Field Course in Ore Prospecting,

Pernå, southern Finland

23-28 October, 2016
organized by
Krister Leon Sundblad

University of Turku

The course is sponsored by a number of companies and organizations and carried out in cooperation with Pernå Church and Rune Nygård

Warmly welcome to the 15th version of the annual Field Courses in Ore Prospecting, organized 23-28 October 2016 by the University of Turku.

A soil sample is put into the car on the first Field Course in October 2002, at that time organized in Lenhovda, SE Sweden. Antti Joutsen, Jens Rönnqvist and Marcelo Imana. Photo Gustav Westerlund.

The course is organized in an area with old mining traditions. In 1612, mining was carried out on the Forsö island, which resulted in a small amount of silver for the Pernå church.

We are very grateful for the economic support that has been received for the 2016 course from a number of mining and exploration companies in Finland and Sweden. Without this support, this course could not have been organized.

Target area

Since 2005, the field course has been organized in Pernå (Pernaja), west of Lovisa, c. 90 km east of Helsinki in southern Finland.

During 2005-2006 and 2015, we investigated the ore potential in the Svecofennian rock associations around the ancient Forsby silver mine and during 2007-2013, we concentrated on In-bearing polymetallic mineralizations in Rapakivi granites.
In 2016, we will concentrate on two different geological environments: mainly the Svecofennian supracrustal environments, on both sides of the Pernåviken bay, but we will also have one target area inside the rapakivi batholith.

Target areas 2005-2016

We will overnight at Kuggom, north of Lovisa town, some 10-30 kilometres from the various field work areas.

Kuggom, how to get there

Kotka and

Sankt Peterburg








Activity areas since 2005. You will get to Kuggom by driving:

a) from Helsinki eastwards on highway 7 (E18); green colour on the map, towards Lovisa, where you turn to the left (Lappträsk) and go for 5 km to the Kuggom facilities (marked in blue).

b) from Sankt Petersburg westwards towards Kotka and further on highway 7 (E18) (red colour on the map) until you get to the western exist to Lovisa (and Lappträsk), where you turn north and go for 5 km to the Kuggom facilities (marked in blue).

Field course area 2016


Overnighting will take place at Kuggom, located 5 km north of Lovisa town.

There will be an option to be served breakfast and dinner at Kuggom for a limited amount of money (yet to be calculated). The aim is that this shall be a more inexpensive option than any other realistic alternative.

It is also very important that every one who has any food allergy or any other kind of diet concerns reports this to me at the latest on October 15.

All lunch food shall be bought by your self and is eaten in the forest.

Transports and target areas
Most of the fieldwork areas are located south of the highway on each side of Pernåviken (within the big rectangle in the map above), 20 km west of Lovisa, accessible by small gravel roads. One target area is located on the northern side of the high road, northeast of Forsby (within the small rectangle in the map above), also accessible by small gravel roads
Turku, Åbo, Riga, Tartu and Sankt Peterburg teams will arrive with their own cars/ minibuses. During the field course days, we need to be flexible on who is going in what car depending on the work sites for each group.

What to bring?
The field course will take place in the forest (and on the farm fields) and appropriate field clothes, including rubber boots, rain coat and sweater are highly recommended. It may be cold and some of the equipment that you will carry consists of heavy metal pieces that easily chill down the hands, so warm gloves are also useful. You should also bring appropriate eating tools (plastic plate/fork/knife/cup) for the lunches and dinners. If you have a small backpack to carry all your things (and samples) it will facilitate your work. For the overnighting, you need your own bed sheets and towel.

As mentioned above, the course is sponsored by several mining and exploration companies but still, each participating student needs to pay for the food but the costs for the breakfast and dinner are not yet calculated.
Lunch food during the daytime is organized according to your own desire and expense.

Late October weather in Finland can be anything, in the worst case snow, in the best case cool and dry (sunny) days.
What the weather finally will become in reality remains to be seen, but be prepared for wet and cold conditions…

If you have questions, please write to or call me at +358405587373.

Warmly welcome
