Geita Property

• The Geita Project covers an area of 257.25km2, and includes 3 Prospecting Licenses. These are all wholly owned by Tanzania Royalty Exploration Corp.
• The majority of the project area is underlain by granite, with showings of granodiorite, inliers of greenstone and associated BIF, in addition to Bukoban-age conglomerates and dolerite dykes. RAB drilling in specific areas has revealed sequences of gabbro, basalt, sediments and quartz porphyry, with rock textures varying from massive to mylonitic, with rare to minor low-grade metamorphic overprinting.
• Initial exploration focused on PL 3274/05, which was extensively sampled along a surveyed grid, using both conventional soil and MMI (Mobile Metal Ion) geochemical techniques. All samples were assayed for Au only. A single dipole-dipole IP survey was carried out to test the cause of a large MMI anomaly, which was confirmed to be shears and faults within a greenstone host. Soil sampling geochemistry highlighted several targets within PL 3274/05, which provided the locus for two RAB programs. The initial program was a 262 hole RAB drill program, which totaled 4436m of drilling. The program was designed to initially test the MMI anomalies. Highlights of this program include 2m @ 2.18g/t Au and 3m @ 1.09g/t Au. A second RAB drill program was initiated, aimed principally to test structural targets within PL 3274/05. Some 164 holes to total 6175m were drilled. The highest value intersected was 3m @ 1.23g/t Au. No further work is planned.

Regional Geology:

The Geita Project Area is located within the Geita Greenstone Belt in NW Tanzania, and its surrounding granitoids. It comprises four licences of which three occur within predominantly granitic terrain and one is located within the volcano-sedimentary pile of the Nyanzian System. The Project Area comprises 310km_

The Geita Greenstone Belt lies within the Lake Victoria Gold Belt. The southern portion (the Sukumaland greenstones) consists of two oval, concentric belts separated by granite. The inner belt comprises mainly mafic volcanic rocks of the lower Nyanzian System and the outer (Geita) belt consists of chemical sediments and intermediate to felsic rocks of the upper Nyanzian. An outwardly younging age relationship between the two concentric belts is generally accepted (Borg, 1994).

Principal Structures:

Locally the region consists of large open NW-SE trending folds that have sub-horizontal fold axes and are the result of D1 (ductile deformation). Regionally the D1 fold axes follow the oval shape of the two parallel belts within the Sukumaland Greenstone Belt. The Geita portion of the Sukumaland Greenstone Belt is characterized by a widening of the exposed greenstone belt. Interpretation of satellite imagery and aeromagnetic data indicates that large-scale z-folding has caused this widening (Borg, 1994). The anticlines, both in the Geita area and in the Sukumaland greenstone belt in general, have cores of banded iron formation (BIF) forming large resistant ridges within the region.

With Anglo Gold taking over management of the Geita Gold Mine, some 5km east of the Tanzania Royalty Exploration Corp. Lukalanga license, new structural models have been proposed for these deposits. Refer to the Anglo Gold website at www.anglogold.com for further information.

Geology of the Prospecting Areas:

PL2506/04: This license has an area of 50km_ and is covered almost entirely by granite, with the possibility of a small portion of greenstone in the NW corner of the license. Two NE trending Bukoban dykes crosscut the granite.

PL1951/02: This license has an area of 100km_ and is located 15km south of Geita. The license is underlain predominantly by granite, and Bukoban conglomerates have been recorded by Pangea Goldfields who conducted soil geochemical programs and stream sediment sampling. Anomalous gold from soils was recorded from the Bukoban.

PL3274/05: Known as the Lukalanga License, and has a surface area of 100km_. Granodiorite is exposed along the southern boundary of the license with minor sub-crops of BIF and tuffaceous units along the northern boundary. The Kukuluma deposit, a shear related stratabound deposit hosted by a folded BIF sediment package (±2 mil. ounces), lies approximately 4km NW of the northern tenement boundary.

Extensive RAB drilling has revealed sequences of gabbro, basalt, sediments (carbonaceous siltstone and chert) and some quartz porphyry and granodiorite. These rock types show a range of features from massive through to mylonitic (typically closer to the granodiorite contact) with rare to minor low grade metamorphic overprinting. The majority of the lithological contacts are WNW trending, almost parallel with the regional foliation trend of 270o to 300o, dipping steeply (60o-90o) south.

An aeromagnetic interpretation has delineated a major shear, which trends NW through the center of the license with a dextral displacement of approximately 4km. This shear is cross cut by an ENE-trending shear, which appears to have no displacement. The greenstone sequence shows evidence of regional N-S compression resulting in folded units with adjacent shearing. Northwest faulting has later displaced the sequence. Granodiorite intrusions occur on the southern and northeastern edges of the license.

Geochemistry

The first phase of exploration on the Lukalanga license (PL 3274/05) was a conventional soil sampling program commonly referred to SOIL 1. A total of 866 samples were collected on a 300x150m grid, 1 foot below the surface with no sample collected over granite or in transported material. The samples were dried and sieved to --80# and sent to XRAL for Au analysis. Four significant anomalies were thought to be present, which indicated 2 different types of gold enrichment (Earle, 1996):

• Type A: occurs in the southeast corner of license and is characterized by strong gold enrichment (10-20ppb) along a NNE trend within a larger area of moderate gold enrichment (5-8ppb).
• Type B: are isolated Au rich samples (>13ppb) surrounded by low Au levels which in places extend over two or more sample lines.

A follow-up soil program was undertaken to infill anomalous areas defined by SOIL 1. This program is commonly referred to as SOIL 2. Samples were collected on a 100x100m grid in between areas of previous anomalism. The samples were sent to XRAL laboratory in Canada and assayed for Au (ppb) by fire assay. Results from this follow-up survey intensified the original anomalies.

A MMI (Mobile Metal Ion) soil program was completed in 1996 with a total of 4459 soil samples, collected at 30cm depth, with a duplicate taken every 100 samples. Samples were collected on a 100x100m grid from 0E to 4200W after which it was then increased to 200x100m sample spacing. The samples were prepared at SGS in Mwanza then sent to XRAL in Canada and analyzed by MMI-B for Au, Co, Ni, Pd, and Ag (ppb). Thirteen anomalies were highlighted and tested with a RAB drilling program

Due to skepticism in MMI as a regional exploration tool a conventional soil program was completed in the NW corner of the license where there is very little drilling.

A total of 5334 soil samples were collected on a 200x40m grid and sent to HUMAC for Au (ppb) analysis by wet assay.

Geophysics

PL2506/04, PL1951/02: Geodass flew an aeromagnetic and radiometric survey in 1999. This forms part of a larger survey which is at present not for the public domain.

PL3274/05: On Lukalanga, an aeromagnetic survey was conducted by Geodass in 1996 using a Scintrix H8 cesium vapor magnetometer, to record data at 8m intervals with a line spacing of 100m. The flight trend was NE-SW.

The only other geophysics carried out was a dipole-dipole IP survey conducted in 1997 on Lukalanga where a total of 12.7 line kilometers were divided into 7 N-S lines. The aim of the survey was to try and define the cause of large MMI anomalies to reduce the amount of RAB drilling. Targets identified by the IP were potential shears or faults within greenstone (Lotter, 1997).

Drilling Results

PL3274/05: Two RAB drilling programs were conducted in 1998 and 2000:

1998 Program:

262 RAB drill holes (GERAB1-207, GERAB300-354) were completed for a total of 4436m. The aim of the RAB drilling was to investigate the source of the 13 MMI anomalies and map the underlying lithology. A total of 2088 samples were collected and sent to ACME laboratory for Au, Cu, and Ag analysis by fire assay and wet assay respectively. Two drill holes returned encouraging results: GERAB4: 2m @ 2.18g/t Au from 6m, and GERAB352: 3m @ 1.09g/t Au from 7m.

2000 Program:

A total of one hundred and sixty four (164) RAB holes measuring some 6175m were drilled and composite sampled at 3m intervals. Samples were submitted in batches to the HUMAC Laboratory in Mwanza for gold assaying. The following targets were selected:

• A large isoclinal fold of greenstone with interpreted shears cross-cutting the limbs, situated between two large granite plutons. The RAB holes intersected a sequence of granodioritic to granitic rocks overlain by a transported cover with an average thickness of 15m. Hole LURB 256 intersected a chert unit with 1-2% pyrite within granodiorite. Generally, minor quartz veining observed tends to occur close to contacts between granodiorites and more felsic sequences (granite). No significant gold values were intersected in this RAB section.

• Some of the previous 1998 RAB sections were re-drilled, as the previous drilling could not penetrate the overburden. Minor anomalism was apparent in bedrock. The RAB drilling in this section intersected basalts with sections of intermediate medium grained (gabbroic texture?) rocks, overlain by transported clays and ferricrete averaging 10m thick. In the southern part of the section, intense fracturing accompanied by quartz stringers and vein infilling were evident especially in zones of transition from the basaltic sequence into medium grained intermediate sections of the sequence. Holes LURB175 and LURB176 showed consistent elevated gold values at the base of transported clays, in contact with basalt. Elevated gold values (6m @ 0.1g/t) were intersected in hole LURB178 containing sheared and highly fractured basalt with hematite staining in fracture surfaces. Possible contamination of down-hole samples by top wet material was noted. In results from hole LURB 181, where a zone of 6m representing contact between transported clays and basalt, had elevated values of gold averaging 0.1g/t.

• An ESE-striking synform (?) within the Upper Nyanzian BIF sediment package on the Northern edge of the License area. A magnetic lineament is present along the limb of the fold. Drilling along this section line mapped out dominant basalts to the S, in contact with predominant granodiorite around 12250E. The contact zone is marked by intense alteration and shearing accompanied with pervasive silicification. Notably, the granodiorite body exhibits a marked increase in biotite away from the contact with the basalts. Holes drilled ranged from 10--70m close to the contact area, while generally the overburden material ranged from 15--30m thick. No significant gold mineralization was intersected.

• A folded mafic unit nears the granodiorite contact that has an interpreted shear along the fold axis. Only two holes in the northern end, intersected granodiorite with the rest of the section dominated by basalts interbedded with intermediate volcanics. Overburden material averaged 10m in thickness, and in the southern most part of the section, rocks are outcropping and in places covered by a thin layer of mbuga cotton soils. Three soil anomalies were tested in this area and were explained by low order gold values in the RAB holes: LURB132 averaged 3m @ 0.2 g/t and hole LURB 133 averaged 3m @ 0.42g/t. Chips from the mineralized zones were observed to contain up to 3% pyrite). The third anomaly, located north of this section, had an intersection of 6m @ 0.2g/t Au in basalt from hole LURB 142, showing characteristic silicification and quartz veining with up to 1% pyrite.

• A large magnetic high, possibly an intrusive rock, which occurs adjacent to a sheared granite contact and has a coincident NE striking, 27ppb, conventional soil anomaly. Holes in this section intersected a sequence of basalt and a granite intrusive. Rocks near the contact zone are weathered and show evidence of intense shearing. Of note is strong quartz veining and K- feldspar alteration around the contact zone. Most of the RAB holes averaged 20--30m depth while the overburden cover was generally thin averaging 5--10m thick. No significant gold mineralization was intersected in this line section, though a 3m zone of 1.23g/t Au was intersected in transported clays.
