The Senn Block of mineral claims located in the District of Kenora, Ontario, Canada, covers an area of 1968 hectares and adjoins Rainy River Resources Ltd.'s Off Lake property, where a number of VMS-type base/precious metals occurrences have been found. Very little previous work has been done on this block. The nearly 4000 acre property is located 17 kilometres north east of the Rainy River deposit.
Current resource estimates at Rainy River are:

These resources are provided for informational purposes only and relate only to a property in the general vicinity of the property subject to option by the Company. It does not indicate that any mineral reserve or resource is located on the properties of the Company. These resources have not been independently verified by Brandenburg and therefore they should not be relied upon as they relate to properties of the Company.)
- Indicated resource - 2,370,000 ounces at 1.3 g/T Au,
- Inferred resource - 2,659,000 ounces at 1.2 g/T Au
- At a cut off of 0.4 g/T (open pit) and 3.0 g/T Au (underground)
The bedrock geology of the property is comprised of the 2.7 billion year old Rainy River Greenstone Belt in the Superior Geological province in northwestern Ontario. This belt is composed of volcanic rocks on Brandenburg Metals' property. These volcanics are composed primarily of mafic flows and dacitic volcanic rocks. Minor diorite and granite intrusive rocks are also in the area. Felsic intrusive rocks generally surround the volcanic rocks of the Rainy River Greenstone Belt.
Historical work in the area has included a geophysical survey. This survey included magnetics, VLF and horizontal loop electromagnetic surveys. Previous work in the area has also involved prospecting and mapping. The neighbouring Rainy River Resources property has seen significant historical work including drilling. This was done primarily by Nuinsco.
