From a friends suggestion I thought I would draw your attention to this resource from Heritage Victoria that details the history of gold in this geographical area "1850 - 1982"

Bethanga starts on page 19. A couple of key quotes for me are: "produced an average of over 8,000 oz a year from its mines on the southern Gift
line between 1897-1902."


and "Largely due to the success of the Bethanga Goldfields Co., Bethanga achieved the
highest total gold yield of any field in the Beechworth Mining District in the years
1899 and 1900. The other principal mine at Bethanga in those years was the
Centennial, yielding more than an ounce to the ton."


And that's using horses, steam engines and mostly pick and shovel.
