New Carolin Gold Announces Positive Preliminary Economic Assessment of the Tailings Reclamation Project

VANCOUVER, BRITISH COLUMBIA–(Marketwire – March 14, 2012) –


New Carolin Gold Corp. (TSX VENTURE:LAD) is pleased to announce the results of the Preliminary Economic Assessment (PEA) for the Tailings Reclamation Project at its Ladner Gold Property in British Columbia.

The study recommends that the project be built as a portable mill operation producing a saleable concentrate. The mill will be built using industry standard equipment and processing systems to minimize technical and operational risks.


  • A projected best case scenario is an estimated NPV (at 5% discount) of $8,000,000 with an IRR of 35% for a seasonal 60 month project life at a milling rate of 400 tpd, based on a gold price of US$1,100 per oz and a US$:CDN$ exchange rate of 1:1.
  • Royalty range of 20 to 30%
  • Capital costs are estimated at $8.3 million +/- 35% in Q4 2011 dollars.
  • Life of Mine ("LOM") onsite cash operating costs are estimated at CDN$3.5 million.
  • The project as designed is expected to produce a total of 24,483 ounces of gold contained in concentrate.
  • The PEA is based on the NI 43-101 resource study which delineated an Indicated Mineral Resource estimate of 23,700 oz gold in 445,378 tons at a cutoff grade of 1.00 gm/t gold and an Inferred Mineral Resource estimate of 5,000 oz gold in 93,304 tons at a cutoff grade of 1.00 gm/t gold (see press release of November 9, 2011).

The PEA is an important milestone for the Ladner Gold Project for the following reasons:

  • Provides early cash flow to the Company,
  • Provides more space in the impoundment anticipating startup of the former Carolin Mine,
  • Provides a potential byproduct of tailings sands that could be used as borrow material and
  • Initiates operational approval necessary for updating permits for the mine.


The PEA indicates the economic returns from the project justify development of the Tailings Reclamation Project. The financial results of the assessment ("Base Case") were developed using gold commodity price of US $1,100 per oz and a discount rate of 5.0%. The gold price was considered reasonable given the current industry estimate of USD $1,100 per oz as a long term price. The gold in concentrate is the realized saleable gold concentrate.

Base Case using USD $600/oz (gold in concentrate) and exchange rate USD:CDN as 1:1

Initial Capital Investment CDN $8,300,000
Payback period 60 months
Mill operation 60 months
IRR 5.20%
NPV (5% discount) CDN $50,000
Mill throughput 400 tons per day
Mill feed grade 1.80 gms/ton
Recovery 85%
Tailings Resource 23,700 oz gold
5,000 oz gold

Comparison of alternative scenarios using adjusted "gold in concentrate".

CASE Gold (USD/oz) NPV at 5% discount IRR
Base Case $600 $50,000 5.20%
Scenario 1 $625 $450,000 6.90%
Scenario 2 $1,100 $8,000,000 35.30%


The total initial capital investment in the project is estimated to be CDN $8.3 million, which represents the total direct and indirect costs, including associated infrastructure and contingencies based on a 35% margin of error. The Base Case presented in the PEA is designed to allow for the worst case scenario, however it is anticipated that the gold price will be higher and the contingency will be less than 35%.

The NI 43-101 resource study delineated an Indicated Mineral Resource estimate of 23,700 oz gold in 445,378 tons at a cutoff grade of 1.00 gm/t gold and an Inferred Mineral Resource estimate of 5,000 oz gold in 93,304 tons at a cutoff grade of 1.00 gm/t gold (see press release of November 9, 2011). Additional resource potential exists as the resource estimate accounts for approximately 60% of the drilled area within the tailings impoundment and additional drilling will be needed to determine the full extent of the gold resource. Mineral resources that are not mineral reserves do not have demonstrated economic viability.

The PEA evaluates the development of the tailings by conventional recovery methods, using slurry pumps and portable processing equipment. The permitted tailings impoundment has been monitored and inspected by independent consulting engineers and is in excellent condition.

The portable plant design is based on a single line flow sheet employing flotation, regrinding, thickening and filtering to produce a concentrate for export averaging 19.0 gm/t gold. The primary and regrind product sizes and flotation parameters were determined by metallurgical test work. While the test work indicates that the concentrate contains some arsenic, a penalty for the arsenic has been taken into account.

Water from the tailings slurry will be reclaimed for use in the milling process, however there will be some excess water discharge. A water treatment plant has been included in the process to ensure that the water quality conforms to all provincial water quality guidelines.

Mine infrastructure includes upgrading of an existing forest access road over a distance of approximately 10km. There is no need for camp facilities as most of the mine and plant operating and maintenance labour is expected to be drawn from the Hope area which is approximately 18 km to the south.

The tailings process facility will be operated under a sub-contractor agreement and that the Company will be paid a royalty. Following the processing of the gold resources contained in the tailings, the tailings impoundment will be used in conjunction with the proposed underground and open pit mine development and processing in the upgraded onsite mill facility.


The economics of the PEA do not take into account opportunities for future improvement based on:

  • Varying the mill throughput.
  • Further development of the PEA process flowsheet to increase the level of gold contained in the processed concentrate.
  • Potential for payable silver in the concentrate
  • Improved metallurgical performance
  • Shared access development cost

Future Work Program

Management's plans for 2012 are:

  • Complete and submit the various applications for operational permitting,
  • Continue water sampling of the tailings impoundment and surrounding area,
  • Investigate and implement opportunities for improvement in project economics, and
  • Proceed with financing and strategic partnership discussions with interested parties.
