Colossus Minerals Provides Development Update

07/15/2013

TORONTO, ONTARIO--(Marketwired - July 15, 2013) - Colossus Minerals Inc. (the "Company" or "Colossus") (TSX:CSI)(OTCQX:COLUF) provides a development update for its 75% owned Serra Pelada gold-platinum-palladium Mine. The Serra Pelada Mine is a joint venture between Colossus and Cooperativa de Mineração dos Garimpeiros de Serra Pelada ("COOMIGASP") located in the State of Pará, Brazil.

HIGHLIGHTS

  • Mining has progressed through the CMZ with both water and ground conditions being managed. However, recently some dewatering wells and pumps have not performed to design specifications. As a result, the Company has determined that additional dewatering capacity, which is currently being brought on line, is required to mine the CMZ in a sustainable, effective and efficient manner.



  • As a result, mining activity through the Central Mineralized Zone ("CMZ") has been delayed and resources have been re-deployed to focus on infrastructure development and additional dewatering in order to keep the Company's plans of achieving 1,000 tonnes per day ("tpd") in the first quarter of 2014 intact. Infrastructure development in the red and gray siltstone is not impacted.



  • The Company now anticipates a delay in gold production from the mine until late in the fourth quarter of 2013.



  • Management is currently evaluating the amount and timing of additional funds required to address the impact of the delay in the ramp-up and otherwise continue development and construction of the Serra Pelada Mine.



  • Underground development continues in the red and gray siltstone at better than anticipated daily development rates with three headings (main decline, ventilation expansion and northern mineralization access) currently being developed. The Company will continue developing mine infrastructure and expects to end the year with five access drifts ready to enter the CMZ late in the fourth quarter to commence production at 500 tpd.



  • The ventilation expansion project remains on schedule.



  • The Company anticipates commissioning the mill commencing in the third quarter with surface stockpiles of approximately 3,000 tonnes collected during the bulk sample program.



  • Process plant construction is currently 87% complete. Structural steel erection is now 85% complete. Commissioning of the plant remains on schedule for later in the third quarter.



Claudio Mancuso , Chief Executive Officer commented, "Although the Company has managed ground conditions and water, the Company has determined additional dewatering capacity is required to mine the CMZ in a safe, sustainable, effective and efficient manner. Additional dewatering capacity has recently been brought on-line with additional capacity being mobilized continuously over the next 60 days. Although the Company has changed its mine plan and ramp-up schedule, management is confident that the additional dewatering capacity will enable the Company to achieve its plan of processing 1,000 tpd by the end of the first quarter of 2014."

CONSTRUCTION AND DEVELOPMENT ACTIVITIES

Underground Development

  • Mining has progressed through the CMZ with both water and ground conditions being managed. However, recently some dewatering wells and pumps have not performed to design specifications. As a result, the Company has determined that additional dewatering capacity, which is currently being brought on line, is required to mine the CMZ in a sustainable, effective and efficient manner.



  • As a result, mining activity through the CMZ has been delayed and resources have been re-deployed to focus on infrastructure development and additional dewatering in order to keep the Company's plans of achieving 1,000 tpd in the first quarter of 2014 intact. Infrastructure development in the red and gray siltstone is not impacted.



  • The Company now anticipates a delay in gold production from the mine until late in the fourth quarter of 2013.



  • The Company continues to make progress in its mine planning activities and has laid out (in the attached pictorial update) the month by month development which will take place between now and the end of 2013.



  • The Company plans to continue the decline development to have multiple horizons ready for mining in 2014, continue with the ventilation upgrade and prepare five access drives to commence production late in the fourth quarter of 2013.



  • The Company is currently fast-tracking its dewatering program expansion.



  • Technical services to support continued advancement of the mining program are in place and are currently being supported by Hatch engineering.



  • The ventilation expansion program is now in excess of 50% complete. Connection of underground drive to ventilation shaft expected in the third quarter.



Process Plant

The various phases of the process plant construction, along with respective percentages complete are presented in the table below.

June 18 July 15
Total Project 85% 87%
Process Plant
Engineering 99% 99%
Procurement 98% 99%

Structural steel fabrication 95% 100%
Structural, mechanical, piping & electrical installation 55% 70%
Power house 97% 100%
Ventilation upgrade 50% 50%
Tailings impoundment facility 35% 40%

Process plant construction is progressing as planned. Significant milestones achieved since the last development update include:

  • The primary crusher area's structural steel, platework and associated equipment installation is approximately 95% complete. Electrical and instrumentation installations are approaching completion. Commissioning of the primary crusher is scheduled to occur in July.



  • The reagent handling area's structural steel, platework and associated equipment installation is approximately 95% complete. Electrical and instrumentation installations are progressing.



  • All of the structural steel and platework is currently on site with approximately 85% erected to date.



  • Mechanical installations and structural steel erection in the grinding building are progressing well with this area now 75% complete.



  • Significant progress has been made in erecting the conveyor systems. Conveyor belts are on site and installation will proceed during July prior to the start of commissioning.



  • The primary screen, the scrubber, and a number of tanks have been installed in the Scrubbing & Screening building. Installation of pipe and electrical equipment has started.



  • Civil construction of the gold room is complete and this area has been turned over to the mechanical contractor. Erection of tanks and other mechanical installations in the gold room area are progressing. Commissioning of this area is scheduled for late August.



Infrastructure

Other infrastructure construction is progressing as planned. Significant milestones achieved since the last development update include:

  • The power house is now 100% complete and commissioned. Connection to the grid is expected by the end of July. The Company is currently running two of the four generators and electrical reticulation across the project site is substantially complete.



  • Construction of tailings dam has been advanced. The total construction is now 40% complete with the spillway wall formwork and rebar progressing as planned. The cut-off excavation is now finalized, the horizontal filter has been installed and the dam foundation is in place. The tailings dam is expected to be ready in conjunction with the start of mill commissioning.



  • Widening of the ventilation shaft is also progressing on schedule. A three-fold increase in air volume to the underground operations is expected by the end of the third quarter with an additional two-fold increase in air volume occurring in the fourth quarter.
