Bastion Minerals Ltd (ASX: BMO ) (“ Bastion ” or “the Company ”) is pleased to report that a detailed high-resolution airborne magnetic survey has been completed at the Company’s flagship Capote Gold Project, located in the mineral-rich Atacama mining region in northern Chile. The processing and interpretation of this data has led to the identification of numerous high-priority targets on the 100% owned ground at Capote.
Highlights
-
1,473-line-kilometres of airborne magnetic and radiometric data collected at Capote
-
Program has identified multiple high-quality gold and copper targets across a range of geological and structural settings
-
New data highlights structures and extensional targets associated with historical highgrade gold deposits (San Juan), artisanal gold mining and historic high-grade rock-chips
-
Significant anomalies identified at previously recognised gold targets Yayito and Taquia
-
Project-scale rock-chip programme ongoing, initial results expected mid-April
-
Historic rock-chip data at Capote suggests there is potential for Iron Oxide Copper Gold (IOCG) and Silver-Lead Zinc deposits
-
Detailed data integration, interpretation and drill planning is underway
Bastion’s Executive Director, Mr Ross Landles, commented
“This is an exciting initial step for the Capote project. The first modern exploration technique used in this historically significant gold mining district. Airborne magnetic and radiometric is an effective first-pass prospecting technique that can detect deep-seated structures controlling high-grade gold mineralisation under shallow cover.
We have speculated for some time that the regional structures that control high-grade gold mineralisation at the San Juan gold mine extend north and south and this new data now confirms our beliefs and lays a solid foundation to continue our exploration activities. We expect to receive the first round of rock-chip assays shortly which will help support planning for drilling at Capote.”

Capote Airborne Magnetics
A helicopter borne magnetic and radiometric survey has been conducted over the entire Capote Gold Project (Figure 1). The objective of this survey was to map the key gold bearing structures at Capote and expand these beneath shallow soil cover and at depth (Figure 2). Regional magnetics can also provide lithological and alteration information to aid in mapping the mineralised system.
There are three components to the magnetic data and when processed using sophisticated modelling and self-organising maps (SOM’s) can clearly:
-
Separate out structures,
-
Highlight areas that are unusual (anomalous), and
-
Identify areas where the magnetic properties of the rocks have been changed through alteration and mineralisation (Figure 3).
Bastion is applying these cutting-edge modern exploration techniques to focus on areas in the region that show similarities to known high-grade mineralisation to make new discoveries.
Multiple new targets have been identified already and this data will be refined and continually reviewed to assist in providing a pipeline of additional targets for Bastion geologists to map and sample in the field.
Capote Field Work
Bastion’s first field campaign has been completed, focussing on along strike and outcropping vein sampling, and the second campaign is now nearing completion which will focus on the wider project area (Figure 4). Results are expected for the Campaign One in the second week of April whilst results from Campaign Two are expected late April/early May.
Field Campaign One
The objective of the first field campaign at Capote is to obtain a high density of rock-chip data along strike of existing rock-chipping and to sample as many outcropping veins as possible. This data will provide additional information required to design follow up trenching and drilling activities and is designed to highlight the areas most likely of hosting larger, high-grade gold deposits. Initial focus has been on the Yayito area, along strike of the San-Juan historic gold mine.
One-hundred and fifty-seven (157) channel and rock-chip samples have been collected in Campaign One and are being processed by ALS in Chile.
Field Campaign Two
The objective of the second field campaign at Capote is to step out into the broader region and test for a mix of targets (Au-Ag-Cu-Pb and Zn). The historic rock-chipping at Capote has suggested there is potential for Iron Oxide Copper Gold (IOCG) and Silver-Lead Zinc deposits as well. To ensure that this potential is assessed early in the project life 25% of the initial work at Capote will involve these target types.
One-hundred and eleven (111) channel and rock-chip samples have been collected to date in Campaign Two and are being processed by ALS in Chile.

Capote Gold Project
The Capote Gold Project consists of approximately 77km[2] of granted mining and exploration tenements surrounding the historic San Juan Gold Mine, approximately 20km northeast of Vallenar (Figure 2). Known mineralisation at Capote consists of high-grade gold found within quartz-carbonate-sulphide (iron oxide at surface) veins associated with north to northwest trending structures cutting the host granite and metamorphic rocks.

| computer via Ethernet cable for real-time monitoring. | |||
| • | SPECTROMETER | ||
| The RS-500 Airborne Spectrometer with RSX-5 detector | |||
| pack, manufactured by Radiation Solution’s Inc. (RSI), was | |||
| used for the survey. The RS-500 spectrometer has a multi- | |||
| peak gain stabilization algorithm and is capable of recording | |||
| 1024 channels with an accuracy of 0.1 to 10 counts/second. | |||
| The RS-500 is connected to a crystal pack comprising four | |||
| downward-looking crystals (16 liters total) and one upward- | |||
| looking crystal (4 liters total). The downward crystals record | |||
| the radiometric spectrum from 410 KeV to 2810 KeV over | |||
| 1024 discrete energy windows, as well as from a cosmic ray | |||
| channel that detects photons with energy levels above 3.0 | |||
| MeV. From these 1024 channels, the standard Total Count, | |||
| Potassium, Uranium and Thorium channels are extracted. | |||
| The upward crystal is used to measure and correct for | |||
| atmospheric Radon interference. The shock-protected | |||
| Sodium Iodide (Thallium) crystal package is unheated and | |||
| automatically stabilizes with respect to multiple peaks. The | |||
| RS- 500 provides raw data that has been automatically | |||
| corrected for gain, base level, ADC offset, and dead time. | |||
| • | IDAS DIGITAL RECORDING | ||
| The output of the CS-3 magnetometer, fluxgate | |||
| magnetometer, radar and laser altimeters, GPS coordinates, | |||
| and time (system and GPS), were recorded digitally on a | |||
| solid-state drive (SSD) at a sample rate of fifty times per | |||
| second (ten times per second for GPS) by the NSG iNAV | |||
| system. | |||
| • | PRESSURE AND TEMPERATURE | ||
| A Stellar Instruments pressure and temperature sensor, | |||
| model PT1702-20A-101, was used to record the ambient | |||
| pressure and temperature during the survey. The instrument | |||
| was used to record the absolute pressure and temperature | |||
| during the survey, and was mounted in the helicopter stinger. | |||
| The sensor’s units of measure were recorded in mbars | |||
| (pressure), and degrees Celsius (temperature). | |||
| • | SPECTROMETER DIGITAL RECORDING | ||
| The output of the RS-500 spectrometer, GPS coordinates and | |||
| time (UTC) were recorded digitally on an internal RS-500 | |||
| flash drive at a sample rate of 1 Hz. After each flight, the data | |||
| was copied and synchronized using UTC clock with the iDAS | |||
| digital records. | |||
| • | BASE STATION MAGNETOMETER | ||
| A Scintrex CS-3 optically pumped cesium split beam sensor | |||
| was used at a remote base installation Santa Lucia (close to | |||
| the survey area), Puno. The station was set up in an area of | |||
| low magnetic gradient as well as low cultural electric and | |||
| magnetic noise sources. The sensitivity and absolute | |||
| accuracy of the ground magnetometer is +/- 0.01 nT. Data | |||
| was recorded continuously at fifty times per second | |||
