Sandstone Exploration Update
Perth, Aug 24, 2016 AEST (ABN Newswire) - Alto Metals Ltd (
ASX:AME) are pleased to provide an exploration update on the Company's Sandstone Gold Project in Western Australia.
Highlights:
- Induced Polarisation (IP) surveys to better define drill targets associated with known unmined gold mineralisation to commence in early September
- Lord Nelson mineral resource [JORC 2012 compliant] being estimated by Snowdens
- Tenements expected to be granted on or about 18 September 2016
- Planned Programs of Work (PoW) for follow up drill testing of prospects with known high grade gold mineralisation to be lodged after grant of tenements
- RC drilling to commence mid-October following approval of PoW's by DMP
SANDSTONE 2016 INDUCED POLARISATION SURVEY
The Company has now planned IP surveys over areas of gold mineralisation identified in historical wide spaced drilling, to better define and extend targets for drill testing in the oxidised and primary (fresh - sulphide) zones.
This work is based on a review of historical IP data collected by Troy Resources NL (2004/2005) and Western Areas NL (2011) which shows gold mineralisation to be associated with chargeability and resisitivity ("high") anomalism. The data showed that IP can used to detect both oxide and primary mineralisation. The known gold mineralisation at Lord Nelson and Lord Henry is associated with zones of high resistivity and chargeability values.
The proposed IP surveys are is shown in Figure 1 overleaf (see link below). A total of 27 lines (61 km) 100m dipole-dipole are planned.
Priority areas are Lord Henry and Lady Hamilton. The Lord Henry area includes surveying at the Lord Henry deposits and the Horatio, Maninga Marley and Havilah prospects. The Lady Hamilton area includes Indomitable (north and south), Tigermoth, Piper and Musketeer (north and south).
IP is also planned over gold mineralisation at the Vanguard, Ladybird and Sandstone North prospects.
In 2011 IP data was collected by Western Areas to identify anomalous chargeable sources which may be associated with accumulations of matrix to disseminated nickel sulphide mineralisation. This data was not used to target gold mineralisation.
Alto has reviewed this data and has completed 2D inversion modelling, and has identified a number of new target areas and extensions to known mineralisation, that are considered prospective for both oxide and primary gold mineralisation. This work is on-going.
Figure 2 (see link below) shows depth slice of the 2D model chargeability (350m RL) which highlights primary mineralisation targets in the basement north and south of Lord Nelson, and north of Lord Henry, plus other targets. The red colours represent areas of high chargeability and the blue areas represent areas of low chargeability.
Target areas are shown in black ovals. These targets also have associated higher resistivity.
An example of an untested basement chargeability anomaly is shown in Figure 3 (red high chargeability and blue low chargeability) - (see Figure 3 in link below).
