The company had tipped achieving a record year in November after reporting its best monthly gold result in October and saying production was typically higher in the December quarter.
It had originally hoped to produce between 90,000-94,000oz in 2018 but this was revised to 82,000oz at the start of the fourth quarter, with Dynacor saying the decrease was mainly due to lower average grade ore supplied during the year.
The company processes ore bought from small-scale artisanal miners and said it produced "environmental and socially responsible gold" through its PX Impact programme, with supportive firms paying a small premium which provided direct investment to develop health and education projects in the miners' communities.
Dynacor is targeting 82,000-92,000oz in 2019 and is also waiting on an exploration permit, applied for in the first quarter of 2018, to drill at its Tumipampa property.
It said its 2018 production result was "a yearly best" and 1.8% more than its 2017 result of 79,897oz.
It reported a net income of US$4.8 million, a 26.3% increase on 2017, and its eighth consecutive year of profits.
Dynacor paid its first quarterly dividend in October of C1c per share, and has since declared further 1c dividends in November and March.
It had US$19.7 million in working capital at December 31 and $13.9 million in cash.
Dynacor shares have ranged from C$1.41-$1.97 over the past year and last traded at $1.63, putting its value at $64 million.
