SANDFIRE RESOURCES LIMITED Sandfire Resources NL (ASX: SFR) are exploring 100% owned Enterprise Metals' Doolgunna Project tenements, and will earn a 75% interest upon discovery of a minimum of 50,000 tonnes contained copper (or equivalent).
Sandfire has continued with intensive drilling programs at Doolgunna, with exploration focused along the highly prospective VMS corridor southwest of the Monty deposit. Since commencement in October 2016, Sandfire has completed 1,481 drill holes for 125,672m in Enterprise tenements.
Work has included:
- RC drilling within the Vulcan and Vulcan West Prospect areas to test geochemical anomalism identified in AC drilling
- Continuation of a major 600-hole aircore (AC) drilling program to test 50 strike km of the interpreted favourable volcano-sedimentary sequence which hosts the DeGrussa and Monty copper-gold deposits
- Infill AC drilling at the Homestead prospect over lithogeochemical anomalies identified in first pass drilling
- Q3 drilling included reverse circulation (RC) drill holes and 765 AC drill holes for combined 63,537m
- Further diamond and RC drilling is planned for next quarter
- A project wide airborne EM survey commenced in August
- A ground geophysical (MLEM) survey is planned to cover prospective Karalundi Formation stratigraphy
Commenting on Sandfire's work, Enterprise's Managing Director Dermot Ryan said:
"We are very pleased that Sandfire is continuing to undertake a thorough and systematic exploration program in Enterprise's Doolgunna Project area. We are looking forward to the results of Sandfire's extensive geophysical surveys and drilling programs."

OVERVIEW
Enterprise Metals Limited (ASX: ENT, "Enterprise" or "the Company") is pleased to announce that Sandfire Resources NL, its exploration farm-in joint venture partner at Doolgunna in Western Australia, has continued its aggressive exploration activity across multiple prospects within the joint venture tenements.
To date, Sandfire has completed a total of 1,481 drill holes for a combined 125,672m including;
Air-core drilling - 1,465 holes for 119,556m
Reverse circulation drilling - 10 holes for 3,745m
Diamond drilling - 6 holes for 2,743m
Sandfire has also completed downhole electromagnetic (DHEM) surveys, commenced an airborne electromagnetic survey, and plans to commence ground geophysical surveys (MLEM) over the Doolgunna Project.

Since commencement of the farm in joint venture, Sandfire has completed 1,465 air core drill holes for a total 119,556m across the Vulcan, White Well, Ruby Well and Mount Leake Prospects (Figures 2 and 3).
The drilling has provided significantly improved stratigraphic control, with a focus on tracing the intersections of magnetite and hematite-rich exhalative sediment horizons with disseminated pyrite that have been encountered particularly within the Vulcan area.
At White Well, anomalous gold values (1.53 ppm Au) and copper values (4,000 ppm Cu) have been reported. Drilling at the Vulcan prospect reported copper values up to 1,460 ppm Cu. Significant results are included in Table 1 below.
RC drilling has been undertaken to follow-up some of the anomalous results (refer RC Drilling section page 5 of this report).
