Many important considerations impact software design. Business goals, user goals, user context, cultural considerations, platform paradigms, branding requirements, devices … the list goes on and on. While a primary focus for any software design effort should be the data or other content that’s being displayed, this keystone element is often given short shrift. This is unfortunate and shortsighted. Given the focus it your content will receive, it should be a primary consideration during the design process.

It is a common practice to represent data and content as “Lorem ipsum,” repeating data, or simply using “best case scenario” data. In reality, this isn’t what will be experienced in the final product. The data you have to work with can drastically affect the final design, and the design will influence the type, format, and presentation of data.

From solutions of prehnitene and the ternary halides (SnCl)[MCl4] (M = Al, Ga) in chloro­benzene, the new cationic SnII–π-arene complexes catena-poly[[chlorido­aluminate(III)]-tri-μ-chlorido-4':1κ2Cl,1:2κ4Cl-[(η6-1,2,3,4-tetra­meth­yl­benzene)­tin(II)]-di-μ-chlorido-2:3κ4Cl-[(η6-1,2,3,4-tetra­methyl­benzene)­tin(II)]-di-μ-chlorido-3:4κ4Cl-[chlorido­aluminate(III)]-μ-chlorido-4:1'κ2Cl], [Al2Sn2Cl10(C10H14)2]n, (1) and catena-poly[[chlorido­gallate(III)]-tri-μ-chlor­ido-4':1κ2Cl,1:2κ4Cl-[(η6-1,2,3,4-tetra­methyl­benzene)­tin(II)]-di-μ-chlorido-2:3κ4Cl-[(η6-1,2,3,4-tetra­methyl­benzene)­tin(II)]-di-μ-chlorido-3:4κ4Cl-[chlor­ido­gallate(III)]-μ-chlorido-4:1'κ2Cl], [Ga2Sn2Cl10(C10H14)2]n, (2), were isolated. In these first main-group metal–prehnitene complexes, the distorted η6 arene π-bonding to the tin atoms of the Sn2Cl22+ moieties in the centre of [{1,2,3,4-(CH3)4C6H2}2Sn2Cl2][MCl4]2 repeating units (site symmetry overline{1}) is characterized by: (i) a significant ring slippage of ca 0.4 Å indicated by the dispersion of Sn—C distances [1: 2.881 (2)–3.216 (2) Å; 2: 2.891 (3)–3.214 (3) Å]; (ii) the non-methyl-substituted arene C atoms positioned closest to the SnII central atom; (iii) a pronounced tilt of the plane of the arene ligand against the plane of the central (Sn2Cl2)2+ four-membered ring species [1: 15.59 (11)°, 2: 15.69 (9)°]; (iv) metal–arene bonding of medium strength as illustrated by application of the bond-valence method in an indirect manner, defining the π-arene bonding inter­action of the SnII central atoms as s(SnII—arene) = 2 − Σs(SnII—Cl), that gives s(SnII—arene) = 0.37 and 0.38 valence units for the aluminate and the gallate, respectively, indicating that comparatively strong main-group metal–arene bonding is present and in line with the expectation that [AlCl4]− is the slightly weaker coordinating anion as compared to [GaCl4]−.

Three new isotypic heteropolynuclear complexes, namely penta­aqua­carbonato­penta­kis­(glycinehydroxamato)nitrato­penta­copper(II)lanthanide(III) x-hydrate, [LnCu5(GlyHA)5(CO3)(NO3)(H2O)5]·xH2O (GlyHA2− is glycine­hydrox­amate, N-hy­droxy­glycinamidate or amino­aceto­hydroxamate, C2H4N2O22−), with lanthanide(III) (LnIII) = gadolinium (Gd, 1, x = 3.5), dysprosium (Dy, 2, x = 3.28) and holmium (Ho, 3, x = 3.445), within a 15-metallacrown-5 class were obtained on reaction of lanthanide(III) nitrate, copper(II) acetate and sodium glycinehydroxamate. Complexes 1–3 contain five copper(II) ions and five bridging GlyHA2− anions, forming a [CuGlyHA]5 metallamacrocyclic core. The LnIII ions are coordinated to the metallamacrocycle through five O-donor hydroxamates. The electroneutrality of complexes 1–3 is achieved by a bidentate carbonate anion coordinated to the LnIII ion and a monodentate nitrate anion coordinated apically to one of the copper(II) ions of the metallamacrocycle. The lattice parameters of complexes 1–3 are similar to those previously reported for an EuIII–CuII 15-metallacrown-5 complex with glycine­hydroxamate of proposed composition [EuCu5(GlyHA)5(OH)(NO3)2(H2O)4]·3.5H2O [Stemmler et al. (1999). Inorg. Chem. 38, 2807–2817]. High-quality X-ray data obtained for 1–3 have allowed a re-evaluation of the X-ray data solution proposed earlier for the EuCu5 complex and suggest that the formula is actually [EuCu5(GlyHA)5(CO3)(NO3)(H2O)5]·3.5H2O.

X-ray imaging of soft materials is often difficult because of the low contrast of the components. This particularly applies to frozen hydrated biological cells where the feature of interest can have a similar density to the surroundings. As a consequence, a high dose is often required to achieve the desired resolution. However, the maximum dose that a specimen can tolerate is limited by radiation damage. Results from 3D coherent diffraction imaging (CDI) of frozen hydrated specimens have given resolutions of ∼80 nm compared with the expected resolution of 10 nm predicted from theoretical considerations for identifying a protein embedded in water. Possible explanations for this include the inapplicability of the dose-fractionation theorem, the difficulty of phase determination, an overall object-size dependence on the required fluence and dose, a low contrast within the biological cell, insufficient exposure, and a variety of practical difficulties such as scattering from surrounding material. A recent article [Villaneuva-Perez et al. (2018), Optica, 5, 450–457] concluded that imaging by Compton scattering gave a large dose advantage compared with CDI because of the object-size dependence for CDI. An object-size dependence would severely limit the applicability of CDI and perhaps related coherence-based methods for structural studies. This article specifically includes the overall object size in the analysis of the fluence and dose requirements for coherent imaging in order to investigate whether there is a dependence on object size. The applicability of the dose-fractionation theorem is also discussed. The analysis is extended to absorption-based imaging and imaging by incoherent scattering (Compton) and fluorescence. This article includes analysis of the dose required for imaging specific low-contrast cellular organelles as well as for protein against water. This article concludes that for both absorption-based and coherent diffraction imaging, the dose-fractionation theorem applies and the required dose is independent of the overall size of the object. For incoherent-imaging methods such as Compton scattering, the required dose depends on the X-ray path length through the specimen. For all three types of imaging, the dependence of fluence and dose on a resolution d goes as 1/d4 when imaging uniform-density voxels. The independence of CDI on object size means that there is no advantage for Compton scattering over coherent-based imaging methods. The most optimistic estimate of achievable resolution is 3 nm for imaging protein molecules in water/ice using lensless imaging methods in the water window. However, the attainable resolution depends on a variety of assumptions including the model for radiation damage as a function of resolution, the efficiency of any phase-retrieval process, the actual contrast of the feature of interest within the cell and the definition of resolution itself. There is insufficient observational information available regarding the most appropriate model for radiation damage in frozen hydrated biological material. It is advocated that, in order to compare theory with experiment, standard methods of reporting results covering parameters such as the feature examined (e.g. which cellular organelle), resolution, contrast, depth of the material (for 2D), estimate of noise and dose should be adopted.

Propagation-based phase-contrast X-ray imaging is by now a well established imaging technique, which – as a full-field technique – is particularly useful for tomography applications. Since it can be implemented with synchrotron radiation and at laboratory micro-focus sources, it covers a wide range of applications. A limiting factor in its development has been the phase-retrieval step, which was often performed using methods with a limited regime of applicability, typically based on linearization. In this work, a much larger set of algorithms, which covers a wide range of cases (experimental parameters, objects and constraints), is compiled into a single toolbox – the HoloTomoToolbox – which is made publicly available. Importantly, the unified structure of the implemented phase-retrieval functions facilitates their use and performance test on different experimental data.

New fitting analyses of two-dimensional diffraction-spot shapes are demonstrated to evaluate strain, strain distribution and domain size in a crystalline ultra-thin film. The evaluations are displayed as residual and population maps as a function of strain or domain size.

In late April, Metalla Royalty & Streaming acquired two royalties, one of which was a Gross Overriding Royalty (GOR) on NuLegacy Gold Corporation (NUG:TSX.V; NULGF:OTCQX) flagship Red Hill project, a Carlin-style deposit in Nevada's world-famous Cortez trend.

To be clear, this was a transaction between Metalla and a private company; no cash or other remuneration flowed to NuLegacy. However, this news is still exciting and thought provoking as it pertains to a potential (implied) valuation of Red Hill. So much so, that—CEO/director of Finance and Marketing—Albert Matter put out this press release highlighting it. {corporate presentation}

Metalla's news is applicable to NuLegacy for a number of reasons. Let me start by saying I know the Metalla team, I've written about the company several times (although not recently).

This is a smart, hard-working, market-savvy group, with global experience, integrity and expertise. When dealing in streams and royalties, it's all about industry connections, market knowledge and deal flow. Metalla has that and is up to its eyeballs in deal flow (deals it can make or pass on).

Takeaways on implied valuation of NuLegacy's Red Hill project?

That's why this news is so interesting. It represents a reliable, unbiased vote of confidence in NuLegacy's Red Hill project. I was able to track down the president, CEO and a director of Metalla, Mr. Brett Heath, to ask him about his team's view of NuLegacy, their management and technical teams, and the Red Hill project,

"The Red Hill project is very interesting due to its location & position within the Cortez trend of Nevada that hosts globally significant mines & projects, specifically Cortez Hills, Pipeline & Goldrush. Although many near-surface deposits have been discovered, several blind deposits similar to Goldrush have yet to be found.

"NuLegacy's Rift Anticline is a promising new drill target, a chance to discover a large, high-grade deposit. The close proximity of Red Hill to Goldrush heavily influenced our understanding of the geology at Red Hill. Specifically, it allowed us to better understand that the Rift Anticline has similar stratigraphy to Goldrush, and similar mineralization events nearby."

Investors, shareholders and analysts are trying to figure out what (if any) read-throughs there are in terms of the valuation of the Red Hill project.

From the press release:

"Valuing Gross Overriding Royalties ("GORs") is a complicated business made easier in this instance by the straightforward nature of the [transaction] …. prorating the US$4 million purchase price for the total of 2% GOR that was acquired…. values a 1% GOR in the Red Hill project at ~US$2 million."

What this valuation exercise boils down to is how does the value of a 1% GOR compare to a conventional working interest in the same project? GORs are highly case specific, so I will give a range of possibilities. Many factors make GORs unique, but a rule of thumb is that a 1% GOR equates to a 5% working interest.

However, due to the unknown terms of this particular GOR, let's assume that the 1% GOR is equal to between a 5% and 10% working interest. By extending the range higher than 5%, more conservative valuations for Red Hull are obtained. In the chart below one can see that the implied ~US$2 million paid for a 1% GOR equals C$2.8 million at the current exchange rate.

Therefore, Red Hill's indicative valuation could be viewed as C$28 million to C$56 million, or C$0.08 to C$0.15 per share. Currently, the stock's trading at C$0.07. The company has a cash balance of C$4.5 million. {see corporate presentation}. I believe the C$0.08 to C$0.15/share range is conservative because Metalla's purchase of the GOR had a built-in profit expectation. The true ascribed value of a 1% GOR on the Red Hill project might be higher than C$2.8 million.

A true vote of confidence in NuLegacy Gold

Perhaps more important than an implied (subjective) valuation of Red Hill are the following takeaways. First, Metalla not only likes Red Hill, it must also feel good about the long-term prospects for Nevada and the U.S. Metalla looks at hundreds of deals a year from all over the world. Management can, and does, invest in dozens of jurisdictions.

Yet, in April 2020, it chose the U.S., …. Nevada …. the Cortez Trend…. Second, it chose a project that's pre-maiden resource. Remember, Metalla has paid out ~C$2.8 million, but doesn't make a penny of that back unless it re-sells some or all of the GOR it acquired, or Red Hill reaches commercial production. Therefore, I argue that investing at this relatively early stage is a stamp of approval in the extensive work done to date at Red Hill.

That Metalla chose to deploy capital in a gold asset rather than a silver asset, despite the gold-silver ratio being near an all-time high (over 110 to 1) seems promising. Finally, it chose the U.S. at a time when the currencies of Mexico, Australia, Canada and others have weakened considerably vs. the U.S. dollar, making exploration cheaper in those countries. One must have conviction to choose Red Hill over dozens of public and private, pre-maiden resource, projects around the globe.

In the end, a good project in a great jurisdiction is only as prospective as its technical/management teams. NuLegacy has prudently advanced Red Hill in good times and bad. For most of NuLegacy's existence, the gold price traded between about $1,050 and $1,400/oz.

Gold price at $1,730/oz. is a game-changer….

Now gold is hovering around $1,730/oz after almost touching $1,800/oz in March. This is a game-changer for juniors like NuLegacy that have tremendous blue-sky potential, (look at neighboring mines and development projects, some of the best on the planet) but like most juniors, have limited funding to conduct aggressive drill programs in a strong gold price environment.

A savvy company betting on the Red Hill project is yet another indication that the time has come for precious metal players to become more active in M&A.

The day that Barrick commits its deep experience (and deep pockets!) to NuLegacy's Red Hill, all royalties held on that project would soar in value. Why? The timeline to potential production would be shortened, perhaps by years, (more drilling, less investor hand holding, perhaps skipping a PEA or a PFS). The scope of the project would become larger—more drilling across a wider footprint (a 108 sq. km land package).

The value of the royalties could double, triple, quadruple…. who knows? The share price at which NuLegacy gets taken out could also be meaningfully stronger. After all the company has been through, I don't think the Board would sell the company below C$0.30/share. At least not with the gold price at $1,730/oz (or higher). Readers are reminded that C$1.5 billon OceanaGold Corp. & giant natural resources fund Tocqueville own a combined 21.5% of the company.

Might there be a bidding war for NuLegacy?

In a best case example then, there could be multiple bidders for NuLegacy. This is not nearly as crazy as it sounds, especially if the gold price keeps going up, or if the next (fully funded) drill program hits the mark. If Barrick were to make a move, OceanaGold, Newmont, or even Tocqueville (they could hold out for higher price) might have something to say about it.

Those entities, and/or other mid-tiers/majors in Nevada or around the world would keep Barrick honest. Over the years NuLegacy has been in touch with several well-known names, but I never know who they're talking with at any given time. Make no mistake, Barrick is best positioned by virtue of having the most synergies with Red Hill, so it can afford to pay several more pennies per share if need be. That's how a share price of C$0.30+ becomes possible.

Bottom line, NuLegacy Gold (TSX-V: NUG) / (OTCQX: NULGF) is a high-risk exploration play, but I believe a good speculation. There's no better time to be buying high-risk exploration than when the prices of the metals being explored for are moving up.

As more attention is drawn to NuLegacy, its team, the undisputed safety of Nevada, the prolific nature of the Cortez Trend, etc., I think there's compelling relative and absolute value here that readers should consider investigating further.
