CORRECTION FROM SOURCE-Mawson West Limited: Kapulo Project Drilling Update

PERTH, AUSTRALIA--(Marketwired - Nov 21, 2013) - Mawson West Ltd. (TSX:MWE) ("Mawson West" or "the Company") issued a press release on 19 November 2013 that contained an error in Appendix B - Table 5 entitled "2013 Safari South drill results to end of October 2013" contained in the press release. This error was not material. A corrected press release in its entirety is included below.

Highlights:

• Kapulo resource definition drilling 85 per cent complete;
• Shaba results confirm high-grade copper to beyond current pit design limits, including 25 metres @ 6.79% Cu, 30 metres @ 6.37% Cu;
• Safari North results indicate potential for a high-grade open pit, including 19 metres @ 6.39% Cu, 22 metres @ 5.82% Cu;
• Drilling at Safari South confirms continuity of mineralization over 350 metres strike length.

Mawson West Chief Executive Bruce McFadzean said:

"Further de-risking and expanding the Kapulo resources have been a major priority for the Mawson West exploration team this year and we can now see the results of that work coming to fruition. An extended life at Kapulo will underwrite the future of Mawson West when the mine is commissioned in 2014."

Mawson West Ltd. (TSX:MWE) ("Mawson West" or "the Company") is pleased to provide an update on the results of ongoing drilling at the Company's Kapulo copper project in the Democratic Republic of Congo ("DRC").

Overview

Kapulo comprises three outcropping copper deposits, Shaba, Safari North and Safari South (Figure 1). Together, the three deposits comprise total Indicated Resources of 5.95Mt @ 3.5% Cu and 9ppm Ag, and Inferred Resources of 2.42Mt @ 2.2% Cu and 6ppm Ag(1) (Table 1, Appendix A). Mineral Reserves have been estimated only for the Shaba deposit: 3.6Mt @ 3.6% Cu and 8.3ppm Ag (Table 2, Appendix A). The Shaba Mineral Reserve formed the basis for the decision to proceed with development of Kapulo copper project.

Drilling programs have been carried out at Shaba, Safari North and Safari South deposits since February 2013, with the effort stepped up from one rig to three rigs in May 2013. The objectives of the drilling campaign have been to upgrade the confidence categories of all resources, enable estimates of Mineral Reserves for Safari North and South deposits and obtain core samples for additional metallurgical test work. To the end of October, the 2013 program totalled 9,735 metres in 149 RC holes and 6,500 metres in 45 diamond core holes (including 2.034 metres in RC pre-collars). A further 353 metres of RC and 110 metres of core has been drilled in eight sterilisation holes.

At the end of October remaining planned drilling totalled approximately 1,900 metres of RC and 1,100 metres of core. It is anticipated that drilling will be complete by the end of November 2013, with re-estimation of resources to follow immediately. The updated resource models will form the basis for new Mineral Reserve estimates, mining schedules and financial modelling to be undertaken in Q1 2014.

Drill results available at mid-September for Shaba and Safari North deposits, along with those available at end of October for Safari South deposit, are discussed below.

Shaba Deposit

Figure 2 shows a long-projection of Shaba deposit, looking west. The figure represents horizontal width of mineralisation above 1% Cu cut-off multiplied by Cu grade, i.e. Cu grade x thickness metal accumulation. The figure is diagrammatic, based on the drill results available at mid-September 2013 and does not represent the model of Mineral Resources. The southerly plunge of the mineralisation is clearly represented. The open pit profile on the image represents the pit design within which the June 2011 Mineral Reserve was delineated.

Drill intercepts shown on Figure 2 represent holes for which assay results were available at mid-September 2013, with those returning greater than 10 metres estimated true width x Cu% labelled. Table 3 (Appendix B) presents the entire table of results along with drill hole location details.

The results to date confirm high-grade mineralisation proximal to the current pit design limits. The Company anticipates that re-evaluation of the optimum pit limits, in conjunction with upgrading of Inferred Resources to Measured and Indicated categories by virtue of closer drill spacing, may lead to an increase in the Shaba Mineral Reserve.

Safari North Deposit

Figure 3 shows a long-projection of Safari North deposit, looking west. The colour scheme is the same as that for Figure 2. The open pit profile on the image represents the possible limits of an economic pit, based on pit optimisations of Safari North excluding 2013 drill results.

Drill intercepts shown on Figure 3 represent holes for which assay results were available at mid-September, with those returning greater than 10 metres estimated true width x Cu% labelled. Table 4 (Appendix B) presents the entire table of results along with drill hole location details.

Pre-2013 drilling of Safari North was sufficient to define only about fifty per cent of the deposit as Indicated Resources, precluding a realistic estimate of Mineral Reserves. The Company expects that 2013 infill drilling will result in delineation of the bulk of the deposit as Measured and Indicated Mineral Resources, permitting estimation of Mineral Reserves.

Safari South Deposit

At Safari South, limited drilling prior to 2013 was sufficient only to delineate an Inferred Mineral Resource.

Drilling during 2013 has confirmed that mineralisation extends over at least 350 metres strike length, with potentially economic copper grades extending to 40-50 metres below surface. The Company expects that data from the 2013 drill campaign will be sufficient to define Measured and Indicated Mineral Resources and potentially define Mineral Reserves.

Drill results available up to end of October are listed in Table 5 (Appendix B).
