Newmarket Gold Announces Positive Preliminary Economic Assessment for the 100% Owned Maud Creek Gold Project - Pre-Tax NPV5% of AUD$201 Million

Pre-tax IRR of 116% and Pre-Production Capex of AUD$42 Million

VANCOUVER, BRITISH COLUMBIA--(Marketwired - May 16, 2016) - Newmarket Gold Inc. ("Newmarket" or the "Company") (TSX:NMI) (OTCQX:NMKTF) is pleased to announce the results of a Preliminary Economic Assessment ("PEA") prepared in accordance with National Instrument ("NI") 43-101 on the Company's 100%-owned Maud Creek Gold Project ("Maud Creek") in the Northern Territory, Australia. The Maud Creek PEA was prepared by SRK Consulting (Australasia) Pty Ltd ("SRK") and provides a base case for processing gold mineralization from conventional open pit and underground mining methods, through the use of Newmarket's permitted and operating Union Reefs Processing Facility. The NI 43-101 technical report for Maud Creek entitled "Technical Report, Preliminary Economic Assessment of the Maud Creek Gold Project, Northern Territory, Australia" and dated May 16, 2016 (the "Technical Report") will be available today under Newmarket's profile on SEDAR at and on its website at

All figures are stated in Australian Dollars ("AUD$") unless otherwise noted.


Base case parameters assume a gold price of AUD$1,550/oz (US$1,200) and an exchange rate (US to AUD) of 0.77.

  • Pre-Tax Net Present Value at a 5% discount rate ("NPV5%") of AUD$201 million (US$155 million) and Internal Rate of Return ("IRR") of 116% with a 1.25 year payback period.
  • After-tax NPV5% of AUD$137 million (US$105 million) and IRR of 80% and a 1.25 year payback period.
  • Mine life of 9.5 years with average annual gold production of 52,000 ounces and peak annual gold production of approximately 70,000 ounces.
  • Total recovered gold of 496,000 ounces.
  • Life of mine ("LOM") diluted head grade of 4.2 g/t Au.
  • Pre-production capital cost estimated at AUD$42 million (US$32 million).
  • LOM cash operating cost estimate of AUD$1,101/oz (US$847/oz) and LOM capital cost of AUD$113/oz.

Douglas Forster, President and CEO of Newmarket stated that "The Maud Creek PEA base case provides Newmarket with the potential to increase the utilization of the Union Reefs Processing Facility, which has the capacity to process 2 million tonnes per annum, and is currently processing ore from the Cosmo Underground Gold Mine at a rate of approximately 800,000 tonnes per year. The Maud Creek deposit is located close to existing infrastructure such as road and rail networks and is also situated approximately 20 km from the regional centre of Katherine in the Northern Territory. The positive results of the PEA at our 100% owned Maud Creek project provides additional flexibility for Newmarket's Northern Territory Operations in addition to the current mill feed being provided by the Cosmo Mine. The benefits of the Union Reefs Processing option includes the ability to realize value from the oxide gold mineralization mined through open pit mining and the fresh sulphide mineralization from underground mining methods and low capital cost for modification of the existing operating Union Reefs Processing Facility."

The PEA is preliminary in nature and is based on a number of assumptions that may be changed in the future as additional information becomes available. The PEA includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the PEA will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability.


The PEA, examined the processing of gold mineralization at Newmarket's Union Reefs Processing Facility, located 144km from the Maud Creek Project via an existing major roadway, (including oxide mineralization), and through a stand-alone plant, constructed on-site at Maud Creek (excluding oxide mineralization), to produce a saleable gold concentrate and gold Dore. Based on the results of the comparison of the economic and infrastructure considerations associated with both options, the Union Reefs Processing Facility is the preferred option.

The PEA is based on oxide and sulphide gold mineralization at Maud Creek, mined by a combination of open pit and underground mining methods, and trucked using quad semi-trailers to Newmarket's existing operating and permitted processing plant at Union Reefs.

The mine has a 9.5 year operating life, including 2 years of open pit operations prior to commencing underground production. The Maud Creek deposit remains open down-plunge and with additional drilling it may be possible to extend the mine life of the operation. The maximum depth of the underground is 500 metres below surface with the current open pit/ underground transition at 125 metres below surface.

The Maud Creek Project After tax financial model has incorporated Australian Federal Tax at a rate of 30% and the Northern Territory Royalty Tax of 20%. Newmarket Gold NT Holdings Pty Ltd., the owner of the Maud Creek Gold Project and wholly owned subsidiary of Newmarket, carries estimated tax losses as follows as at December 31, 2015, which have not been included in the economic analysis:

Income tax non-capital losses AUD$229.8 million
NT Royalty Tax Net Negative Value AUD$151.0 million

Based on the integration of the Maud Creek Project with existing infrastructure and Northern Territory production unit, the NT Royalty Net Negative Value has the potential to positively impact the value of the Maud Creek Project if determined to be applicable. The NT Royalty Tax of 20% in the financial model equates to a cost of AUD$107 per ounce.

Mineral Resource

The Maud Creek Mineral Resource estimates presented in Tables 3 and 4 below, prepared by SRK, are based upon 97 diamond drill holes and 442 reverse circulation percussion holes totalling 74,993 metres drilled over a 22 year period. SRK undertook a thorough examination of all available information. The Mineral Resource was estimated using Ordinary Kriging within six domains.

Capital Costs

Pre-production capital costs are estimated at AUD$42 million with the majority of the costs associated with the inclusion of a sulphide circuit at the Union Reefs Processing Plant and capitalised mine development for access.

Open Pit and Underground mining operations are proposed to be undertaken by contract mining, as is conducted at Newmarket's existing NT operations at the Cosmo mine. AUD$7.3 million has been allocated for surface works associated with diversion of the ephemeral creek and water management and treatment infrastructure. Additional work is required to further define the technical requirements and the capital requirements. Table 5 below outlines the PEA capital cost estimates.

The PEA mine plan is based upon conventional open pit mining followed by a transition to underground mining where conventional long-hole open stoping utilising cemented rock and waste fill will be used. The absence of suitable data has led to low-confidence in the geotechnical conditions. Additional data is required to improve confidence and refine decisions on mining methods and the mine design. The mining method studies are linked to the decision on the location of the Processing Plant and the availability of pastefill.

* Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. All figures have been rounded to reflect the relative accuracy of the estimates. Initial disclosure of Mineral Resources is reported at a cut-off grade of 2.6 g/t Au based on AUD1,415 per ounce gold, gold metallurgical recoveries of 85% for oxide and transitional mineralization and 95% for fresh mineralization.

All mine development would be performed by mining contractor using conventional electric-hydraulic drilling equipment and suitable sized diesel-powered LHD loaders and haul trucks. All mine manpower except for technical and support staff would be contracted employees.


Due to the limited electrical power demand for the underground mining operation of 2.0 MW power will be provided via on-site diesel generators supplied, owned and operated by an independent power provider (IPP). Power at the Union Reefs Processing Plant is supplied via the 66 kV Darwin-Katherine distribution network. There is sufficient power capacity to meet the modifications to the Union Reefs facility for processing the Maud Creek mineralization.


An extensive program of metallurgical testing was carried out on the Maud Creek Project from 1994 through to 2006 at reputable and suitably experienced laboratories. The PEA proposes processing Maud Creek oxide mineralization through the existing Union Reefs Carbon-In Leach processing plant. The transitional mineralization feed, which makes up just a small portion of the overall LOM tonnage is a significant part of the first years feed, will have more variable metallurgical behaviour. Transitional mineralization can be processed through the existing oxide circuit and/or the new flotation circuit to optimize recovery. The base case presented for this study contemplates the addition of flotation and concentrate dewatering circuit's to the existing Union Reefs processing facility to process fresh, sulphide mineralization, the bulk of the project tonnage, producing a gold-sulphide concentrate for sale. A gravity gold concentrate will also be produced with 20% of the gold being recovered by gravity. The concentrate will be dewatered through thickening and filtration before being bagged, stored in shipping containers and transported by road, then shipped to customers in China.

The PEA reviewed the previous metallurgical testwork data and supporting engineering studies and proposes a conventional, inexpensive and low-risk processing circuit allowing flexibility with respect to circuit configuration and downstream processing. Based on the historical testwork, a total gold recovery of the fresh sulphide material of 95% was applied and a total recovery of 85% was applied for the oxide/ transitional material. Further work is required to fully integrate the proposed sulphide circuit and determine the optimum processing configurations.

Project Opportunities

The PEA supports that Maud Creek has the potential to significantly positively impact Newmarket's Northern Territory Operations, which currently operate the Cosmo Underground Gold Mine with processing of ore through the Union Reefs Processing Facility. The processing facility is currently processing approximately 800,000 tonnes per annum of Cosmo ore and retains the capacity to include additional material mined from the Maud Creek project.

The Maud Creek deposit also remains open down-plunge and with additional drilling it may be possible to extend the mine life of this operation. Newmarket believes that there is an opportunity to increase the mine life through targeted exploration.

The PEA is part of a phased Feasibility Study agreement in place between Newmarket and SRK, which provides Newmarket with the option to proceed to Pre-Feasibility and Feasibility stages now that the PEA has been completed. Such future stages would further consider geotechnical and geometallurgical modelling of the Maud Creek Project, additional review of the metallurgical testwork completed on the Maud Creek deposit, and confirmation of capital required to upgrade the Union Reefs Processing Facility. Future stages may also include further drilling, with the potential to increase the Mineral Resource base of the deposit.
