REVIEW OF GRACE GOLD COPPER PROJECT GEOPHYSICS
Highlights
-
Grace Gold Project is located 25km to the southeast of Newcrest’s world class Telfer Mine (32Moz gold 1mt copper).
-
Large untested IP anomalies along the Grace-Bemms shear.
-
Significant untested magnetic anomaly southeast of GraceBemms shear
-
Shallow Inferred Gold Resource previously defined over portion of known mineralised Grace-Bemms shear zone
Paterson Resources Limited (“Paterson” or “the Company”) (ASX:PSL) is pleased to announce a comprehensive review of historical geophysical data on the 100% owned Grace Gold Copper Project which demonstrates significant untested Induced Polarisation (IP) anomalies and open ended gold mineralisation at the Grace deposit. The Grace tenements which includes multiple gold prospects is located 25km southeast of Newcrest’s 32Moz Telfer gold-copper mine (Figure 1). The most advanced of these being the Grace deposit, originally discovered by Newcrest in the 1970’s.
A previous detailed geological review (PSL - ASX Announcement 23 January 2018) captured all existing drilling and geophysical exploration data relating to the Grace tenements representing the first time in over 40 years that the Grace Project has been consolidated under the ownership of an ASX listed entity.
An Inferred Mineral Resource estimate of 1.59mt @ 1.35g/t Au (PSL ASX Announcement 20 February 2018 *) was calculated from the historical drilling on a shallow portion of the mineralised zone covering 1,140m strike length from within a much larger total strike length of known gold mineralised zone extending over 4,130m along the Grace-Bemms shear zone. Additional exploration and infill drilling on the full 4,130m strike along the Grace-Bemms shear zone has the potential to expand and increase the confidence level of the known Resource.
(* - The Company confirms that it is not aware of any new information or data that materially affects the information included in the previous announcement. All material assumptions and technical parameters pertaining to the resource estimate continue to apply and have not materially changed)

Figure 1. Grace Gold Project PSL tenements located 25km to the southeast of the Telfer gold mine.
The Grace Project area is located approximately 25 km southeast of the Telfer gold mine in Western Australia and consists of a sub-greenschist facies regional stratigraphic sequence of quartz rich sandstones and interbedded siltstone/dolomite units of the Malu and Isdell Formations (Figure 2). Hydrothermal breccia zones cut the layered stratigraphy and gold mineralisation is associated with quartz-dolomite-pyrite veins and hydrothermal breccias. Highly altered metasomatised dolerite intrusives occur locally throughout the project area and play an important role in overall fluid architecture and ultimately gold deposition.

Figure 2. Regional geology of the Yaneena Basin of the Paterson Province with PSL tenement outline in yellow, showing folded and faulted sedimentary and igneous host rocks, with young sedimentary cover in blue, larger mineral deposits and prospects, and the Grace-Bemms shear zone as a dashed red lin.
High grade shallow oxide gold mineralisation commences from surface. In general transported cover (i.e. sand dune and/or colluvium) is thin over the project area. Drilling has been on a close spaced drill pattern (i.e. 25 to 100m, generally spaced 50m apart along northeast-southwest sections, with a 10m to 20m “northwest-southeast” spacing on section). The base of complete oxidation from weathering generally occurs between 20m to 60m below the surface, below which transitional and primary sulphide gold-copper mineralisation occurs.
Grace oxide mineralisation is variably open along strike and at depth associated with shallow dipping en-echelon stacked vein sets and a large vertical stockwork of hydrothermal breccias along the Grace-Bemms shear. At the Grace deposit, high-grade primary gold remains open in all directions and the potential for further high-grade copper mineralisation also remains prospective. Drilling is generally shallow at Grace and the sparse deeper drilling is broad spaced resulting in geological and assay data suffering from ‘information
==> picture [218 x 69] intentionally omitted <==
effect’, as many holes stop within the mineralised zone at Grace and the sparse deeper drilling is insufficient to have adequately tested the continuity of gold mineralisation at depth and along strike.
The Grace Prospect presents a compelling exploration opportunity:
-
Mineralisation intersected to a depth of 510m vertically below surface in isolated drilling at the Grace deposit;
-
Regional Dome structure and mineralised Grace-Bemms shear central to project area, and includes the Bemms, Grace, Grace East, Genoa, Kestral, Halls Knob and Lakes prospects;
-
Drill intersected gold mineralisation occurs along 4.1km of strike and remains open;
-
Potential for an additional parallel fault structure not yet tested;
-
Bimodal vein distribution evident as a series of stacked vein sets and a vertical stockwork of hydrothermal breccias;
-
Predominantly shallow drilling to date with average drill hole depth of 73.4m Grace gold deposit zones, within a large regional dome structure interpreted to be of the same style as the large mineralised system at the Telfer gold–copper–silver deposit located 25km to the northwest;
-
Existing Induced Polarisation (IP) survey data correlates strongly with existing drilling and mineralisation showing multiple additional high order anomaly zones that remain untested, as well as a strong northwest to southeast trending magnetic anomaly zone running parallel to the main Grace trend and which has not yet been tested by drilling into the source of the magnetic anomalies;
-
100% owned by Paterson and not subject to any net smelter royalties; and
-
Further multiple exploration targets outside of the immediate Grace prospect area identified by Paterson, as well as Newcrest Mining such as Trane and Lincoln.
Geophysics - Induced Polarisation
Newcrest Mining completed two Induced Polarisation dipole-dipole (DPIP) surveys at Grace during 1988 and 1997. In 1988, a 50m DPIP survey was undertaken over the Grace East Prospect (WAMEX Report A24465), and in 1997 a 100m DPIP survey was undertaken over the Lakes Prospect (WAMEX Report A53741). The IP survey line locations are shown in Figure 3 below, with re-processed and depth modelled IP chargeability anomaly cross-sections for survey lines 11300mE, 14500mE and 14800mE shown in Figures 4, 5 and 6, respectively. No digital data were recovered, so the IP data were digitised from raw data pseudo-sections provided in historic reports and plans. The digitised IP data were then modelled using UBCDCIP2D inversion software.
An IP anomaly responses of chargeability highs occurs in all re-processed and re-modelled cross sections at depth, forming northwest-southeast trends between survey lines. Chargeability anomalies at depth suggest the presence of sulphide minerals, predominately pyrite, pyrrhotite, chalcopyrite and arsenopyrite, occurring within dolomitic siltstone host rocks. Gold-copper mineralisation is associated with sulphide minerals zones, and the chargeability anomalies clearly shown in Figures 3, 4, 5 and 6 represent excellent drilling
==> picture [218 x 69] intentionally omitted <==
targets. Furthermore, the potential sulphide zones are generally associated with higher resistivity values below a less resistive (more conductive) zone of weathered bedrock, where the lower resistivity at depth is interpreted to be caused by intense quartz and carbonate brecciation and silica alteration. A depth slice of chargeability anomalism at 225m RL, or about 75m to 100m below land surface, was generated from 2D inversion model results, and is shown in Figure 3 as coloured image areas. The mineralised Grace-Bemms shear corridor is clearly defined by a chargeability high trend in the eastern survey area, with a similar chargeability zone evident over the Lakes area which is parallel and offset to the south of the Grace-Bemms shear zone, potentially increasing the overall width of the gold mineralised corridor at Grace. Both IP anomaly trends remain open along strike.
The IP chargeability anomalies have not been fully drilled both along strike and at depth. The historical IP survey results have limited depth extent, with the 50m DPIP detection to only approximately 150m in depth, and the 100m DPIP detecting to approximately 300m in depth. Better data quality and depth penetration can be achieved with modern IP survey systems, and the Company is planning further IP surveys over the project area, such as gradient array and offset DDIP surveys, to comprehensively map the two parallel chargeability anomaly trends and identify the scale of deeper IP anomaly responses to help target for much larger scale gold-copper mineralised systems in the project area.

Geophysics - Aeromagnetics
High resolution aeromagnetic survey data acquired at 100m survey line spacing show an anomaly high trend following the Grace-Bemms shear zone, indicating hydrothermal magnetite and pyrrhotite altering the dolomitic siltstone host rocks, and this is possibly related to intrusive igneous rocks or intense hydrothermal alteration of host rocks at greater
==> picture [218 x 69] intentionally omitted <==
depth (Figure 7). Just south of this magnetic anomaly trend is a parallel magnetic anomaly trend with very strong magnetic anomalism (Figure 7). This large magnetic anomaly zone has not yet been tested by deep enough drilling identify the source for the anomalies, which could be caused by magnetite and/or pyrrhotite related to hydrothermal alteration or igneous intrusive rocks forming a skarn contact with the host rocks, and both of these potential sources for the magnetic anomalies could be associated with gold-copper mineralisation at depth.
Similar magnetic anomalies in the Paterson region are associated with hydrothermal goldcopper mineralisation, such as Havieron (Newcrest - Greatland Gold JV) and Calibre (Rio Tinto – Antipa Minerals JV), or tungsten-zinc-lead skarn mineralisation at O’Callaghan’s (Newcrest).

Grace magnetic anomaly image (TMI reduced to the magnetic pole and NE sun angle) showing a moderate strength anomaly trend following the Grace-Bemms shear zone in the north, and a much stronger intensity magnetic anomaly trend in the south and running parallel to the Grace-Bemms shear zone trend (dashed black outline). This large and intense magnetic anomaly zone has not yet been tested by deep enough drilling, and it could be related to hydrothermal or igneous intrusive rocks associated gold-copper mineralisation at depth.

Telfer and Minyari Analogue
The world-class Paterson Province is known to host huge economic gold, copper and uranium deposits such as Newcrest’s 32Moz Telfer gold-copper-silver mine, O’Callaghans tungsten-base metal deposit, Metals X’s Nifty copper mine and Cameco and Mitsubishi Development’s Kintyre uranium deposit. The Grace deposit and dome structure at Grace, is interpreted by the Company to be a direct analogue in style of gold–copper mineralisation as the Telfer mine located 25km to the northwest. Further gold discoveries in the Paterson Province Yaneena Basin include Antipa Minerals 867Koz Calibre deposit and 723Koz MinyariWACA deposits. The Grace gold mineralisation is outcropping at the Bemms Gossan and throughout the remainder of the project area only a thin veneer of transported cover material is present, including sand dunes and colluvium.
Similarities between Grace, Telfer and Minyari mineral systems include:
-
Domal fold structure setting (i.e. Telfer Dome, Minyari Dome);
-
Host rocks; i.e. the Malu and Isdell Formations including favourable (chemically and structurally) carbonate bearing units (e.g. the Telfer member);
-
Gold-copper sulphide mineralisation style as defined by initial drilling at Grace;
-
Structural controls on the distribution of mineralisation involving “blind” thrusttip controlled “monocline” fold structures and hydrothermal breccia shear zones; and
-
Proximity to intrusive dolerite and granite bodies, and NE trending deep crustal shear architecture.
Grace Telfer Project Summary
The Company’s focus is to systematically explore the Telfer District projects which includes the advanced Grace asset and the considerable regional greenfields tenement applications covering 367 km².
On review of existing drillhole data it is evident that a series of shallow dipping en-echelon stacked vein sets are related to gold mineralisation and have not yet been adequately tested at Grace. There is a strong geological case that supports further gold mineralisation to be found in additional stacked vein sets along strike and at depth. Furthermore, the vertical stockwork hydrothermal breccias present an exciting new type of gold target at Grace which have potential to increase the resource tonnage potential of the Grace prospect.
The Company is currently working up an exploration programme for the area which will include geochemical surveys, IP geophysical surveys and drill targeting on gold mineralised extensions and structural targets, IP anomalies and magnetic anomalies.
