On the recommendation contained in a preliminary report issued by the Bureau of Mineral Resources in 1952, a magnetic survey was made of several deposits of magnetite in the parishes of Puggoon and Tallawang, near Gulgong, N.S.W. The magnetic results are compared with test results from the quarry at the nearby Tallawang deposit and it is shown that the small deposits studied are not likely to be of sufficient interest to the present lease-holders. Attention is directed to the Tallawang deposit where it is possible that further development of the known ore-bodies, will expose additional reserves of magnetite. A detailed magnetic survey of the area is recommended.

Geophysical surveys of the magnetite deposits of Australian Magnetite Pty. Ltd. at Gulgong were made by the Bureau in 1952 and 1953, and revealed that the Tallawang deposit was the most important one. The present report gives the results of a detailed magnetic survey which was made over this deposit in August, 1953. Results show that three concentrations of very strongly magnetic material exist within the Tallawang deposit. The southern concentration is unlikely to contain considerable reserves beyond those in sight. The central concentration has been partly worked and could yield reserves of ore from the west wall of the quarry. The northern concentration, which has not been worked, could yield limited reserves. It is shown that the deposit, as a whole, pitches northwards. Some exploratory drilling is recommended on each of the three concentrations.

Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose. This Western Australia onshore plus marine magnetic grid geodetic has a cell size of 0.0025 degrees (approximately 266m). The units are in nanoTesla (or nT). The data used to produce this grid was acquired in 2005 by the WA Government, and consisted of None line-kilometres of data at Nonem line spacing and Nonem terrain clearance.
