Preliminary Economic Assessment ("PEA") when and if the Corporation deems it appropriate.

The most noticeable difference from previous estimates is the significant increase in the size and overall persistent higher grade nature of the deposit at different cut-offs (Table 2), due to the combination of the OCAP, infill drilling programs, surface exploration and University of Manitoba research program. As such the corporation's understanding of the Monument Bay Gold Project is improving with each resource estimate and it is now recognized that each deposit has repeatable higher-grade cores along with a strong tungsten correlation providing the components needed to increase the grade and growing the overall resource. At a 1.0 g/t Au cut-off, the resource contains a significant deposit of greater than 1.8 g/t average gold grades.

Tables 2 and 3 below present the tonnes and grades from the block model used for the Mineral Resource Estimate at a range of cut-off grades in order to demonstrate the sensitivity of the estimates. The analysis indicates the robust nature of the overall resource and potential to optimize the grade and maximize margins.

The cut-off value of 0.7 g/t Au for potential open pit and 4.0 g/t Au for deeper, potential underground mineralization was derived using the parameters listed in Table 4 below.

As a comparison, if we use a gold price of $1300 USD our cut-off value for the potential open pit would increase to 0.8 g/t and the potential underground would stay at 4.0 Au g/t cut-off. This would translate into a resource of 2.5 M Measured and Indicated pit constrained gold ounces and the Inferred would be 0.3 M pit constrained gold ounces. If we used a gold price of $1,400 USD our cut-off value for the potential open pit would decrease to 0.6 g/t and the potential underground would stay at 4.0 Au g/t cut-off. This would translate into a resource of 3.1 M Measured and Indicated pit constrained gold ounces and the Inferred would be 0.3 M pit constrained gold ounces.

The mineral resource estimates used the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by CIM Standing Committee on Reserve Definitions and adopted by CIM Council on November 27, 2010. The mineral resource estimates are classified as "measured", "indicated", or "inferred" as defined by CIM. The Corporation intends to file a National Instrument 43-101 ("NI 43-101") compliant technical report in respect of the updated mineral resource estimate on SEDAR and on the Corporation's website within 45 days of this news release.

According to the CIM definitions, a Mineral Resource must be potentially economic in that it must be "in such form and quantity and of such grade or quality that it has reasonable prospects for economic extraction".

The quantity and grade of reported inferred resources in this estimation are uncertain in nature and there has been insufficient exploration to define these inferred resources as an indicated or measured mineral resource and it is uncertain if further exploration will result in upgrading them to an indicated or measured mineral resource category.

Technical Discussion and Analysis

The currently announced resource represents the first consolidated statement of three deposits comprising the 100%-owned Monument Bay Gold Project. The Twin Lakes Deposit represents 96% of the total Measured and Indicated (M+I) ounces and 41% of the total Inferred ounces.

Some choices (and changes) have been made in completing the estimation in June 2013 estimate that Mega believes results in an improved overall resource estimate. Some of these include:

  • Revised Geological Model using domain modeling and improved understanding of the geological setting
  • Cut-off grades
  • Revised block sizes for underground (U/G) and open pit (O/P) material at the deposits
  • Inclusion of detailed surface mapping/sampling
  • Inclusion of University of Manitoba related research

The aggregate impact of these choices and adjustments has resulted in a 138% increase of M+I and 92% Inferred ounces reported at Twin Lakes O/P Deposit. These changes do not include the addition of tungsten as a gold equivalent. Tungsten assays to date are increasing the gold equivalent grade of the drill hole samples by an average of 32% (See news release dated Feb 25, 2013).

In Mega's opinion, this change to the quality of the ounces is a significant improvement in how the block model reflects the data and in-situ mineralization both locally and regionally.

Monument Bay Gold Project is located 52 kms north of Red Sucker First Nation located on Red Sucker Lake, Manitoba. The property is located on Crown property in an area of low topographic relief and outcrop is fairly rare. Manitoba's Current Northern Development Strategy is building all-purpose roads and infrastructure improvements within the region. Once these are complete, we will have all purpose roads and power lines that are within approximately 52 kms of our project area.

All of the open pit mineralization has been identified where mineralized gold/tungsten bearing veins come to surface/near surface and the underground component consists of veins that are the continuation of these veins below the conceptual open pit.

The Mid East deposit is located on the same gold/tungsten bearing structure, approximately 2 kms to the east of the Twin Lakes Deposit and the AZ Zone is located on a parallel structure that is less than 300 m to the south of the Twin Lakes Deposit. Both of these deposits are surface/near surface deposits and may be amenable to being evaluated as an open pit mining resource. Mega currently regards the Mid-East and AZ Zone deposits as early stage resources with potential to grow. Their proximity to the Twin Lakes Deposit may be beneficial to any potential future development at these sites.

All of the deposits remain open both along strike and down-plunge and new prospective horizons located in close proximity to the current resource are currently being further defined by drilling, OCAP, and surface exploration which will provide valuable information to make additional new discoveries.
