Abbotts comprises 13 granted tenements that cover about 450 square kilometres, surrounding and abutting Thundelarra's Garden Gully Project.
Thundelarra chairman Phil Crabb said the acquisition of the exploration ground was extremely significant for the junior.
"It means that the company now controls what we believe to be the last large piece of remnant greenstone belt in the Yilgarn craton.
"History shows that these geological settings have the potential to deliver spectacular results.
"Systematic exploration - using the latest geophysical and exploration techniques to explore beneath the surface cover and test for possible repetitions of Crown Prince - means that there are exciting times ahead for our shareholders."
The acquisition will put Thundelarra's combined project area at about 530 square kilometres, more than quadrupling the aggregate strike extent of the prospective target settings.
Abbotts and Gardeny Gully are about 20 kilometres northwest of Meekatharra in Western Australia's Murchison region and within 30 kilometres' trucking distance of two operational gold pants.
Thundellara will undertake a detailed review of all the Doray exploration data and incorporate the information into the current geological model that is has developed around the Crown Prince and other Garden Gully prospects.
Results from July 2018 at Garden Gully's Crown Prince prospect revealed 3.25 metres at 18.5 g/t gold from 107 metres and 11 metres at 4.9 g/t gold from 42 metres.
Crown Prince has a proven production history with 20,718 ounces grading 21.7 g/t gold mined historically.
Drilling at Crown Prince intersected grades of up to 66.5 g/t gold across multiple holes and showed that gold mineralisation went down to at least 245 vertical metres.
Notably, Thundelarra’s first drill program extended the Main Lode to at least 130 metres below the base of the old workings, with the high grades continuing at depth.
