Troy Resources NL: Follow-Up Drilling Indicates High Grades at Two Mile Hill Prospect, Sandstone Western Australia-Further Drilling Planned

PERTH, WESTERN AUSTRALIA--(Marketwire - Dec. 9, 2009) -



- Follow-up drilling targeting the high grade Banded Iron Formation (BIF) hosted gold mineralisation intersected significant gold mineralisation on the western margin of the Two Mile Hill tonalite. The BIF is quartz veined and extensively replaced by pyrite with the best intercepts reported being:

-- TRCD825: 8.5m @ 49.59g/t Au from 195.8m downhole;

-- TRCD821: 2m at 9.1g/t gold from 205m downhole; and

-- TRCD827: 4.75m grading 11.16g/t gold from 198.25m downhole.

- In holes drilled to test the BIF along the eastern margin of the tonalite, gold mineralisation was encountered in quartz veins in the tonalite and in quartz veins in the host metabasalts with a peak value of:

-- TRCD820: 4.8m grading 48.26g/t gold from 114.2m downhole.

- The best tonalite hosted vein intercept was:

-- TRCD824A: 1m grading 21.15g/t gold from 301m downhole.

Troy Resources NL ("Troy") (TSX:TRY)(ASX:TRY) today reported the results of a 9 hole (2,812.6m) follow-up drill program at the Two Mile Hill Prospect, located 2.7km northeast of the Sandstone Mill, which reinforce the high grade potential of the Banded Iron Formation hosted style gold mineralisation identified during drilling completed earlier this year (TRCD733: 13.7m at 25.98g/t gold from 240.1m downhole).

Troy CEO Paul Benson said today that although the latest drilling results were highly encouraging, the nature of the mineralisation in the exploration area meant more work was needed.

"These results are from the third phase of drilling at Two Mile Hill and were aimed at better understanding the high grade mineralisation announced in August of this year," Mr Benson said.

"We have again had some extraordinary intersections, including 8.5m @ 49.59g/t gold. The challenge continues to be proving up a target of sufficient size that justifies development.

"With this in mind, the overall results are viewed as sufficiently encouraging for the Board to approve a further 8 hole program. We expect to complete this program and be in a position to make a final decision on any development in the March quarter of 2010.

"Sandstone has an amazing history of coming up with more gold just when we think it is about to run out. The mine has never had a forecast life longer than 3 years but recently celebrated its 10th year of consecutive production for Troy. Obviously our hope is that one of these targets will enable us to again extend the mine life."

In the drilling earlier this year the BIF was intersected on both sides of, and in close proximity to, the tonalite. The BIF unit cut by the stock dips to the northeast at about 30o and varies in thickness from 25m to 50m. The BIF is quartz veined and extensively replaced by pyrite. This latest drilling program targeted high grade BIF hosted gold mineralisation associated with the margins of the north-south elongated, gold bearing tonalite stock.

All assays have now been received for the 9 hole drill program consisting of Reverse Circulation (RC) precollars and Diamond Core (DC) extensions totaling 2,812.6m (248.4m in RC precollars; 2,564.2m in DC).

The recent drilling has highlighted the fact that the BIF hosted mineralisation is structurally controlled and is a difficult drill target. Two styles of sulphide (pyrite) replacement were noted in the recent drilling; a disseminated fracture infill style and a more massive "wave front" style. This drilling has confirmed that only the massive pyrite replacement, as bands or concentrations, is associated with high gold grades in the BIF. The disseminated style of pyrite mineralisation in the BIF yields only slightly anomalous gold values.

High grade gold mineralisation was encountered in several of the holes drilled to test the BIF on the west side of the Two Mile Hill intrusive and included:

- TRCD825: (up dip from TRCD733) 8.5m @ 49.59g/t Au from 195.8m

-- including 3.6m @ 91.68g/t gold from 195.8m;

- TRCD821: 7.8m at 3.2g/t gold from 199.2m downhole

-- including 2m at 9.1g/t gold from 205m downhole; and

- TRCD827: 4.75m grading 11.16g/t gold from 198.25m downhole.

Two mineralised zones were indentified in the BIF with the Lower Zone hosting the high grade gold mineralisation. In TRCD825 the Lower Zone intersection is only about 5m from the earlier intersection in TRCD733 and demonstrates how rapidly the character of high grade gold mineralisation can change from banded pyrite to massive pyrite over a short distance.

The 4.75m at 11.16g/t gold from 198.25m in TRCD827 is located 10m south of TRCD733 and TRCD825 high grade intercepts. This intersection is at the base of the BIF so equates to the Lower Zone.

Hole TRCD821 located 10m north of TRCD733 and TRCD825 intersected 2.0m at 9.1g/t gold from 205m within a broader zone of 7.8 metres at 3.2 g/t Au from 199.2.

On the east side of the tonalite a series of wide spaced step-out holes yielded only anomalous BIF hosted gold intercepts with the peak value being TRCD824A: 1m grading 3.2g/t gold from 230m downhole. However, gold mineralisation was encountered in quartz veins in the metabasalt to the east of the tonalite with a peak value in TRCD820 of 4.8m grading 48.26g/t gold from 114.2m downhole.

The best tonalite hosted vein intercept was TRCD824A: 1m grading 21.15g/t gold from 301m downhole

Complete results are compiled in Table 1 and displayed on Figure 1.

An eight hole follow-up program is planned to further test the BIF hosted gold mineralisation on both the east and west sides of the tonalite and will commence in January 2010.


The outcropping BIF in the Two Mile Hill – Shillington area was the focus of a detailed geological mapping and rock sampling effort to understand the structural controls on the gold mineralisation. Rock chip grab sampling of the outcropping BIF returned a best value of 5.12g/t gold taken from a small laterite pit on the northeast slope of the BIF outcrop to the southwest of the Two Mile Hill Pit (see Figure 2). Gold anomalism is centred around a north-northeast plunging synform-antiform in the BIF just to the northwest of the Shillington Pit. The high grade mineralisation in TRCD733 is interpreted to be in the down plunge position of this structure.

An earlier drilled RC hole, TMR045, tested the shallow position of the structure 47m down plunge, intersecting 3m at 14.78g/t gold in brecciated BIF. Additional RC drilling is proposed to the east and west of this hole as well as up dip to further define the mineralisation in this structure at a shallow depth. This new target, named Shillington North, will also be tested with a 12 hole RC program in the March quarter.
