The funding package from North American syndicate Franco Nevada and Osisko Royalties validates an estimated US$3.2 billion (AU$4.78 billion) net present value (NPV) at an after-tax internal rate of return (IRR) of 24 per cent as outlined in SolGold’s prefeasibility study (PFS) in March. Interestingly, the study is comprised of some conservative metals prices for copper at US$3.85 (AU$5.75) per pound and gold at US$1750 (AU$2611) per ounce.

The syndicate has no doubt run some back-of-the-envelope calculations in its valuations, perhaps using the recent all-time price highs for copper and gold, which are more than 25 per cent and 40 per cent higher than those used in the PFS, respectively.
A close second placing this week goes to Labyrinth Resources, which jumped 280 per cent after revealing its plan to acquire 100 per cent of two gold projects in Western Australia’s Goldfields region. The well-timed announcement, which saw the company’s stock rise from a 0.5c close last week to 1.9c, coincided with gold hitting its record high.

The deal will see Labyrinth acquire Ramelius Resources’ Vivien gold project and also affords it the option to acquire the remaining 49 per cent of its Comet Vale gold project.

Comet Vale, just 32km south of Menzies next to the Goldfields Highway, features a recently-updated mineral resource of 96,000 ounces at 4.8 grams per tonne gold. Labyrinth is aiming to bolster the high-grade resource inventory and capitalise on its new underexplored, high-grade mines.

A 4.8g/t gold resource is nothing to poke a stick at by WA standards. Just last month, emerging Murchison major Westgold Resources penned a
“strategic alliance” agreement with junior explorer Ora Gold to gain access to its 240,000-ounce Crown Prince deposit that runs at an impressive 4.1g/t.

Labyrinth has also raised $2 million through a placement and will present existing shareholders with an additional $2 million entitlement offer to support its endeavours to expand its high-grade resources and hopefully follow in Ora’s footsteps.

Taking out bronze, a fitting alloy for a story with a majority copper flavour, is Miramar Resources. The company’s share price jumped almost 188 per cent – from 0.8c to 2.3c – after revelations of promising high-grade copper, lead and silver samples from its Joy Helen prospect within its new Chain Pool project in WA’s Gascoyne region.

The project, while still not granted, shows plenty of potential after returning rock chip assays going up to 5.49 per cent copper, 42 per cent lead and 73.48g/t silver. Despite the impressive at-surface numbers, management says the Joy Helen prospect has seen no modern and systematic exploration, nor drilling.

The mineralisation style is interpreted to be “Mississippi Valley-type” and shows some intriguing similarities to its neighbouring Abra lead-zinc-silver deposit that is also hosted in the Irregully rock formation.

But Miramar will be hoping this story doesn’t turn out like that of Abra owner Galena Mining, which ran aground earlier this year with debts totalling some $160 million to international lenders because of a poor lead-zinc environment. Fortunately for Miramar, copper seems to be the ticket this week and maybe that’s what Galena’s deposit was missing.

Our final Runner for the week is Stelar Metals, which shot up more than 101 per cent this week on … yep, you guessed it, copper rock chip samples.

High-grade copper findings were sampled along a 3km strike at its Baratta project in South Australia, returning grades of up to 28.7 per cent. It is a region Stelar says shows similarities to the prolific Central African Copper Belt (CACB) – the biggest and most prolific mineralised sediment-hosted copper province known on Earth.

The company reported 21 of the 72 samples exceeding grades of 10 per cent copper, underscoring the potential of the historically-productive Baratta site featuring a mine that produced copper ore between 1896 and 1904.

Rather unfortunately for Stelar, the traditional owners in the Adnyamathanha native title organisation remains in administration. The company says it will continue to monitor the native title situation and will lodge applications for drilling at Baratta when the traditional owner organisation comes out of administration.

If copper is the flavour of the month, then it seems rock chip samples were this week’s tipple of the week. Now, we’ll just have to wait and see if the all-time highs for the index will overlap with a return of interest to the small end of town.
