The vender will receive a Net Smelter Royalty (NSR) of 2%. It should be noted that South Korea has no government royalties.

- Share price climbed to high of 30 cents, over 300% since placement and warrants up over 200% before softened in the last week with the rest of the market. Real value is returning to the company as shareholders are recognizing that the new management are mine operators and developers who wll take the company forward unlocking value in Sangdong, one of the worlds historically great Tungsten mines and Muguk gold that closed when gold price fell and remains the country's largest historical gold producer with leases over a significant gold field.

- To allow ease of trade in our shares the Company will be adopting Direct Registration System with Computershare Trust Company of Canada. The Direct Registration System ("DRS" is system which allows its shareholders' securities to be held in "book-entry" form without having physical security certificates issued as evidence of ownership).

- Company name will be changed to Woulfe Mining Inc as Oriental Minerals Inc which marks the new beginnings for the company. The name Woulfe is from Peter Woulfe who defined the element tungsten.

Core Projects

Sangdong – Tungsten and Molybdenum

- Meetings with government and stakeholders held this month were very positive and reached informal agreement of mutual cooperation to work together to move Sangdong forward as quick as possible.

- Independent Geological and Environmental review currently taking place of core assets.

- Wardrop engineers has been appointed to produce a scoping study of two options due early March 2010. The past concept Option One for a large 7 million tonne mine and Option Two a smaller higher grade underground operation using the existing access, ventilation and possibly tailings dam which will allow for rapid project delivery. The mine was operating till 1993 and has significant infrastructure in place such as a mining town that has only 600 people remaining against a peak of 20,000, roads, power, water, tailings dams and an area that was the location of the process plant that was removed. This is a great advantage in the reopening the mine.

- The Phase 1 mine plan will be drafted in conjunction with the scoping study. This plan will involve reopening underground, short drilling from underground, trial mining and bulk metallurgical sampling for test work. Noting that ore was treated for 40 years at an average recovery of 70% and mining operations were conducted making the operational risks far lower than un-mined projects.

Muguk Gold

This is historically Korea's largest gold mine and had produced at a long term average head grade of 8 g/t when it closed in 1997. Independent assessment of historical channel sampling data i from 1353 assays from underground mine workings from the Samhyungje vein suggest that the vein was between 0.3m and 2.7m in width with an average width of 1.15m and an average sampled gold grade of around 30g/t. The median gold grade of these samples is 13.9g/t with a value for the highest assay at the 95th percentile of 104 g/t. tIf the data is regularized to metre x grams the average is around 30m.g with a median value of 16.2 and a value at the 95^th percentile of 102g/t. The sampling methods and quality control procedures are undocumented for this data so it must be treated as purely an historical guide to mineralisation as it does not comply to NI43101 standards. It is however very encouraging. At the time of closure the "Reserve" estimated to Korean national standards by KORES (an agency of the Korean government) was given as 1.4 million tonnes at 13.5 grams of gold and 72.8 g/t silver. This does not comply with the requirements of NI43-101 in Canada and should not be considered to comply. It is included in order to give an indication of the tenor of the mineraliasation to be tested. There are an additional 99 NQ size diamond drill holes from the surface. When analysis of all available data iis complete drilling will be carried out with twin holes of some of the previous KORES holes to verify the voracity of the drill hole data base and exploratory holes to assess the extent and quality of the of mineraliasation which has veins known to extend f for a distance 2.5 km .

About Oriental Minerals

Oriental Minerals is a TSX-V company that gained control of a significant portfolio of resource assets in South Korea, mostly mines that had closed when metal prices fell in the nineties. The asset base makes Oriental Minerals the largest foreign resource company in South Korea.

New management is focused on building a mining company and unlocking the value of the assets and their strategic location within 100kM of the large manufacturers of South Korea.

We are focused on reopening the Sangdong mine, deploying modern mining technology for the efficient extraction of ore. Metal will be won by gravity and flotation methods before value adding the product into APT which carries a premium over concentrate.
