Lundin had recommended buying the shares 13 times in the newsletter between October 2005 and September 2015, and he bangs the drum again for the Mexican silver producer in the latest issue.
Lundin argues that the firm is coping well with the low metal price environment, with revenue in the third quarter rising to $16.8mmln from $12.8mln the year before on the back of an impressive increase in production to 1.08mln ounces of silver equivalent from 890,641 ounces a year earlier.
Encouragingly, cash costs per silver ounce fell by 41% year-on-year while all-in sustaining costs fell 32%.
Lundin says the trend of these two key metrics is a positive for Great Panther, and it should feel the benefit when silver prices rally from their currently low levels.
The company has plenty of exploration potential, Lundin notes, and is cracking on with its drilling programs at its Guadalupe de los Reyes and Coricancha projects, plus its flagship Guanajuato mining complex.
Gold Newsletter is now in its fourth decade and claims to be the oldest and most respected precious metals and mining stock newsletter in the world.
Shares in Great Panther currently trade at 63 cents in Toronto, and rose 3.3% on Tuesday.
