AURIGA GOLD CORP. ANNOUNCES UPDATED GOLD MINERAL RESOURCE ON ITS MAVERICK GOLD PROJECT: TOTAL MEASURED AND INDICATED MINERAL RESOURCES INCREASED BY 88% TO 327,900 OUNCES OF GOLD

Auriga Gold Corp. has released an updated independent National Instrument 43-101 mineral resource estimate for the Puffy Lake gold deposit and an initial NI 43-101 mineral resource estimate for the Nokomis gold deposit, both located on its 100-per-cent-owned Maverick gold project, located 65 kilometres north of Flin Flon, Man.

Together, the Puffy Lake and Nokomis gold deposits support mineral resources amenable to open-pit and underground mining that include measured and indicated mineral resources totalling 327,900 ounces of gold and inferred mineral resources of 438,600 ounces of gold (see attached resource summary table).

Highlights for the Puffy Lake deposit are:

  • In-pit measured and indicated mineral resource increased by 151 per cent to 80,400 ounces from 32,000 ounces;
  • In-pit measured and indicated gold grade increased by 6 per cent to 4.4 grams per tonne gold from 4.16 grams per tonne gold;
  • Underground measured and indicated mineral resource increased by 46 per cent to 206,800 ounces gold from 142,000 ounces gold;
  • Underground measured and indicated gold grade decreases by 6 per cent to 5.93 grams per tonne gold from 6.29 grams per tonne gold;
  • Total Puffy Lake deposit inferred mineral resources decreased modestly to 419,500 ounces gold from 558,000 ounces gold, mostly as a result of being converted to measured and indicated category.

The initial NI 43-101 mineral resource estimate for the Nokomis gold deposit is the first step toward including this significant shallow mineral resource into an updated preliminary economic assessment. The Nokomis mineral resource is amenable to open-pit mining, and is located just eight kilometres from the existing mine and mill infrastructure on the Maverick gold project. Management believes this Nokomis mineral resource estimate could enhance the earlier preliminary economic assessment, which was based solely on the Puffy Lake deposit and an operating rate of 750 tonnes per day versus the nameplate capacity of the mill, which is 1,000 tonnes per day.

Highlights for the Nokomis gold deposit are:

  • Indicated mineral resource of 40,700 ounces;
  • Indicated grade of 3.41 grams per tonne gold;
  • Inferred resource of 19,100 ounces of gold.

Both the Puffy Lake and Nokomis deposits remain open at depth.

The company will file an NI 43-101 technical report on SEDAR within 45 days.

Gorden Glenn, president and chief executive officer, commented: "The purpose of this mineral resource update for the Puffy Lake deposit was to incorporate 45 holes drilled subsequent to the August, 2011, initial NI 43-101 mineral resource estimate, and confirm management's expectation for a significant conversion of mineral resources previously categorized as inferred to the higher confidence measured and indicated category. The initial NI 43-101 mineral resource estimate for Nokomis will enable us to incorporate its significant in-pit mineral resource into our updated PEA. We are very pleased with the high proportion of inferred mineral resource that was successfully converted to measured and indicated at Puffy Lake. We are also pleased with the significant increase in total in-pit measured and indicated category mineral resources."

Notes: 
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, taxation, socio-political, marketing, or other relevant issues. 
(1) 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.
(2) The Puffy Lake updated NI 43-101-compliant mineral resource estimate has been 
prepared by Eugene Puritch, PEng, of P&E Mining Consultants Inc. The Nokomis 
NI 43-101-compliant mineral resource was prepared by Leon McGarry, BSc, PGeo, of 
ACA Howe International Ltd. 
(3) The NI 43-101-compliant mineral resources in this press release were estimated 
using the Canadian Institute of Mining, Metallurgy and Petroleum standards on 
mineral resources and reserves, definitions and guidelines prepared by the 
CIM standing committee on reserve definitions and adopted by the CIM council. 
(4) Grade capping of 30 grams per tonne gold was utilized on composites at the 
Puffy Lake deposit and grade capping of 50 grams per tonne gold was utilized on 
raw assays at the Nokomis deposit. 
(5) Bulk densities of 2.72 tonnes per cubic metre and 2.89 tonnes per cubic metre,
respectively, were used for tonnage calculations at the Puffy Lake deposit and 
Nokomis deposit, respectively. 
(6) At the Puffy Lake gold deposit, open-pit resources are reported within an 
optimized pit shell.
(7) A gold price of $1,300 (U.S.) per ounce and an exchange rate of 
97 U.S. cents to $1 (Canadian) was utilized in the gold-cut-off-grade 
calculations of 0.6 gram per tonne open pit and 2.5 grams per tonne underground. 
Open-pit mining costs were $3.75 per tonne for mineralized material and $3 per tonne
for waste rock, while underground mining costs were $75 per tonne. Process costs 
were $17 per tonne, and general and administrative costs were $6 per tonne. 
Process recovery used was 95 per cent.

The updated mineral resource estimate for the Puffy Lake deposit is based on a substantial drill hole database consisting of 390 diamond holes, including:

  • 90 holes drilled by Auriga Gold between 2011 and 2013;
  • 300 holes by previous operators drilled prior to 2010.

The initial NI 43-101 mineral resource estimate for Nokomis includes prior drilling as follows:

  • 19 Auriga diamond drill holes completed in 2012 (A4-01 to A4-19);
  • 125 historic diamond drill holes completed between 1958 and 2005;
    • 20 Claude/Pioneer diamond drill holes completed in 2004 (04-106 to 04-108) and 2005 (05-110 to 05-125);
    • 20 Pioneer diamond drill holes completed in 2000 (00-97 to 00-105) and 1997 (97-86 to 97-96);
    • 39 Dome diamond drill holes completed in 1985 (61 to 85) and 1975 (47 to 60);
    • 41 Rio Tinto diamond drill holes completed in 1961 (holes 6 to 46);
    • Five Parres diamond drill holes completed in 1958 (holes 1 to 5).

As previously disclosed, the company is diligently working toward a positive mine restart decision for the Maverick gold project. The completion of updated and initial NI 43-101 mineral resource estimates for Puffy Lake and Nokomis deposits, respectively, is an integral step in the company's technical program to derisk the Maverick gold project. The company can now look forward to developing a new underground mine plan utilizing the Minrail Inc.'s SAMS technology and developing a new open-pit mine plan that will form the basis of the updated preliminary economic assessment that the company hopes to have completed before the end of June 2014.

With respect to the underground mine plan, the resource update for the Puffy Lake gold deposit is material step forward in the company's overall work program. With the resource block model in hand, the company is pleased to report its underground mine plan consultant, Minrail, has already made significant progress developing not only a new underground mine plan but also a program for an underground test mine stope that the company hopes to initiate in the second half of 2014. This stage of the project is another important part of the company's systematic program to derisking the Maverick gold project. The company intends to initiate the underground test mining soon after the completion of the updated preliminary economic assessment and is in the process of making plans to dewater the decline to gain access to near-surface test stopes. The test mining stope will enable management and consultants to:

  • Confirm grade, thickness and continuity of the mineralized veins in the test stope;
  • Confirm the viability of the proposed SAMS;
  • Confirm SAMS development and operating costs;
  • Confirm and assess underground geotechnical and hydrogeological conditions;
  • Provide a large bulk sample for additional metallurgical testing.

Upon the completion of the proposed underground test mining program, the company hopes to be in a position to conclude its financing arrangements and advance the Maverick gold project to full production in 2015.

The Maverick gold project mineral resource information presented in this release has been reviewed and approved by Eugene Puritch, PEng, of P&E Mining Consultants and Leon McGarry, BSc, PGeo, of ACA Howe International of Toronto, Ont. Mr. Puritch and Mr. McGarry are independent qualified persons as defined under NI 43-101 regulations.

We seek Safe Harbor.
