QUARTERLY EXPLORATION AND ACTIVITIES REPORT

(For the period 1[st] April 2012 to 30[th] June 2012)

Sorpresa Gold Project Provides High Grade Gold Intersections in the Period

The gold mineralisation at the Sorpresa Area was the predominant focus for exploration within Fifield NSW in the June Quarter. Major attention was given to the Sorpresa Trench 31 and Boundary Gate Areas, the Sorpresa SW extension and the Yoes Lookout Area with ongoing percussion drilling.

Highlights for the June Quarter

Percussion OHH Drilling produced excellent high grade Gold results at Sorpresa

• 22 holes were completed at Tr31 and SW extension Areas, and 6 holes at Boundary Gate Area

• Highest Grade was Fi 160, 14m @ 21.9g/t Au from 34m, including 2m @ 87.5g/t Au, AND 6m @ 93.8g/t Ag

• During the quarter assay results added many of the best holes seen for Au at Sorpresa to date

The next 50 hole drill program has commenced and will include the following:

• Ongoing delineation at Tr31, Boundary Gate and Roadside Areas of Sorpresa

• Additional scout drilling in various locations

Yoes Lookout Gold Prospect completed 8 percussion OHH scout drill holes

• Assays were received on two holes to date, indicating minor Au, which is seen as encouraging

• An additional adjacent 7 exploration units in a new licence is due to be granted shortly to the Company

The IP Survey Results were represented and modelled at Sorpresa indicating important targets at depth

• Correlation to known geology and structure in the 0 to 60m zone gives credence to the IP survey

• Drilling to greater depths of 150m to 350m will be required to test the IP response adequately

• The “Greater Sorpresa Area” prospective for Au is now revised upwards from 4km[2] to 8km[2]

• Detailed geological mapping interprets a larger “Rift Basin Setting”, with Sorpresa just at the margin

• A model has been developed suggesting that in this area, multi-million ounce Au potential exist (Appendix 5)

• Further detailed regional exploration reconnaisance at greater Sorpresa has been undertaken

• Includes soil sampling, rock chips, structure mapping and auger drilling

• This work will provide guidance for additional drilling of scout percussion holes

Appendices (1 to 8) attached provide Locations, Context and Results relevant to this report.

In May 2012, the Company produced an inhouse field video review of the IP geophysical survey with respect to the Sorpresa Gold Mineralisation area. The video can be seen by activating the hyperlink: 3D model of the IP Anomaly at Sorpresa.

The Executive Chairman, John Kaminsky, reflected on the June Quarter:

“We have had an outstanding June Quarter, with delineation drilling in three areas at Sorpresa producing some of the best gold intersections yet seen at Fifield.

1

With a high grade in Fi 160 of 14m @ 21.9g/t Au, including 2m @ 87.5g/t , it confirms what we had believed originally, back in the discovery days of the original Trench 31 in 2010. Namely, that this system has a capacity to produce very high grade.

What’s more, I believe we have not yet seen the best grades this area will show us. The more work we do, the better the Au mineralizing potential continues to look.

The drilling conducted in the June Quarter is part of the regular drilling now occurring at Fifield. The weather conditions were difficult, but we still managed creditable progress.

The establishment of the size of the greater Sorpresa area, at 8 km[2] , is more than double the previous estimated size. Coupled with the geological context of the multi-million ounce potential the developed Rift Basin model could offer, the Company is extremely “Huge Au Potential” well placed in its outlook over the coming Quarters.

This is very significant progress and should be understood by those following the Company.”

The Head of Exploration, Colin Plumridge, explained:

“I concur with John’s appraisal, this was an exceptional period for the Company. The results continue to demonstrate what untapped potential exists at Sorpresa and the wider surrounds, within the newly defined 8km[2] .

The delineation drilling work at Sorpresa in the 0 to 60m zone will move towards defining gold resources in this zone. In parallel, I have focused on the bigger gold mineralizing picture.

The geological mapping and discovery reconnaissance field work I have been doing looks at the interpreted Rift Basin geology, including the black silica gold receptive horizon from this multi-million ounce perspective. It is this larger scale potential that really excites me.

I would suggest keen followers of our discovery work take the Rift Basin model development seriously, as it represents a geological framework that is reflective of a much greater underlying system of which Sorpresa is just at the margin. It is extremely pleasing to see the development of the potential of the area grow at such a pace and scale”

June 2012 Quarter Summary of Exploration Undertaken

Weather conditions in the quarter remained difficult on occasions for heavy equipment movement, nevertheless, significant exploration work continued.

Significant Au mineralisation continues to be confirmed at Sorpresa

• There is now a demonstrated capacity to host very high grade Au at Fifield

• The Trench 31 and its SW extension location in particular, currently has an open strike length of approx. 300m

• Many additional locations at greater Sorpresa are well placed for further exploration (Appendix 7)

• The 0 to 60m zone of the Au and Ag seen to date, is particularly attractive as a commercial target

The geological context at the wider Sorpresa area continues to grow, with the recent exploration re-inforcing the view that Sorpresa is part of a much larger mineralised gold system at Fifield. The Company interprets a Rift Basin setting with a capacity for the geology to provide extremely large ore deposits at the greater Sorpresa area.

Important Results for the Percussion OHH drilling at Sorpresa conducted in the June Quarter

The percussion drilling in the June Quarter at Sorpresa produced some excellent Au intersections at Trench 31 area, its SW extension and at Boundary Gate, placing many holes amongst the best holes drilled to date at Sorpresa (based on ranking measure of “linear gram-metres of Au”).

2

In addition, scout drilling (14 holes) was conducted at distances approx. 50m to 150m from the previous known Au intersection at SW Sorpresa. This was to assist in locating further prospective Au areas within the black silica geology, deemed to be the surface based gold receptive horizon.

Drilling depths were generally between 40m to 70m, with deeper targets at Sorpresa are yet to be drilled.

Important observations constructed into new geological model of the “Syncline Rift Basin” These samples cover the available parts of the rift basin where geochemistryis suited

Apart from the known Sorpresa Area, the Rift Basin is largely covered by shallow unrelated scree or alluvium. This means much of the basin is unsuited to surface geochemistry.

Those remaining areas where surface geochemistry is applicable have now been covered with soil and rock sampling. To achieve this coverage, 223 geologically selected soil samples and 125 geologically selected rock samples were taken. Geochemical anomalies will need sampling in addition to this.

The Sorpresa style of mineralization is subtle in appearance even at high grades . Hence the rock sampling must cover many different possibilities with the inevitable result that many samples may not reflect mineralisation.

Soil Sampling

Each sample was designed to test specific parts of the geology. The soil reliability was logged and will be used in the anomaly selection process. Each sample has been sent for a low detection level gold assay. Base metals, as gold pathfinders, have been read by field XRF machine.

The grasslands provided an unexpected grass botanical anomaly. It is possible that the chemistry of the receptive horizon is unfavourable for grass growth. These areas are noted on the soil logs.

Rock Sampling

Each sample has been geologically selected after extensive ground searching. The black silica of the receptive horizon was the prime objective of the sampling. This was often sampled via a muster of numerous rock chips rather than individual prospective pieces of the rock float. The black silica often proved reluctant to display its presence through the soil cover, hence detailed work was required in black silica areas.

A great diversity of breccia types were located and sampled. Sheared rocks were generally unable to form robust rock float and have as a consequence, been under sampled.

4

The gold assays will decide what areas are important. Whilst many areas look promising, visual inspection is not a reliable guide to the potential contained gold levels. The base metals, as possible pathfinders to gold will be analysed on the rock chip pulps with handheld XRF.

Not all black silica areas are expected to be gold bearing, but the important cross cutting shear positions that heavily influence the gold position potential within this geology, are the key.

The Company has learnt that the area within Sorpresa at Trench 31 represents a well-organized gold lens, detectible only because it was partly eroded to surface, thus enabling geochemistry exploration to discover its position. Many more gold lenses are anticipated to be sitting within the gold receptive horizon, including gold mineralization that is poorly exposed, awaiting discovery in the ensuing periods.

The objective of the Company is to cover the many prospective areas as fast and as effectively as possible, thus leading to quality target establishment for further deeper drilling, where appropriate. The Company will continue to report specific exploration outcomes from each of the prospective areas, as data is processed and properly interpreted within its appropriate context. This will feed into the subsequent customized exploration programs.

The Syncline Rift Basin Concept

Sorpresa style mineralization is hosted by a carbonaceous receptive horizon in the sediment pile. Faulting, shearing and brecciation provide the deep plumbing that allows the gold bearing hydrothermal fluids to gain access to this receptive horizon.

It is inferred that the receptive horizon has an overall syncline basin shape. In detail any one part of the basin has a buckled or complex shape. This is to be expected as the basin is criss-crossed by many faults.

The known mineralization at Sorpresa is only a small part of the prospective mineralisation likely contained within Rift Basin . As mentioned, Sorpresa was covered by residual soil and hence its discovery was greatly aided by soil geochemistry. By contrast much of the remaining Rift Basin is not suitable for soil geochemistry and will require drill based exploration.

The Company is learning to use the drill results to help refine the structural model and the basin wide work interpretations looking for repetitions and variations on the gold system geology, initially in the 0-60m zone.

The receptive horizon plan area has been ascribed various dimensions as the knowledge of the area increased. Initially, 4 km[2] was thought a reasonable estimate, but at this point in time, the best estimate is double, at 8km[2] . This is a large area by any standards and represents significant potential for large scale mineralization. The gold receptive horizon described by the Company, is a thick layer in the basin stratigraphy. The basin itself goes above and below the receptive horizon.

The delineation drilling at Sorpresa is showing that the Sorpresa gold mineralization style has good rewards for persistent drilling. It is entirely probable that thicker blocks of the receptive horizon exist in the basin centre . The basin is fault controlled and prone to isolated deep patches where an accumulation of organic carbon is likely to have historically occurred.

The Sorpresa area is on the edge of the basin, which in turn appears orientated with the known shear zone positions for Platina-Gillenbine.

The project area at Sorpresa represents a large gold exploration target that requires drilling from the near surface to hundreds of metres in depth. To date, the Company has undertaken drilling within the 40~60m depth range, where results provide significant encouragement to justify a far greater drilling density and also depth extension.

IP (Induced Polarisation) is an electrical geophysical method that demonstrates a strong capacity to direct the deeper drilling into the better mineralized areas. The IP chargeability can highlight minerals that can be electrically excited, producing a 3D image of the target areas to be tested.

At Fifield, the strong IP anomaly appears located at the centre of the syncline basin. This gives rise to the possibility of a huge mineralising system being present, and focused on the basin centre. The additional geological mapping undertaken in the June Quarter has provided greater interpretation of the geological model for the greater Sorpresa area and is shown in Appendix 4 .

The IP anomaly is likely to be due to graphite and pyrite developed on structurally deformed and compact organic carbon. This is likely the gold precipitation trigger that operates at the greater Sorpresa area in general.

The Rift Basin concept provides a broader context for the known area of gold mineralisation at Sorpresa, which is at the periphery of the Rift basin system. The Company must therefore undertake both delineation drilling at Sorpresa, as well as explore for the much larger scale mineralization, and its multi-million ounce potential likely to exist as part of the Rift Basin centre.

5

Continued Work Programs at Fifield

The Company strategy is to continue to have a mixture of discovery scout drilling, but also undertake resource definition drilling on the known Sorpresa gold mineralized areas, partly drilled in 2011 and 2012.

The next phase of drilling continues to cover delineation drilling of the Main Sorpresa Area (EA 1), looking at Trench 31 area, Boundary Gate and Roadside. Reconnaissance drilling will continue at Sorpresa SW extension, South of Sorpresa and Yoes Lookout. A range of other target areas at Fifield for Au mineralization (EA 2 to EA 11) are still marked for drilling, at various future stages.

The Trench 31 gold mineralization continues NE (Boundary Gate is 600m NE of Trench 31 Area) and SW along strike, but is intersected by cross cutting faults that distort the mineralization, with the possibility of enhanced gold mineralization as a result. The scout drilling attempts to anticipate the potential for any complex geometry in the distortions. The delineation drilling will subsequently close the mineralization gaps shown in the scout drilling.

Yoes Lookout

Yoes Lookout prospect (EA 11), located 5km due east of the Sorpresa Gold project area at Fifield NSW, had a traverse of 8 scout percussion (OHH) holes drilled looking for the gold mineralization seen in prior soil sampling and auger drilling. Two of the eight holes have been assayed and both have confirmed encouraging shows of Au at levels 0.2g/t Au.

Further holes are planned as part of an initial program to scope the area in the first drilling ever conducted in this area, by Rimfire, or any other explorer in the past.

The results in the March Quarter confirmed that a greenfields coherent Au anomaly in the soil was established, of considerable in size and open in many directions. The geology at Yoes Lookout is Upper Ordovician volcanics and appears to be the dominant underlying host rock style, which differs to that of Sorpresa.

Appendix 6

Notes on the Unique Geological Position of the Fifield Project Area

The district wide exploration work continues to find mineralisation zoning of various styles at Fifield. The eastern areas, which includes Yoes Lookout, have overlying Silurian-Devonian aged rocks which have been eroded to expose the underlying Upper Ordovician porphyry copper-gold style rocks.

The western gold areas at Fifield have Girilambone age rocks below the Silurian-Devonian rocks. Accordingly, it is postulated that somewhere below the Sorpresa Gold mineralised area, there is a massive fault contact between the Girilambone rocks and the Upper Ordovician porphyry copper-gold style rocks.

This important geological contact below the Sorpresa gold mineralised area is also cut by the Lachlan Lineament structure and is intruded by many and varied intrusives. It is also the site of a deep rift with highly carbonaceous rocks being deposited simultaneously with rhyodacite and basic volcanics.

A conceptual geological model is being developed to reflect this interpretation, which is seen as a Syncline Rift Basin setting .

The wider geological mapping and interpretation of the new Yoes Lookout area has provided an encouraging context to the Au anomalism. The geology at the Sorpresa Gold Project area differs to that of the Yoes Lookout area, where the Upper Ordovician volcanics appear to be the dominant underlying host rock style. The Yoes Lookout setting is closer to the porphyry copper-gold style geology that includes North Parkes.

Magnetite veining in altered andesite has been identified and a shear zone appears to be present, along the strike of the main corridor of the Au in soil anomaly at Yoes Lookout. A negative topographic expression of the main gold zone is evident.

Gold Potential is Growing

The Fifield area continues to develop its gold credentials. The turning point was the RC drilling that confirmed discovery of disseminated gold at Sorpresa in 2011, elevating the importance of the gold geochemistry and trench work done in 2010 at that location. Recent higher grades seen in 2012 continue to enhance the gold potential in the 0-60m zone.

Disseminated gold deposits appear evidenced to occur in this dynamic geological setting within the Fifield district, and this has gone largely unrecognised by all other explorers prior to Rimfire’s Sorpresa gold discovery.

The RC drill programs completed on the Sorpresa gold (Au) prospect during 2011/2012 and additional knowledge gained in the adjacent locations within the 20km[2] prospective area identified at Fifield NSW for gold mineralisation have formed the basis for geological model development using the important interpretation of the gold receptive horizon of black silica now identified.

Inclusive of the main Sorpresa prospect (EA 1), a 4km[2] area was identified as having a target potential of 0.5 million to 1.5 million ounces of Au.[2] Details of the basis for the assessment can be seen in the 2011 AGM Presentation[3] . The prospective area is now revised to be 8km[2] and growing.

The Company intends to continue its assessment and delineation of the Main Sorpresa Prospect, whilst advancing the development of additional areas for new Au discoveries. It is the Company’s firm view that the district is likely to host a range of gold discoveries, some similar in character to the Sorpresa area, so ensuring a suitable balance between new exploration and delineation is important. The overall geological setting and Au mineralised potential both continue to show impressive scale and promise in the wider Fifield district of 20km[2] .

Background on the 2011 RC Drilling Results at Sorpresa Main Strike EA 1 and Geological Model Development

The Company has considered the broader implications of the exploration to date at the Sorpresa area and its surrounds. This also included important observations from both the May and September 2011 RC Drilling programs.

On 23[rd] August 2011 the Company reported its highly encouraging final assay results for the first pass RC drill program conducted in April/May 2011 at the Sorpresa area, in 4 locations over a distance of approx. 1.3km focused on gold mineralisation.

The full results can be accessed at the hyperlink to the ASX release on 23[rd] August 2011: RC Drill Program Starts within 14 days At Sorpresa Gold Project

Sorpresa consists of disseminated gold and silver mineralisation with associated traces of arsenic (As), lead (Pb) and antimony (Sb) as reliable pathfinders. This was again consistently and clearly reflected in the round of RC drilling in September 2011.

The mineralisation is largely hosted by special parts of a 30m thick black, carbonaceous shale horizon . This horizon becomes replaced by pervasive silica during mineralisation to finally yield the distinct “black silica horizon”.

The extent of the black silica horizon is not yet fully defined, however, an area of 8km[2] is now indicated and growing as mapping continues to the south of Sorpresa. The gold mineralization appears disseminated, coherent and amenable to reliable assays with capacity for high grade.

Additions to this mineralized area are likely as exploration continues. It should be noted that the gold mineralization encountered continues to be located well outside of this indicated area, and not necessarily always within the proximal black silica. The mineralization has entered the black shale, black silica horizon via multiple, interacting shear zones. Hence, it is now concluded that the Sorpresa position is a large area of black shale that is receptive to mineralization and pervasive silica replacement. The multiple interacting shear zones provide numerous locations where mineralization hydrothermal fluids can access the receptive horizon.

This represents a highly promising geological context for large scale discoveries and confirms the Company’s earlier views that “Company Making” Au mineralization is likely to occur in this setting.

Whilst the full geological context at Sorpresa is still under examination, it now seems highly probable that an area of much larger gold potential exists at Fifield and is within a Syncline Rift Basin setting.
