Exploration update - Ned's Creek JV
HIGHLIGHTS
- RC drill program managed by Lodestar completed at Ned's Creek Joint Venture
- Drilling results will contribute towards a Mineral Resource estimate over a zone of shallow supergene gold mineralisation to support a potential future open pit mine
- 14 holes completed over a 600m zone targeting the Contessa granite contact as the potential source of supergene mineralisation at Contessa intersected an extensive hydrothermal system which remains open.
Lodestar Minerals Limited ("Lodestar" or "the Company", ASX:LSR) advises that the RC drilling program at the Contessa gold prospect located on the Ned's Creek Joint Venture (Vango Mining (ASX:VAN) earing 51%) is completed and all samples have been dispatched to the laboratory for assay.
The program comprised 29 holes in total for 3715m (see Table 1) and consisted of two phases.
- a series of 12 vertical RC holes, drilled to a set depth of 90m over an area of 120m by 140m, to verify significant supergene gold intersected in previous aircore drilling and support a maiden resource estimate for the supergene hosted mineralisation;
- 14 holes targeting the Contessa granite contact as a potential source of the widespread supergene and nugget-related gold discovered in the Contessa area; and
- 3 additional RC holes were completed on the contact zone 1500m southwest of Contessa, at the Central Park prospect (Figure 1).
Previous aircore drilling at Contessa intersected extensive supergene gold mineralisation1 prior to RC drilling programs that targeted deeper primary mineralisation. Significant intercepts from earlier aircore drilling include:
- 15m at 3.1g/t Au from 40m in LNR546
- 21m at 3.01g/t Au from 40m in LNR656
- 20m at 1.61g/t Au from 48m in LNR796
- 12m at 1.3g/t Au from 48m in LNR800
- 8m at 3.35g/t Au from 48m in LNR810
- 16m at 2.16g/t Au from 84m in VCTRC0003, including 4m at 9.63g/t Au.
Results from the recently completed program will support a maiden resource estimate for a potential open pit operation at Contessa.

Exploration drilling also targeted the granite contact at Contessa for the first time, testing a strike distance of over 600m, with holes angled to the southeast at regularly spaced intervals of 100m (see Figure 2).
The key observations of the drilling relate to visual confirmation of an extensive hydrothermal alteration system developed on the granite contact.
- Hydrothermal alteration identified within a granodiorite intrusive extends over a distance of at least 400m.
- The hydrothermal alteration consists of strong silica and/or sericite alteration with associated disseminated pyrite. Accessory molybdenite and fluorite observed within the alteration zone are consistent with the extensive Bi-Mo geochemical anomaly that first identified the Contessa exploration target (see Lodestar's ASX announcement dated 18th December 2012). The alteration is pervasive and interpreted to be associated with the intrusion of a fluid-rich, undeformed late granitic phase.
- Hole LNRC097, the most south westerly hole in the Contessa program, also intersected silica alteration with disseminated pyrite in schistose rocks adjacent to the contact (the contact itself was not intersected).
- Previous aircore drilling completed between the Contessa and Central Park prospects (1500m along strike to the south west) does not extend over the contact intersected in this program.

Lodestar Managing Director, Bill Clayton commented "Although the outcome of the drilling will not be known until assay results are received, the identification of an extensive hydrothermal alteration system associated with the granite contact has confirmed the conceptual model and shown that it is of significant scale. We await results with great anticipation."

About Lodestar
Lodestar Minerals is an active Western Australian gold and base metal explorer.
Lodestar's projects comprise the advanced Nepean Nickel Project JV, the Ned's Creek JV and the 100% owned Camel Hills, Imbin, Jubilee Well, Coolgardie West and Bulong projects.
The Imbin Project is a major strategic land holding in the emerging Earaheedy Province, site of Rumble Resource's recent and potentially world-classZinc-Lead discoveries. The Imbin Project is located on the northern margin of the prospective basin and is the site of significant historic copper intersections in drilling and approximately 20km of strike of the target Yelma-Frere unconformity
Lodestar discovered multiple zones of syenite intrusion-related gold mineralisation at the Ned's Creek Project on the Yilgarn craton margin, 150km west of Imbin. Vango Mining Limited is earning a 51% interest in the Ned's Creek JV by contributing $5M of expenditure over 3 years.
Bulong and Jubilee Well are recent acquisitions in highly endowed gold districts; first-pass drill programs are being planned. Coolgardie West includes underexplored greenstone prospective for gold, nickel and lithium pegmatites.
