Drill hole GRRC8 was drilled in to the breccia ‘pipe' from the east towards Adit 1 and intersected the highest silver values encountered to-date: 20m @ 292g/t silver, 1.74% zinc and 0.25% copper or 502g/t silver equivalent.
Lower grade silver mineralisation was encountered above and below this intercept.
Hole GRRC9 was drilled beneath a breccia ‘pipe' outcrop approximately 150m north east of Adit 1 and encountered a best intercept of 4m at 120g/t silver, 2.47% zinc and 0.25% copper, with lower grades of silver mineralisation above and below the intercept.
Hole GGRC10 was drilled at a steeper angle beneath GRRC9 but terminated as it entered the breccia ‘pipe'.
Hole GRRC11 was drilled midway between the Adit 1 area and the intercept in GRRC9. There was no surface expression of the breccia ‘pipe' above where the drill hole penetrated. Between 70 and 80m downhole, a 10m intercept of 115g/t silver, 0.14g/t gold, 1.42% zinc, 0.33% lead and 0.16% copper was encountered. At 112m downhole, an intercept of 6m at 109g/t silver, 1.36g/t gold, 2.18% zinc and 0.27% copper was located. The hole terminated in an 8m interval of 76g/t silver and 0.17% copper. These intercepts have extended the area over which the silver mineralisation occurs and the intercept recorded in GRRC8 confirms the tenor of values obtained in the historical sampling carried out in Adit No. 1 and Adit No. 2.

Notes:
- The silver equivalent grades are tabulated, as silver is the metal of major economic significance encountered in the drill intercepts. The following metal prices were used in the calculation. Silver AUD$15/oz, copper AUD$4.66/lb, zinc AUD$2.00/lb, lead AUD$0.66/lb, gold AUD$800/oz. Silver equivalent values will change over time as any one or more metal prices change.
- True widths of the intervals quoted are not listed, as the orientation of the mineralised zone is uncertain.
| DRILLING AND SAMPLING DETAILS All samples were collected as percussion chips/dust from the reverse circulation drilling rig. Assay samples were collected over 2m intervals through the mineralised zones and over 4m intervals through the visually non-mineralised zones. As part of the Company's quality control programme, a duplicate sample is collected about every 20 samples and submitted under a different sample number providing a check on repeatability. Assaying is carried out by ALS Chemex in Brisbane using the ICP technique for silver, copper, lead, zinc, arsenic, antimony, bismuth and molybdenum. Gold is assayed by the ICPMS technique. |

"TALLY HO PROJECT PURCHASED - VENDORS OPT FOR MACMIN SHARES
Encouraged by initial drilling results, the Company has moved to exercise its option over the Tally Ho project near Mackay. The Company announced that it had secured an option to purchase the project on 9th May 2006.
The vendors had the right to receive cash or equivalent shares for the $300,000 purchase consideration. The Company is pleased to advise that the vendors opted to receive shares and 937,500 fully paid ordinary shares have been issued today to complete the transaction.
- The Tally Ho silver project is located approximately 50 km south west of Mackay in Central Coastal Queensland and consists of 2 granted Mining Leases (ML's 4770 and 4727), a surrounding Mineral Development Licence Application (MDL272) and a 24 sub-block (78sq.km) Exploration Permit for Minerals (EPM15168)
- Macmin's initial test drilling of the Tally Ho workings has given, as recently reported, a best downhole intercept of 20m at 292g/t silver, 1.74% zinc and 0.25% copper or 502g/t silver equivalent.
In addition, Macmin has applied for 2 further exploration areas for silver in the Mackay region. The Pisgah tenement comprising 23 sub-blocks (69km²) covers the northern part of the Tally Ho Intrusive Complex (THIC). In light of our assessment of the initial findings at Tally Ho, we believe the THIC has significant potential to host Intrusion Related Mineralising Systems (silver, gold, zinc, lead, copper).
A second area comprising 86 sub-blocks (258km²) - Mt Scott - is situated 75km south of Mackay and covers the Mt Scott Granite. This area has been the subject of previous exploration with stream geochemistry and prospecting, which located a number of prospects. At the Mt Scott South prospect, a 1.2km² sulphide system containing up to 5% pyrite occurs in a series of quartz stringer and quartz vein zones approximately 100m in aggregate width and a strike length of 500m. These veins occur near a breccia body (100m long by 80m wide) with porphrytic granite clasts within a sulphide matrix.
Once these tenements are granted, an intensive programme of exploration will be undertaken to evaluate their potential to host Tally Ho style mineralisation."
"MACMIN TO RECOMMENCE DRILLING AT TALLY HO SILVER PROJECT
The success of the first ever drilling programme to test for silver mineralisation at the Tally Ho Silver Project near Mackay in Central Queensland has encouraged the Company to embark on a further drilling programme prior to the onset of the ‘wet' season. The programme consists of 1,000 metres of reverse circulation (RC) drilling and 1,000 metres of diamond drilling and commences on or about October 25th.
During September, the Company acquired a 100% interest in the Tally Ho Silver Project tenements. In addition, two further exploration areas for silver were applied for in the Mackay region. In light of our assessment of the initial findings at Tally Ho, we believe this region displays significant potential to host Intrusion Related Mineralising Systems (silver, gold, zinc, lead, copper).
The final results from the 18 hole RC drilling programme (2,313m) carried out in August have now been received and a table of all significant results is presented. Results from holes GRRC1 to GRRC11 have previously been reported on. Drill hole GRRC8 encountered the best intercept of 20m (downhole) @ 292g/t silver, 1.74% zinc and 0.25% copper or 503g/t silver equivalent.
The drilling has demonstrated that silver and base metal mineralisation is hosted in a ‘breccia pipe' unit within the Tally Ho Intrusive Complex (THIC). Although the ‘breccia' occurs in outcrop, the initial drilling has shown that it is more extensive at depth.
Diamond drilling will be undertaken to test the depth extent of silver mineralisation, as several holes terminated in silver mineralisation in the initial RC programme. In addition, drill testing (RC) will also be aimed at extending the strike extent of the mineralised system.
The tenor of the silver values coupled with the consistent zinc and copper credits shows the signs of a very promising project."

"SINIVIT MINE DEVELOPMENT
The development of the Sinivit Gold Project experienced further delays due to unseasonable weather. In late August, over a two day period, 350mm (14 inches) of rain fell, followed by several days when 50mm (2 inches) was recorded each day. This weather set the schedule back about three weeks. On the 13th September a further 320mm (12.8 inches) of rain fell with 150mm (6 inches) on the 14th September. This latter rainfall has not resulted in any substantial delays, due to substantial upgrading of all site roads over the past few weeks. Total rainfall for the past year has been more than 200% of average annual rainfall and has been the main reason for delay in project completion.
Other stalls in development have been caused by late delivery of equipment due to shipping delays, a consequence of the general pressure on suppliers of mining equipment. For example, the screening plant from Ireland was off-loaded in the Solomon Islands (it is now on site), the scheduled shipping of the crushing plant to site has now been twice delayed and, in another instance, our cargo was left at the wharf in Brisbane, Australia.
Construction capital expenditure is 90% expended and total capital cost to date is approximately C$6.5 million. Delays and increases in costs will add approximately C$1 million to the original capital estimate.
With all equipment at Sinivit by mid October, with the mining contractor now fully operational and all on-site roads fully operational, we do not expect further significant delays to the revised schedule below.
The development schedule at present is as follows:
- Mine infrastructure, camp etc - essentially complete.
- Access road - complete
- Mine roads, including haul roads - essentially complete
- Maintenance facility - complete
- Screening plant, gold recovery circuit, laboratory - all on site with erection completed by end of October 2006.
- Contractor - all equipment on site and now assisting in completion of site works, roads, vats etc.
- Crushing plant expected to be on site by mid October 2006, in place and commissioning to occur during November 2006.
- Pre-stripping of the mine will commence in late September 2006 and waste will initially be used in vat walls
- The first two vats should be completed and lined by the end of November
- Mining and crushing of ore will commence in December 2006 with gold production in January 2006.
Most of NGG's projects already have significant defined mineralisation in drill hole and/or trench. For details refer to project descriptions at www.newguineagold.ca . The Company's main objective is to increase its resource base as rapidly as possible. At present, three diamond core rigs are being used for resource definition at the Imwauna (100% NGG) and Mt Penck (60% NGG) Projects. Imwauna is within the Normanby Property. NI 43-101 compliant resource estimates are targeted for both projects for completion in late 2006 or early 2007.
Independent Qualified Person, Ralph Stagg, visited the Normanby, Sehulea and Mt Penck properties in preparation for compilation of Independent Technical reports on those properties.
NGG has acquired two further drills which will commence operating at its Sinivit property in early October, 2006, with the objective of increasing the present defined resources.
Excellent drill results are being received from both Imwauna and Mt Penck.
Imwauna (Normanby Property - 100% NGG)
Resource definition drilling has continued using a single diamond core drill rig. Subject to available finance it is intended to acquire a further drill rig for the project later this year or early 2007. Excellent drill assays have been received since the last update and were released in a Press Release dated 13th September 2006. In particular two further holes were drilled into the high grade zone noted in the last update. Previous intersections into this zone gave best results of 6m at 68g/t gold including 3m at 106g/t gold and 6.45m at 20.9g/t gold (see Press Release dated 26th July 2006) In the latest Press release the highest gold value so far intersected in core at Imwauna, 438g/t gold, was noted with the best intersections summarized below. All results are available in the Press Release of 13th September 2006.

The Imwauna Vein system has been defined at surface over a length of 1.2 kms by excavator trenching (see web site www.newguineagold.ca for excavator trench results). Approximately 110 drill holes have now been completed over approximately 850m of the 1.2 km system. The vein system with significant gold grades is now known to extend over a vertical interval of at least 200m. In the southern end of the system the highest grades and greatest widths are occurring at depths of greater than 50m. An additional drill is required to extend our knowledge of the system to greater depths.The individual veins within the Imwauna Vein System are not planar or linear over long distances. They vary in dip from as low as 50 degrees west to 65 degrees east. In addition veins may bifurcate into two or more veins, substantially vary in thickness and attitude over intervals of less than five metres thus making estimation of true thickness of any intersection uncertain. All data is being compiled into a Surpac model to more accurately assess continuity, attitude and thickness of individual veins.
Mt Penck Project (60% NGG)
Drilling has proceeded rapidly at the Kavola East Prospect at Mt Penck with 24 holes now completed and results available for 19 holes (including one historic hole).
The drilling is defining widespread and multiple zones of lower grade disseminated type gold mineralisation with mineralisation commencing at surface and traced to a depth of approximately 130m at present.
Two drill rigs are operating, but in October one rig will be mobilised to drill at the Simuku and Mt Nakru properties and the remaining rig will continue drilling at Mt Penck for the remainder of 2006. A total of 18 drill holes since mid 2005 have now been reported and all drill holes intersected several zones of mineralisation at greater than 0.5g/t (see the better intervals shown below, and refer to Press Release dated 6th September 2006 for all results).
There appear to be both vertical and horizontal controls to the mineralisation and the true thickness of any intersection is not known.

Mt Nakru (NGG 75%) and Simuku Properties (NGG 90%)NGG's strategy is to develop both the Simuku (90%) and Mt Nakru (75% NGG) copper/gold/molybdenum prospects through to pre-feasibility within two years. However, since these are base metals properties, NGG believes that the value of these properties is not reflected in the Company's share price and, in conjunction with its advisors, is examining a number of options to create value and fund the required exploration.
Drilling Schedule for Remainder of 2006
An RC and diamond core rig has been purchased for the Sinivit Project, and both should be in operation by early October, also with the objective of defining resources.
The drilling schedule for later in 2006, commencing in late October, anticipates several short drill holes to test the molybdenum potential of the surface molybdenum mineralisation (73m @ 0.17% molybdenum in trench) at the Simuku porphyry copper/gold/molybdenum Project and possibly 5 or 6 holes to test the recently discovered gold in trench (35m at 7.2g/t gold) at the Mt Nakru porphyry copper/gold Project. NGG continues to examine options to enhance the value of these projects for shareholders.
NGG also anticipates drilling several holes at the Weioko Prospect (Sehulea Property NGG 100%) towards the end of the year to ensure compliance with work commitments, using the drill rig presently at Imwauna.
CORPORATE
NGG has agreed to an extension to June 30, 2007 for Vangold Resources to spend a further C$1.26M and issue 200,000 common shares to earn a further 25% in the Feni Islands Project (EL 1021). Vangold presently owns 50% of the project. The Feni Islands lie within the Lihir Corridor, which hosts the world-class porphyry copper-gold deposit at Bougainville and the large gold deposit at Lihir Island (approx. 50 million ounces gold). Fieldwork has resumed at Feni and will target the Dome Prospect which occupies approximately one-third of the now extinct central crater on Ambitle Island, the larger of two islands that comprise the Feni Islands.NGG has accepted an offer of Kina 7 million (about C$3 million) standby credit facility from Bank of South Pacific, the leading Papua New Guinea based bank, with assets totalling Kina 2.95 billion (C$ 1.3 billion). The line of credit is regarded as "insurance" but could provide required working capital for the Company prior to receipt of cash flow. Final documentation is in progress.
NGG has approximately C$2 million in available cash and would prefer to raise a minimum of C$3 million in further capital to fund the following requirements:
- to provide mine working capital for the Sinivit Gold Mine for the 3 to 4 month period of plant commissioning, filling of vats etc, before receipts from gold sales are received which is expected by January 2007. Due to the processing method there is a 3 month period from when mining commences and when the gold is refined and proceeds received.
- to allow the present exploration program to continue without interruption, and to be expanded by adding a further two drill rigs, until it can be financed from mine cash flow. By October 2006 we expect to have four diamond core drill rigs and one RC drill rig working on NGG's three key gold projects and we would like to purchase two further drill rigs which would then be operational early in 2007.
