Geophysical survey at Labour Victory Mine, near Selwyn, Queensland
A geophysical survey, comprising self-potential and electromagnetic methods, was made during the 1952 and 1953 field seasons at the Labour Victory Copper Mine, about 7 miles north-north-west of the Mt. Elliott Copper Mine, near Selwyn, Northern Queensland. The self-potential survey covered an area of 2,400 feet x 900 feet, but owing to other operational commitments during the 1953 season, the electromagnetic survey was confined to the southern part of the area. The primary object of the work was to determine the extent of the mineralisation associated with the known lode, which strikes north-south through the centre of the surveyed area. The self-potential survey revealed a well-defined anomaly nearly 1,000 feet long, in the northern part of the area. The axis of this anomaly is parallel to, but about 75 feet west of, the known lode. The disused main shaft of the now idle mine is at the southern end of the anomaly, which in this vicinity deviates slightly towards the south-east, i.e. towards the known lode. No workings exist in the area of the indication, and no outcrops were found, the rock formations being hidden for the most part by alluvium. The electromagnetic results confirmed those of the self-potential survey, but the electromagnetic indication extends farther to the south. The results suggest that the indication may be caused by lenticular bodies and that these are disturbed by cross faults. No mineralised deposits were indicated by the electrical results in the southern part of the area. It is recommended that some trenching and geological and geochemical work be done in the area of the strong electrical indication. If the results of the testing show that the indication is not due to graphitic or pyritic schists, it is recommended that a number of diamond drill holes be put down. Suggested locations for five such drill holes are given. If the anomaly is due to ore the geophysical results suggest an ore body of considerable size.

Geology of the Mount Elliott copper mine Selwyn, Queensland
공공데이터포털
This report presents the results of detailed geological mapping of an area of approximately seven square miles surrounding the Mount Elliott copper mine, Selwyn, Queensland. The survey was made to determine the relationship between the geological structure and the mineralized zone containing the Mount Elliott copper deposit. A geological map of the actual exposures has been compiled (Plate 1) and interpretations of this data are shown on one plan (Plate 2) and eight sections (Plates 3, 4, 5 and 6). This report is intended as a supplement to the report by C.J. Sullivan (1951) and should be read in conjunction with it.
Geophysical survey at Mt Brown copper mine, Karangi, New South Wales
공공데이터포털
A geophysical test survey was made at the Mt. Brown Copper Mine, Karangi, N.S.W in October, 1954. The survey was undertaken by the Bureau of Mineral Resources at the request of the Mt. Brown Copper Mining Company, supported by the New South Wales Department of Mines, to assist in prospecting the leases for additional ore reserves. Reopening and developing the present workings is uneconomical without further prospects. Self-potential, electromagnetic and radioactive methods were used in the survey. The magnetic results show a distinct pattern, but this appears to be unrelated to the known deposit and cannot be interpreted satisfactorily until a regional geological survey of the area has been made. It is recommended that this be done. No self-potential anomalies or electromagnetic indications which could be caused by an ore body, were obtained in the surveyed area. Parts of the area were unsuitable for electromagnetic work because of the effects of electric power lines. The very weak variations observed in the self-potential values are accounted for by small local surface effects. .Random radioactive readings over the area gave no indications of radioactivity above background level.
Geophysical survey at Silver Valley, Copeton, New South Wales
공공데이터포털
This report describes a geophysical survey made in May 1952 and August 1953 at the Silver Valley mine workings, near Inverell, N.S.W. From the workings there is evidence of mineralisation along a well-defined fissure and one ore shoot has already been partly developed. The survey was made in an attempt to locate other ore shoots of sufficient size to warrant mining operations. Self-potential, magnetic and electromagnetic methods were used in the survey. The self-potential method showed a well-defined anomaly on the eastern extension of the fissure, indicating that a small body of sulphides may exist there with its centre about 300 feet east of the known ore shoot. The magnetic and electromagnetic results showed no pronounced anomalies which could be correlated with any defined ore shoot. Recommendations are made as to how the self-potential anomaly could best be tested. These comprise sinking a shaft at the centre of the anomaly, extending an existing adit, or driving a new adit from a point nearer the anomaly.

The area was geologically investigated at the request of the Director of Mines, Alice Springs, by A.D.M. Bell and J. Firman. Mapping was by chain and compass traverse during periods 29th to 31st October, 1952; 4th to 6th November, 1952 and 19th December, 1952. Previous geological reconnaissance was made by B. Thompson of the Enterprise Exploration Company in 1948.
Geophysical investigation of the copper-nickel deposits, North Dundas field, near Zeehan, Tasmania
공공데이터포털
In response to applications by the Tasmanian Department of Mines and the interested company, Eagle Metal and Industrial Products Pty. Ltd., Tasmania, a geophysical investigation, including self-potential, electromagnetic and magnetic surveys, has been made over the copper-nickel deposits of the North Dundas Field, situated about 5 miles north-east of Zeehan, Tasmania. The nickel ore occurs in the foot-wall of north-striking ultrabasic dykes. The ore shoots already worked had proved very rich but quite small. Important results were obtained in the Cuni North Area only. Conductive indications which appear to be due to mineralization extend over a length of 800 to 1000 feet. The line of mineralization is intersected by cross faults. Drilling targets for five short diamond drillholes are given. Further exploration should be confined mainly to this area. The geophysical results indicate that mineralization farther south is limited in extent and perhaps of no economic interest.

The period 7th to 28th January, 1951 was spent at Selwyn by the writer: approximately one week was spent in preparing a semi-regional map at a scale of 1 inch to 400 feet; one week was given to mapping a smaller area at a scale of 1 inch to 40 feet. Level plans have been constructed showing what are considered to be the broad outlines of ore arrangement and structure and a number of sections have been constructed. Nineteen plans and sections illustrate this report. Twelve typical ore and rock specimens were studied in thin section and the information obtained has been incorporated in this report. An account of the regional geology of the prospect and the geology of the ore deposits is given in this report.
Geophysical test survey over dykes in the Newcastle Coalfields, New South Wales
공공데이터포털
Results are given of a geophysical test survey made at three localities on the Newcastle coalfield in August, 1952, to determine whether intrusive doleritic dykes could be located by the magnetic method. Knowledge of the position of the dykes would assist in planning the lay-out of underground workings and of surface roads. The results showed only slight variations of the magnetic field, but some weak anomalies of less than 100 gammas were recorded. The position of these anomalies coincides with the inferred position of the basic dykes near the surface. The variation in the shape of anomalies suggests non-uniformity of the magnetic properties and shape of the dykes. The magnetic method might be helpful in determining the position and extent of the dykes beyond the areas where they are known, but supporting evidence from other geophysical methods such as the gravity of electric resistivity methods may be needed to verify the magnetic results.
