Anglesey Mining's (LON:AYM) 15%-owned associate Labrador Iron Mines Holdings Limited has announced that the previously announced joint venture agreement with Tata Steel Minerals Canada Ltd for the exploration and development of LIM's Howse iron ore deposit in the Schefferville region of the Labrador Trough has been finalised.

The Howse deposit is located in Labrador about 25 kilometres north of LIM's currently producing James Mine and Silver Yards processing facility and adjacent to TSMC's Timmins area mines and new processing plant. The Howse deposit has a historical resource of 28 million tonnes at a grade of 58% Fe (natural basis).

Under the terms of the joint venture agreement, TSMC and LIM have agreed to form an unincorporated joint venture pursuant to which Howse Minerals Limited, a wholly owned subsidiary of TSMC has acquired an initial 51% participating interest in the Howse property for a total cash consideration of $30m.

LIM chairman and chief executive John Kearney said: "Completion of the Howse joint venture agreement with TSMC is an important step forward for LIM and will significantly fast track the development timeline for this new mine.

"We are very pleased to be co-operating with Tata Steel, one of the world's major steel companies, in this venture and we look forward to working with TSMC to advance the Howse project into production."

Sirius Minerals (LON:SXX) has announced a maiden ore reserve for the York Potash Project comprising a probable ore reserve of 250 million tonnes of polyhalite with a mean grade of 87.8% polyhalite.

This was derived from, and was a sub set of, the indicated mineral resource reported in May of 820 million tonnes at an average grade of 87.3%. The indicated resource is derived from just 1% of the project area of interest.

It said the ore reserve provides for a Phase 1 mine life of more than 50 years. Sirius added that there was potential for mine life to double following underground exploration of the Inferred Mineral Resource.

Obtala Resources (LON:OBT), the natural resource investment and development company, has signed a Heads of Agreement with the Lesotho National Development Corporation after being selected by it to enter into a partnership to manage and operate a fruit and vegetable cannery operation and supporting farm services within Lesotho.

Shanta Gold (LON:SHG), the East Africa-focused gold production & exploration company, issued an update on progress achieved with its 2013 diamond drilling programme commissioned to expand the Indicated category resource base at the Company's two main ore deposits, Bauhinia Creek and Luika, at the New Luika Gold Mine.

Highlights:

- Mineralisation consistently intersected at levels below that of the currently defined Indicated Resource

- Continuity of previously identified payshoots confirmed at depth and along strike

- High grade intersections including 10.42m @15.02 g/t achieved at depth

- Significant new mineralised strike extensions at Bauhinia Creek identified at depth and to the west of the currently defined orebody

- New high grade intersection achieved at depth and to the east of the currently defined Luika South deposit including 4.52m @ 13.10 g/t

KEFI Minerals (LON:KEFI) has confirmed a 33% increase in the JORC compliant inferred resource at its Jibal Qutman prospect in Saudi Arabia.

The company says its ongoing trench channel sampling and drilling programme at the Jibal Qutman licence continues to expand the mineralised system, which is yet to be closed off.

Kefi Minerals is the operator of the project under the company's 40%-owned Gold & Minerals joint venture.

The company says the JORC compliant inferred resource of 14.5Mt at 0.89g/t Au for 415,000oz Au has been calculated at a cut-off of 0.2g/t Au with the 3K Hill prospect discovered in June providing a significant contribution to the upgrade.

Kefi says a second phase reverse circulation drilling programme is on-going with mineralisation remaining open along strike at the Main, South, West and 3K Hill zones.

Drilling aims to extend the resource, and continues returning encouraging intersections, including: 9m at 14.20g/t Au, 25m at 1.25g/t Au, 10m at 2.18g/t Au, 9m at 1.36g/t Au and 8m at 1.01g/t Au.

Trench channel sampling over a newly discovered set of shear zone-hosted quartz bodies at 4K Hill returned encouraging intersections, including 8m at 1.03g/t Au, 12m at 1.37g/t Au and 1m at 28.31g/t Au.

And Kefi says a diamond drill hole programme to deliver samples and progress metallurgical testwork has been initiated.

Managing director Jeff Rayner said: ""The results of the on-going RC drilling and trenching at Jibal Qutman continue to increase the size of the mineralised system. We are very excited about the potential to develop a significant resource in the region and once more the drilling results have vindicated our team's efforts.

"Our drilling is continuing to find more gold and we have yet to close off the mineralisation along strike of any of the drilled areas. Additional drilling capacity is being sought to step up the work rate at Jibal Qutman with the continued focus on moving towards a pre-feasibility study. We look forward to further developing our drilling programme and updating the market in due course."

Fresnillo (LON:FRES) has reported on the temporary suspension of Minera Penmont's explosives permits (at Dipolos, Soledad, Herradura and Noche Buena).

It said last month that the local magistrate in Sonora issued requests to the Ministry of Defense which resulted in a temporary suspension of Minera Penmont's explosives permits.

Minera Penmont has presented legal proceedings before authorities requesting re-activation of its explosives permits outside Dipolos (at the Soledad, Herradura and Noche Buena mines) and is of the opinion that the explosives suspension is excessive since it goes beyond the area of land pertaining to the original court order around the El Bajío litigation.

The magistrate has instructed a court appointed expert to determine the boundaries of the area of land pertaining to the original court order and to submit a written report clearly delineating these boundaries. The company has obtained confirmation that this report has been received by the magistrate who is expected to reach a decision quickly.

Fresnillo believes that given the fact that the report submitted by the court appointed expert establishes the boundaries of land, there is no further dispute over the same and therefore expects that the suspension be lifted by the beginning of October although no assurances can be made.

Separately, it has complied with the original court order and vacated the land at the Dipolos open pit and has dismantled and removed the plant, and is working on relocating it to Herradura.

Last month Fresnillo reduced full year gold production guidance to 465,000 ounces as a result of the El Bajío litigation and expected no impact to production from Herradura and Noche Buena as a result of the explosives suspension as there were sufficient inventories at Herradura until early August and at Noche Buena until late August.

Although the inventory of blasted mineral which is hauled to the leaching pads at both mines has been run down to date, Fresnillo reiterates the 2013 full year gold guidance of 465,000 ounces as the leaching pads continue to process ore at the normal rate and the company expects to make up any production short fall by the end of December, subject to the lifting of the explosives suspension by the beginning of October.

Highland Gold Mining (LON:HGM) posted net profits of $17.0m for the six months to the end of June - down from $47.99m last time - despite increased production.

Revenues fell to $157.0m from $161.4m and earnings before interest, tax, depreciation and amortisation dropped to $63.3m from $71.5m.

Production rose to 105,630 ounces of gold and gold equivalents - up from 101,900 oz - and the company sold 110,424 ozs against 102,036 oz a year ago.

The company said total cash costs were a highly competitive US$717 per oz reflecting the costreduction programme initiated in the second half of last year.

Production guidance for 2013 is maintained at 225,000 - 240,000 oz of gold and gold equivalents.

Non-executive chairman Eugene Shvidler said: "Despite unfavourable market conditions throughout the first half of 2013 the group's underlying financial performance was positive. This reflected the quality of the group's asset portfolio and the effectiveness of the cost saving measures implemented by management to mitigate the effects of the sharp decline in the gold price during H1 2013."

SolGold (LON:SOLG) has begun drilling at a second hole at Alpala, which forms part of its exploration at Cascabel in Ecuador.

It currently holds a 50% interest, and can earn up to an 85% interest, in Exploraciones Novomining "ENSA"), an Ecuadorean registered company, which holds 100% of the Cascabel concession in northern Ecuador.

Cascabel is located in an under explored northern section of the richly endowed Andean copper belt.

Alpala exhibits surface mineralisation and alteration patterns indicative of porphyry copper gold systems and has a similar footprint to large porphyry systems around the world.
