Mandalay Resources continues infill and extensional drilling on N- and Cuffley lodes at its Costerfield gold-antimony mine, Victoria, Australia

TORONTO, July 17, 2014 /CNW/ - Mandalay Resources Corporation ("Mandalay" or the "Company") (TSX: MND) is pleased to announce drill results from its infill and extensional drilling at the Costerfield gold-antimony mine, Victoria, Australia during the first half of 2014. Highlights include:

  • Cuffley lode (Figure 1 and Table 1)New intercepts have infilled a 50 m by 100 m area of previously Inferred Mineral Resource at the southern end of the lode and added a further 50 m strike length of new mineralization. The Cuffley lode is now closed off to the south. New intercepts and mine development have also confirmed previously Inferred Mineral Resource in a trapezoid 100 m along strike at the top, 200 m along strike at the bottom, and 100 m down dip at the northern end of Cuffley.

  • N-lode (Figure 2 and Table 2)— New intercepts and vein development have infilled a 100 m by 50 m area of previously Inferred Mineral Resource along the bottom of N-lode.

In addition, initial drill testing of high priority new targets beneath and along the main lines of lode in the district (Figure 3 and Table 3), including from south to north the Margarets, Augusta East, Tin Pot Gully, and Brunswick targets, has not yet generated evidence of a new orebody.

Brad Mills, CEO of Mandalay, commented, "The infill and extensional drilling results so far this year give us confidence in being able to once again increase our Reserves and Resources in the year-end 2014 estimations. In particular, drilling continues to generate some extremely high-grade intercepts on the Cuffley lode, for example AD093 (6.7 m true width at 31.4 g/t Au and 25.5% Sb), AD092A (0.63 m true width at 7.0 g/t Au and 43.9% Sb), AD076 (2.19 m true width at 19.7 g/t Au and 7.3% Sb), and AD074 (0.36 m true width at 44.5 g/t Au and 62.7% Sb).  We plan to complete infilling the Cuffley lode extensions by the end of the year."

Mr. Mills continued, "We also drilled several wide step-out holes to test new targets along the Costerfield district strike. While no significant new discoveries were made in the brownfields drilling, previous high-grade intercepts at Margarets to the south and the Bombay-Minerva-Costerfield area to the north remain to be followed up. In addition, there are several targets off the main line-of-lode that have not yet been tested." 

Costerfield drilling, sampling, and assaying

During the first half of 2014, Mandalay drilled 14,462 m in 42 holes. In addition, the Company completed 2,299 m of on-vein operating development and associated sampling of the N- and Cuffley lodes. Drill core was logged and sampled by Costerfield geologists, who also performed mine sampling of the development advances. All samples were sent to Onsite Labs in Bendigo, Victoria, Australia, for sample preparation and assay. Site geological and metallurgical personnel have implemented a QA/QC process that includes the regular submission of standard reference materials and blanks with drill and face samples submitted for assay. Standard reference materials have been certified by Geostats Pty Ltd. (see March 28, 2014, Technical Report entitled "Costerfield Operation, Victoria, Australia NI 43-101 Report", available on SEDAR (www.sedar.com), which contains a complete description of drilling, sampling, and assaying procedures.)
