Mandalay Resources announces multiple high-grade drill intercepts on several veins and begins infill drilling at its Cerro Bayo Silver-Gold Mine, Chile
TORONTO, July 9, 2014 /CNW/ - Mandalay Resources Corp. ("Mandalay" or the "Company") (TSX: MND) is pleased to announce encouraging results of its continuing wide-spaced core drilling program from underground and surface platforms to probe for vein extensions and has recognized two new veins under Laguna Verde (click here for Figure 1 - Laguna Verde Drill Plan View).
Highlights of the results during the first half of 2014 include:
- Coyita vein (Figure 2 and Table 1) — Thirteen new intercepts have defined the extension of the Coyita vein, establishing a strongly mineralized zone approximately 500 m along strike and at least 200 m down dip on the vein. The best intercepts occur between the Laguna Verde fault and the Peninsula fault, although the vein continues to the northwest of the Laguna Verde fault, where the existing reserves are located, and to the southeast of the Peninsula fault.
- Yasna vein (Figure 3 and Table 2) — New drilling has not extended the previously disclosed 200 m by 50 m mineralized zone in Yasna under Laguna Verde, half of which lies in the hanging wall of the Laguna Verde fault. However, one drill hole between the two previously announced intercepts has confirmed the zone. The previously announced limit of reserves in the Yasna vein under the northwest lake shore has been extended to the southeast for approximately 75 m by underground development sampling on two levels which are still open, and by one new drill hole.
- Kasia vein (Figure 4 and Table 3) — Kasia is a new vein that has been recognized in eight intercepts. The mineralized zone extends at least 300 m along strike, straddling the Laguna Verde fault, with the best intercepts located in the hanging wall of the fault. The top of the zone is well defined, whereas the bottom is open, with a dip dimension of at least 75 m.
- Irene vein (Figure 5 and Table 4) — Five intercepts in the newly recognized Irene vein include one very high-grade intercept in the hanging wall of the Laguna Verde fault and four low-grade intercepts in the footwall.
Brad Mills, CEO of Mandalay, commented, "Mandalay's 2014 drilling to follow up on the initial high-grade intercepts on Yasna and Fabiola veins under Laguna Verde, reported on January 15, 2014, has been rewarded with excellent results, particularly on the Coyita vein. There, we have delineated a continuously mineralized zone 1 - 3 m wide for more than 500 m along strike and as much as 200 m down dip. There are some extraordinary intercepts reported in this zone, notably 1.47 m of 32.9 g/t Au and 1,821 g/t Ag in hole DLV14-025; 3.61 m of 8.87 g/t Au and 282 g/t Ag in hole DLV14-027; and 2.55 m of 4.47 g/t Au and 442 g/t Ag in hole DLV14-009."
Mr. Mills continued, "While new geologic interpretations have closed off extensions of the Fabiola vein under Laguna Verde, these interpretations plus new drill intercepts have confirmed the previously reported mineralized zone in Yasna and have defined two new mineralized veins, Kasia and Irene."
"All our drilling for the remainder of the year will be for the purpose of infilling Coyita, Yasna, and Kasia veins in the footwall of the Peninsula fault; we expect a significant addition to resources and reserves in our year-end Technical Report. After this episode of infill drilling, we can return in 2015 to wide-spaced drilling in the hangingwall of the Peninsula Fault and elsewhere under Laguna Verde to continue tracing the veins further along strike and probing for new veins."
Cerro Bayo drilling and assaying
A total of 9,327 m of diamond core in 34 holes were drilled at Cerro Bayo in the first half of 2014. Of these, 6,617 m in 22 holes were drilled under Laguna Verde from underground stations in the Dagny and Yasna mines as well as from surface platforms around the lake. All holes were directionally surveyed. Core was logged and sampled by Mandalay geologists. Core samples, including blanks, standards, and duplicates, were assayed on-site at the Compañia Minera Cerro Bayo laboratory. The Cerro Bayo laboratory, which was audited in 2011 by SGS Lakefield Research Ltd., routinely sends check samples to ALS Laboratory (an ISO 9001:2008 and ISO/IEC 17025:2005 certified laboratory) in La Serena, Chile, following QA/QC practices established by Mandalay. See the Company's previously filed technical report entitled "Technical Report on the Cerro Bayo Project, Region XI (Aisen), Chile", dated March 28, 2014, for a full description of the drilling, logging, assaying, and estimation processes, including data verification measures.
Locations of the veins discussed in this press release appear in Figure 1, along with the locations and orientations of the drill holes.

Drilling results outside the Laguna Verde area
Approximately 2,700 m of core drilling was completed in 12 holes during the first half of 2014 on targets outside the Laguna Verde area, including the Cristal vein, the Esperanza system, and the Cerro Amarillo zone. This "new target testing" drilling has returned inconclusive results which are still undergoing evaluation.
