You can stop looking now. Ihave found them in an old folder of songs that had been collecting dust in a corner of my study.
I'm still not sure of the author, though.

I have a pick I have a pan
I have a dog with one brown eye
I have the shoes upon my feet
That's all I have until I die.

A glass of rum to soothe my heart
There's not much more a man can need
And if there were 'twould be no use
There is no gold on Eureka Lead.

To make my fortune finding gold
I left a girl behind in tears
Isaid that I would come home soon
But I've been here for fifteen years.

Now with my dog with one brown eye
I suppose I'll keep on wandering
Far from the girl I love I'll be
And still the years a-squandering.
