My blog is all about the famous outback Australian National Heritage Listed City named Broken Hill, located in the state of New South Wales. I first visited #BrokenHill in 2002 and have returned many times since then. ilovebrokenhill.com will help you discover what's great about this historic mining city, where in the mid 1880's the line of lode, a rich ore body of silver, lead and zinc was found. You will find stories about anything related to Broken Hill.

Silver City Minerals and Impact Minerals joint venture drilling commencing Spring 2015

Mining Industry
A bit of mining news!
Drilling is to commence next week at the 'High Grade Copper-Nickel-Platinum Project' in Broken Hill - ASX Announcement 26 August 2015 (number 418/260815)

Here is the announcement, sourced from the Silver City Minerals website - main points -

A drill program of up to 1,500 m of diamond drilling is due to start by the end of next week at Impact Minerals Limited (ASX:IPT) high grade copper-nickel-platinum (PGM) joint venture project near Broken Hill in New South Wales.

The drill program will test seven targets (T1 to T7) at the Red Hill Prospect which covers about one square kilometre, where Impact has discovered a 25 to 30 metre thick near-surface layer of copper-nickel-PGM mineralisation. The mineralisation mostly occurs in two zones of high grade drill intercepts called the Upper and Lower Zones (Figures 1 and 2-see website) which returned:

Upper Zone: 9.5 m at 4.7 g/t 3PGM, 1.5% copper and 0.8% nickel including
5.1 m at 11 g/t 7PGM, 1.9% copper and 0.9% nickel (RHD001) and
5.2 m at 7.9 g/t 7PGM, 1.1% copper and 1.6% nickel (RHD006)
Lower Zone: 9.9 m at 6.7 g/t 3PGM, 1.4% copper and 0.3% nickel including
4.2 m at 11.8 g/t 7PGM, 2.6% copper and 0.5% nickel (RHD001) and
13.8 m at 6.6 g/t 7PGM, 1.1% copper and 0.3% nickel (RHD006).

Note 3PGM = Platinum-palladium-gold and 7PGM = 3PGM + osmium, iridium, rhodium, ruthenium where assayed (full details in Table 1-see website for table).

These results are some of the highest grades of PGM ever reported in Australia.

The two zones of mineralisation are interpreted to dip at a shallow angle to the south and may be increasing in width and grade with depth (Figure 1-see website). In addition the mineralisation is in part coincident with an Induced Polarisation (IP) chargeability anomaly identified in a ground geophysical survey (Figures 1 and 2-see website). This is Target T1 and follow up drilling is planned to test the mineralisation at depth and along trend (Figure 2)-see website.

The other five drill targets consist of one ground (T2) and one down hole (T3) electromagnetic anomaly, a rock chip geochemical anomaly (T4), two induced polarisation (IP) anomalies (T5 and T7) and an airborne magnetic anomaly (T6) (see announcement dated 1st April 2015).

Further drill targets may also be identified from the results of a recently completed ground gravity survey over the area. Interpretation of this data is in progress.

The drill rig is scheduled to mobilise to site early next week.


Stay tuned for further developments.
