RAMBLER METALS AND MINING PRODUCES OVER 5,000 OUNCES OF GOLD AND INTERSECTS 278 G/T GOLD OVER 2.60 M IN EXPLORATION DRILLING
Rambler Metals and Mining PLC has provided a project update for the 100-per-cent-owned Ming copper-gold mine.
Highlights
Gold
- Fiscal second quarter gold production of 4,022 ounces (as at Jan. 31, 2012);
- Total of over 5,000 ounces of gold has been poured to date at the Ming mine;
- Exploration diamond drilling in the 1806 zone returned new visible gold
intersection of 2.6 metres (core length) of 8.1 ounces/ton gold (278 grams per tonne
gold uncut)
.
Copper
- Continued development of the high-grade copper 1807 zone with live ore
commissioning for the concentrator scheduled for the fiscal third quarter of 2012;
- Development face sampling in the 1807 zone returned grades of 4.48 per cent
copper, 0.83 g/t gold and 8.88 g/t silver over 3.40 metres.
Peter Mercer, vice-president corporate development, commented:
"We are pleased with the continuous improvements at the Ming mine, both underground and at the milling facility. We are also encouraged by the discovery of new visible gold near our current stoping levels; however, our focus remains on optimizing our processes to ensure that we maximize the potential of the underexplored areas of the Ming mine.
"We look to continue to develop and increase our revenue stream to ensure that the company continues to grow over the near term."
Gold production
The operations team continues to optimize gold production from the Ming mine. The average daily throughput for January was 600 million tonnes per day with the highest one day throughput being 695 million tpd. This production rate confirms the projected tonnage rate determined by the company's feasibility study, noting that the reported recovery of gold through the plant is nearing 92 per cent.
Since the start of gold production in November, 2011, Rambler has poured 3,563 ounces for the quarter ending Jan. 31, 2012. The higher than projected refined ounces is a result of slightly higher head grades than the estimated 1806 reserve grade. The table attached summarizes the company's gold production to date including preliminary results for the beginning of fiscal third quarter for 2012.

The mills performance during the early processing of the 1806 has exceeded expectations and the exploration diamond drilling program has been particularly exciting, including the discovery of new visible gold intersections down plunge of the 1806 zone. In the past, the company has reported visible gold deeper in the mine, in and around the historic 1,700-foot level (see press release dated May 10, 2011), but these types of grades have never been reported this high in elevation or adjacent to the company's current stoping blocks on the 100 level.
The diamond drilling results in the table attached indicate the discovery potential for additional high-grade gold mineralization at the Ming mine. While the drilling was originally part of an exploration program, having the intersection located just 30 metres from existing underground infrastructure the company plans to develop across the zone to better understand the controlling structures hosting the gold mineralization. This development can then be utilized as ore access for future production.
Down plunge of the discovery has not been adequately tested for several hundred metres and will be incorporated into the company's exploration program.

Copper production
Development into the high-grade copper 1807 zone is continuing and the company anticipates commencing copper production during the fiscal third quarter of 2012. Geological mapping and sampling of the 1807 zone development have given the company an opportunity to better understand the geometry and structural controls which define the shape of the ore zones. To date, the results are encouraging in that they are consistent with previous interpretation and grades.
The intersection of high-grade massive sulphides while developing the 1600-level bypass ramp, is an additional encouragement to the company. Development chip samples from this zone returned 3.73 per cent Cu, 2.11 g/t Au, 30.78 g/t Ag and 0.78 per cent Zn over a thickness of 1.6 metres. This new zone will be drill tested both up plunge and down plunge to determine the extent of the mineralization. The table attached summarizes a few of the composited development samples collected to date. This is a continuing program for which the company will provide further updates over the course of the year.
