Firebird currently controls over 1320 acres on the Jefferson Project under 10 lease agreements. As at Buzzard, Firebird is in the process of expanding this land package. The project lies just east of the Brewer mine and remains relatively untested due to a cover of younger Coastal Plain sediments over about 50 percent of the project and a cycle of several companies conducting exploration.
An Amax-Phillips joint venture conducted limited work on the property in 1982-83 including two core holes. Amselco completed 16,000 feet of geophysical work including IP, VLF, EM and MAG. In 1985, Westmont did some surface trenching and mapping. The property was then acquired by Dean Vaughan Associates and leased to International Viking Resources Inc. In 1989, Watts Griffis & McQuat (WGM) drilled 311 air rotary or "auger" holes totaling 18,500 feet on the Vaughan property. The sampling was to drill through the sand cover and collect a sample of the underlying saprolite; thus a deep soil sampling program. Unfortunately the work was poorly supervised with little quality control due to inexperience and many holes did not test below the sand cover as intended. Never the less, three targets were defined.
In 1990, the Phase I Diamond Drilling Program recommended by WGM was completed with 13 core holes drilled for a total of 3,833 feet. In 1992, the Phase II Diamond Drilling Program of International Viking Resources Inc. was completed. It consisted of four core holes totaling 1,571 feet.
The Table below summarized significant results from all prior known core drilling. Twenty two holes and 7329 feet (2443 meters) of drilling have been completed on the project

In 1994, the property was optioned to Inter-Rock Gold who conducted further evaluation including establishing approximately 10 line miles of grid for project control and ground geophysical surveys. Review of prior data resulted in drilling 57 shallow reverse circulation drill holes totaling 2505 meters. These holes focused on eight geophysical targets and eight geological targets. This shallow drilling (average depth 30 meters) provided encouraging exploration results with 32 percent (18 holes) of the holes having intercepts with greater than 250 ppb gold, 16 percent (9 holes) having greater than 150 ppb gold and an additional 14 percent (8 holes) contain intercepts greater than 90 ppb gold. These holes identify six anomalous areas of gold mineralization Three of these were new targets including, the Pipeline Anomaly with significant gold values up to 0.065 opt Au. Drilling extended and increased gold intercepts in the A Anomaly and the old Leach Mine.
The follow table summarizes significant RC drill intercepts for the historic drilling at the Jefferson Project. For this type drilling, the results are very positive.

- The A-Leach Anomaly contains "ore-grade" gold mineralization scattered across a number of holes. The total zone of alteration and mineralization represents a target about 2000 feet (650 meters) by 400 feet (135 meters) with limited drilling only to a depth of 300 feet (100 m).
- The Pipeline Anomaly is a new discovery with significant gold intercepts.
- There are six additional targets based on drilling within the project area
- Large areas of the project remain untested.
