Rubicon Minerals Provides Construction and Development Update on the Phoenix Gold Project
TSX:RMX | NYSE.MKT:RBY
TORONTO, Jan. 28, 2013 /PRNewswire/ - Rubicon Minerals Corporation (TSX: RMX | NYSE-MKT: RBY) ("Rubicon" or the "Company") provides an update on the construction and development of the Phoenix Gold Project.
Phoenix Gold Project Development1
The Company continues to make good progress with the sinking of the shaft. As of today, the shaft bottom is at 610 metres ("m") below surface. Contractor crews are currently excavating the 610 m level station. During November and December of 2012, the Company encountered unfavourable ground conditions that impacted the rate of development. Ground conditions have improved significantly in January 2013. Shaft sinking continues and the Company expects better development rates going forward. The Company continues to evaluate the economics of the shaft extension and its use for further resource identification.
Mill and Carbon-in-Leach ("CIL") Plant Construction
The mill CIL building foundation has been completed, as well as the erection of the steel framework. The Company continues construction of the remaining mill building foundation. Subject to the Company's ongoing progress and evaluation of the construction and development of the Phoenix Gold Project, the delivery of long lead time items, such as the "SAG" (semi-autogenous grinding) and ball mills, remain on schedule, consistent with the Company's current proposed timeline. The selection and procurement of the processing equipment is ongoing. The Company plans to complete the mill construction in the second quarter of 20141.
Updated Mineral Resource
Rubicon plans to complete and release the summary of its updated mineral resource at the end of the first quarter of this year. The report will include data from over 100,000 m of core drilling since late 2011.
Optimization of the PEA2
The Company continues to prepare and review studies on the optimization of the existing preliminary economic assessment ("PEA")2 released in August 2011. The purpose is to evaluate different mining scenarios to refine and improve the currently proposed mining plan and economics. These scenarios are sensitive to the updated mineral resource estimate, and the current economic climate. There are several key areas in the PEA2 where the Company is looking to optimize:
Mining method: The Company is considering the longhole stoping mining ("longhole") method instead of, or to supplement, the cut-and-fill method. The
Company believes that the longhole method is more productive, can lower
operating cost, and is not meaningfully dilutive to the mined grade.
The longhole method uses more mechanized equipment, which could add to
the capital requirements.
Infrastructure and development layout: Rubicon is considering increasing the vertical interval between the
main levels to 120 m (as compared to 60 m in the PEA2) and developing a ramp to interconnect the levels. The Company believes
this different layout allows for efficient movement of equipment,
material, and personnel between levels. The Company also believes that
the capital cost savings from developing fewer levels will partially
offset the capital cost of the ramp.
Equipment: The Company is assessing the use of modern "LHD" (load haul dump)
loaders and haulage trucks, using a combination of diesel-fueled and
battery-operated units. Rubicon believes using mechanized equipment
versus rail-mounted cars and mucking machines is more productive and
provides flexibility. Furthermore, battery-operated LHD loaders and
trucks do not produce emissions, are cleaner for the environment, and
reduce capital costs for ventilation infrastructure. The gold-bearing
material would be transferred between levels by gravity through
internal ore passes.
Throughput: The Company is evaluating an increase in throughput at an average rate
higher than the 1,250 "tpd" (tonnes per day) rate in order to increase
the output in ounces.
Shaft depth: Rubicon is extending the depth of the shaft below 610 m for improved
access to more potential mining areas.
- Exploration platform: The Company is assessing constructing deep, underground, exploration platforms that allow step-out drilling below the 1,200 m depth with shorter drill holes. This would allow the Company to follow up on higher grade intercepts and potentially increase the mineral resource at depth.
The Company has commissioned SRK Consulting ("SRK") to conduct the updated mineral resource estimate and optimization studies.
"Our objective is to optimize the Phoenix Gold Project to make it the best it can be," said Mike Lalonde, President and Chief Executive Officer of Rubicon. "We recently made senior management changes to strengthen our project team. The SRK group that will be involved on the Phoenix Gold Project have been integral in the optimization and mine planning of Goldcorp's Cochenour Project in Red Lake. They have extensive experience working with narrow-vein, lode gold deposits. SRK will add additional strength to complement the project team."
The optimization studies are scheduled to be completed in the second quarter of this year. The Company believes that the new methods being considered in the optimization studies will potentially improve the efficiency and productivity of the Phoenix Gold project. However, the implementation of the new methods would likely increase the initial capital cost of developing the Phoenix Gold project compared to the $214 million outlined in the PEA2. Rubicon is not able to provide an accurate estimate of the capital cost increase for the Phoenix Gold Project prior to the completion of these studies. Management plans to evaluate financing alternatives upon the completion of the optimization studies, to address any potential increase in the capital cost of the Phoenix Gold project.
Timeline to Potential Production
Based on achieving the current scheduled milestones, and subject to the Company's ongoing progress and evaluation of the construction and development of the Phoenix Gold Project, the timeline to potential production would be the second half of 2014.
As of December 31, 2012, Rubicon has approximately $171 million in cash and cash equivalents, and investments, and approximately $157 million in working capital. Approximately $85 Million has been spent on the project to date.

1 The Company continues to consider a number of factors in connection with the ongoing progress and evaluation of the construction, development and potential production of the Phoenix Gold Project, which will include, when available, the results from the mineral resource update and the ongoing optimization studies on the PEA2, as well as project financing opportunities and development timelines.
2 The PEA is preliminary in nature as it 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 estimate of mineral resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues. The quantity and grade of reported inferred resources referred to in the PEA are uncertain in nature and there has been insufficient exploration to define these inferred resources as an indicated or measured mineral resource category. The PEA is a technical report under NI 43-101, was prepared by AMC Mining Consultants with metallurgical and processing contributions from Soutex Inc., and has an effective date of August 8, 2011.
Phoenix Gold Project site operations are conducted under the supervision of Mike Lalonde, P.Eng., President & CEO for Rubicon and a Qualified Person as defined by NI 43-101, who approved the contents of this release.
