TAS Terra Ventures

Terra Ventures Inc. (TSX VENTURE: TAS)(FRANKFURT: G7K) is pleased to provide an update on the Midwest Northeast Uranium property in which Terra owns a 10% production carried interest. In a press release dated November 30, 2010, Hathor reported:

"Hathor Exploration Limited (HAT: TSX-V) is pleased to announce the updated and upgraded mineral resource estimate for the Roughrider Uranium Deposit located on its Midwest NorthEast property, Athabasca Basin, Saskatchewan. Details are provided below in Table 1. Other attributes of the Roughrider uranium deposit include:

--  Approximately 60% of the mineral resource is in the Indicated category.
--  Conceptual Whittle pit optimization indicates 99% of the mineral
    resource is amenable to open pit extraction.
--  Metallurgical extraction recoveries of 98% have been reported previously
    for the Roughrider deposit (see News Release dated June 16, 2010).
--  Low As (arsenic) levels are confirmed.
--  Average depth to the top of the deposit is approximately 215 m.
--  Nearly all mineralization is located within basement rock.

This mineral resource estimate does not include Roughrider East. It is located 200 m east along strike. Once final assays for summer drilling at Roughrider East are received, geological models will be developed and preliminary resource models will be evaluated. Roughrider East represents further significant upside for the overall resource potential of the project.

Table 1 below shows the Mineral Resource Statement ("MRS") for Roughrider as determined by SRK Consulting (Canada) Inc ("SRK") based on an ordinary kriging (OK) estimate.

The exploration database for Roughrider is robust. It is based on based on 174 drill holes exceeding 60,000 m completed in five successive summer and winter drill programs starting in 2008 (Figure 1). Drill hole separation varies from less than 10 m in the core zone to approximately 25 m elsewhere in the deposit (Figure 2). The Roughrider data base includes 24,300 sample intervals assayed for U3O8 and other metals (including arsenic, cobalt, copper, molybdenum, and nickel), and more than 420 bulk dry density measurements obtained in the field.

Roughrider uranium deposit is a robust, high grade uranium system.

As shown on Figure 3, the major attributes of the deposit are concordant and predictable, including: 1) the alteration envelope; 2) mineral deposit outline (120 ppm U3O8); 3) outer low grade mineral resource shell (0.05% to 3% U3O8), and; 4) high grade core zone with grade greater than 3% U3O8. All attributes have a long axis of approximately 080 degrees to 090 degrees azimuth, with a moderate dip (30 degrees to 40 degrees ) to the north. In plan view, the deposit is up to 220 m in length and 100 m in width. In section view, the mineral zones span a thickness of up to 55-60 m. The following data highlight the strength and continuity of mineralization at Roughrider:

--  High grade mineralization intersected and delineated on virtually all
    twenty cross-sections spaced 10 m apart along the entire 200 m length of
    the deposit.
--  618 chemical assays over 3.0% U3O8.
--  7,000 chemical assays over 0.05% U3O8.
--  Bulk dry densities of mineralized rock range from 1.74 to 5.51 g/cc.
--  Wireframe models outline eleven high grade wireframes and four low grade
    wireframes. All high grade domains are contained in one main low grade
    wireframe solid (Zone 100).

Figure 4 is a grade/tonnage plot which shows the similarity of resource estimates using ID2 and OK interpolations. As such, Table 2 and Figure 4 reinforce that mineral resource estimation for the Roughrider deposit is not sensitive to analytical approach.

Mineral Resource Statement

The Mineral Resource Statement for Roughrider was constructed by SRK Consulting (Canada) Inc. A completed technical report prepared following Canadian Securities Administrators' National Instrument 43-101 and Form 43-101F1 guidelines is anticipated for early January, and will be available on SEDAR within 45 days of this News Release.

The boundaries for uranium mineralization were modelled by SRK using a preliminary Hathor interpretation of high and low grade domains, and wireframe grade shells generated with LeapFrog software. The Leapfrog grade shells were generated using a three percent U3O8 thresholds for the high grade domain and a 0.10 to 0.05% threshold for the low grade domain. SRK used both the Hathor interpretation and Leapfrog shells to generate a wireframe outline of high and low grade uranium mineralization on vertical sections spaced by 5 to 10 m. SRK generated eleven high grade wireframes and four low grade wireframes that were considered for geostatistical analysis, variography and grade estimation.

The database considered for resource estimation consists of 149 drill holes comprising approximately 24,300 sample intervals with chemical assays for U3O8 and other metals (including arsenic, cobalt, copper, molybdenum, and nickel) and approximately 420 specific gravity measurements. All assay intervals within the high grade and low grade wireframe solids were composited to 0.5 m to provide common support for analysis and estimation. SRK evaluated impact of high grade outliers in each zone using cumulative probability plots, histograms and examining the spatial distribution of higher grades with respect to other drill holes and adjacent composites. SRK concludes that no significant assay outliers are present in the database, thus no grade capping of assays was applied.

Variogram model radii for resource estimation were restricted to 20x20x2 m for the high grade zones and 20x15x15 m for the low grade zone. A sub-blocked model for the Roughrider project was generated using Datamine Studio 3. The block model coordinates are based on the local UTM coordinate grid (NAD 83, Zone 13). The parent block size is 4 by 4 by 2 m and is sub-blocked to 1.0 m in the X and Y directions and 0.002 m in the Z direction.

The estimation strategy for the Roughrider deposit consists of estimating U3O8 and other elements, and specific gravity into a block model informed from composited data and constrained by fifteen resource domains. Uranium oxide (U3O8) grades were estimated using three estimation runs. The first estimation run is based on a search ellipse with ranges equal to the largest variogram model structure the second run consists of a search ellipse range equal to twice the variogram range. The third estimation ellipse consist of a search ellipse generally three times the search ellipse range. The bulk of blocks are estimated in the first run. Second and third estimation runs adds only about 18 and 9% more material, respectively.

SRK tested four estimation methods for density to ensure that the variability in the data set can be approximately replicated in the estimate. The three estimation methods used are:

--  Moving average using a 30 m sphere for averaging;
--  Global kriging of entire composite data set for each zone as well as all
    each data set for high and low grade domains, using ordinary kriging;
--  Direct estimation of specific gravity composites using ordinary kriging;
    and
--  Estimation of the product of specific gravity and U3O8 composites using
    ordinary kriging, followed by dividing the estimated product by
    estimated U3O8 grade.

An examination of density estimates results by Hathor and SRK indicates that the direct estimation of specific gravity composites appears to produce the most reasonable results maintaining the variability of the original composites. Global kriging is the next best result. Potentially deleterious elements arsenic, cobalt, copper, molybdenum, and nickel were estimated using ordinary kriging. Variogram models for U3O8 were assumed for these metals. Estimates were verified by conducting checks on Zones 5 and 100. Verification procedures included visual examination of block grades to drill hole composites, and comparing estimated grades at zero cut-off to nearest neighbour estimates and declustered means for the two zones. All validation checks confirm that the block estimates are appropriate and reflect the underlying borehole sampling data.

All block model estimates were full block estimates with full block values assigned to sub-blocks.

Mineral Resources for the Roughrider uranium project have been classified according to the "CIM Standards on Mineral Resources and Reserves: Definition and Guidelines" (December, 2005), by G. David Keller, P. Geo (APGO#1235) an "independent qualified person" as defined by National Instrument 43-101, who has reviewed the technical aspects of this News Release related to the Resource Estimate. Resource classification criteria include drilling density, variography results and estimation run. All blocks in Zone 100 are classified as Indicated because this zone is well informed by drilling spaced at 5 to 10 m and blocks were estimated with U3O8 grades entirely by the first estimation run. Zone 5 is also well informed by data spaced from 5 to 10 m with the exception of the extreme northwest portion of the Zone which is not well informed by drilling. This area was manually assigned an Inferred classification. Zone 2 was classified according to estimation run; first estimation run estimates was classified as Indicated with all other blocks classified as Inferred. All other zones were classified as Inferred because they are informed by limited data.
